+## How to create an Issue
+
+Hello!
+
+You may use the Issue Tracker to submit bug reports, feature requests or suggestions. You may ask for help or advice as well. However please read this wall of text before doing so. The amount of incomplete or ambiguous requests occasionally becomes overwhelming, so please do your best to clarify your request. Thank you!
+
+**Prerequisites for new users of dear imgui:**
+- Please read the FAQ in imgui.cpp.
+- Please read misc/fonts/README.txt if your question relates to fonts or text.
+- Please run ImGui::ShowDemoWindow() to explore the demo and its sources.
+- Please use the Search function of GitHub to look for similar issues. You may also browse issues by tags.
+- Please use the Search function of your IDE to search in the code for comments related to your situation.
+- If you get a assert, use a debugger to locate the line triggering it and read the comments around the assert.
+
+**Guidelines to report an issue or ask a question:**
+- Try to provide a Minimal, Complete and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem. An ideal submission includes a small piece of code that anyone can paste in one of the examples/ application to understand and reproduce it. Narrowing your problem to its shortest and purest form is often the easiest way to understand it. Often while creating the MCVE you will end up solving the problem!
+- Try to attach screenshots to clarify the context. They often convey useful information that are omitted by the description. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
+- If you are discussing an assert or a crash, please provide a debugger callstack.
+- Please provide your imgui version number.
+- Please state if you have made substantial modifications to your copy of imgui.
+- When discussing issues related to rendering or inputs, please state which OS you are using, and if you are using a vanilla copy of one of the back end (imgui_impl_xxx files), or a modified one, or if you built your own.
+- When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.).
+- Due to frequent abuse of this service from a certain category of users, if your GitHub account is anonymous and was created five minutes ago please understand that your post will receive more scrutiny and less patience for incomplete questions.
+
+If you have been using dear imgui for a while and/or have been using C/C++ for several years and/or have demonstrated good behavior here, it is ok to not fullfill every item to the letter. Those are guidelines and experienced users of dear imgui will know what information are useful in a given context.
+
+## How to create an Pull Request
+
+- If you are adding a feature, please describe the usage context (how you intend to use it, why you need it, etc.).
+- Try to attach screenshots to clarify the context and demonstrate the feature at a glance. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
+- Make sure you create a branch for the pull request. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).

+CHANGELOG
+
+-----------------------------------------------------------------------
+
+This document holds the programmer changelog that we also use in release notes.
+We generally fold multiple commits pertaining to the same topic as a single entry, and simplify various things.
+
+Release notes: (with links and screenshots)
+ https://github.com/ocornut/imgui/releases
+
+Changes to the examples/bindings are included within the individual .cpp files in examples.
+
+Individual commits:
+ https://github.com/ocornut/imgui/commits/master
+
+Report issues, ask questions:
+ https://github.com/ocornut/imgui/issues
+
+-----------------------------------------------------------------------
+
+WHEN TO UPDATE?
+
+It is generally safe to sync to the latest commit in master. The library is fairly stable and regressions tends to be fixed fast when reported.
+Keeping your copy of dear imgui updated once in a while is recommended.
+
+HOW TO UPDATE?
+
+- Overwrite every file except imconfig.h (if you have modified it).
+- You may also locally branch to modify imconfig.h and merge latest into your branch.
+- Read the `Breaking Changes` section (in imgui.cpp or here in the Changelog).
+- If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it.
+- If you are dropping this repository in your codebase, please leave the demo and text files in there, they will be useful.
+- You may diff your previous Changelog with the one you just copied and read that diff.
+- You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols. Doing it every once in a while is a good way to make sure you are not using obsolete symbols. Dear ImGui is in active development API updates have a little more frequent lately. They are carefully documented and should not affect all users.
+- Please report any issue!

+VERSION 1.60 (Released 2018-04-07)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.60
+
+The gamepad/keyboard navigation branch (which has been in the work since July 2016) has been merged.
+Gamepad/keyboard navigation is still marked as Beta and has to be enabled explicitly.
+Various internal refactors have also been done, as part of the navigation work and as part of the upcoing viewport/docking work.
+
+Breaking Changes:
+
+ - Obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render().
+ e.g. with example back-ends, call ImDrawData* draw_data = ImGui::GetDrawData(); ImGui_ImplXXXX_RenderDrawData(draw_data).
+ - Reorganized context handling to be more explicit: (#1599)
+ - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
+ - removed Shutdown() function, as DestroyContext() serve this purpose. If you are using an old back-end from the examples/ folder, remove the line that calls Shutdown().
+ - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwhise CreateContext() will create its own font atlas instance.
+ - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
+ - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
+ - Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
+ - Fonts: Moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
+ - Fonts: changed ImFont::DisplayOffset.y to defaults to 0 instead of +1. Fixed vertical rounding of Ascent/Descent to match TrueType renderer.
+ If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619)
+ - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
+ - Obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
+ - Obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
+ - Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, not used by core, and honored by some binding ahead of merging the Nav branch).
+ - Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered style colors as the closing cross uses regular button colors now.
+ - Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
+ - Removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
+
+Other Changes:
+
+- Doc: Added a Changelog file in the repository to ease comparing versions (it goes back to dear imgui 1.48), until now it was only on GitHub.
+- Navigation: merged in the gamepad/keyboard navigation (about a million changes!). (#787, #323)
+ The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
+ - To use Gamepad Navigation:
+ - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
+ - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). Read imgui.cpp for more details.
+ - See https://github.com/ocornut/imgui/issues/1599 for recommended gamepad mapping or download PNG/PSD at http://goo.gl/9LgVZW
+ - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. Read imgui.cpp for more details.
+ - To use Keyboard Navigation:
+ - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. NewFrame() will automatically fill io.NavInputs[] based on your io.KeyDown[] + io.KeyMap[] arrays.
+ - Basic controls: arrows to navigate, Alt to enter menus, Space to activate item, Enter to edit text, Escape to cancel/close, Ctrl-Tab to focus windows, etc.
+ - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag will be set.
+ For more advanced uses, you may want to read from io.NavActive or io.NavVisible. Read imgui.cpp for more details.
+- Navigation: SetItemDefaultFocus() sets the navigation position in addition to scrolling. (#787)
+- Navigation: Added IsItemFocused(), added IsAnyItemFocused(). (#787)
+- Navigation: Added window flags: ImGuiWindowFlags_NoNav (== ImGuiWindowFlags_NoNavInputs | ImGuiWindowFlags_NoNavFocus).
+- Navigation: Style: Added ImGuiCol_NavHighlight, ImGuiCol_NavWindowingHighlight colors. (#787)
+- Navigation: TreeNode: Added ImGuiTreeNodeFlags_NavLeftJumpsBackHere flag to allow Nav Left direction to jump back to parent tree node from any of its child. (#1079)
+- Navigation: IO: Added io.ConfigFlags (input), io.NavActive (output), io.NavVisible (output). (#787)
+- Context: Removed the default global context and font atlas instances, which caused various problems to users of multiple contexts and DLL users. (#1565, #1599)
+ YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. Existing apps will assert/crash without it.
+- Context: Added SetAllocatorFunctions() to rewire memory allocators (as a replacement to previous parameters to CreateContext()). Allocators are shared by all contexts and imgui helpers. (#1565, #586, #992, #1007, #1558)
+- Context: You may pass a ImFontAtlas to CreateContext() to specify a font atlas to share. Shared font atlas are not owned by the context and not destroyed along with it. (#1599)
+- Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558)
+- IO: Added io.ConfigFlags for user application to store settings for imgui and for the back-end:
+ - ImGuiConfigFlags_NavEnableKeyboard: Enable keyboard navigation.
+ - ImGuiConfigFlags_NavEnableGamepad: Enable gamepad navigation (provided ImGuiBackendFlags_HasGamepad is also set by back-end).
+ - ImGuiConfigFlags_NavEnableSetMousePos: Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward.
+ - ImGuiConfigFlags_NoMouseCursorChange: Instruct back-end to not alter mouse cursor shape and visibility (by default the example back-end use mouse cursor API of the platform when available)
+ - ImGuiConfigFlags_NoMouse: Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information passed by the back-end.
+ - ImGuiConfigFlags_IsSRGB, ImGuiConfigFlags_IsTouchScreen: Flags for general application use.
+- IO: Added io.BackendFlags for back-end to store its capabilities (currently: _HasGamepad, _HasMouseCursors, _HasSetMousePos). This will be used more in the next version.
+- IO: Added ImGuiKey_Insert, ImGuiKey_Space keys. Setup in all example bindings. (#1541)
+- IO: Added Horizontal Mouse Wheel support for horizontal scrolling. (#1463) [@tseeker]
+- IO: Added IsAnyMouseDown() helper which is helpful for bindings to handle mouse capturing.
+- Window: Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else when dragging afterwards. (#1381, #1337)
+- Window: IsWindowHovered(): Added ImGuiHoveredFlags_AnyWindow, ImGuiFocusedFlags_AnyWindow flags (See Breaking Changes). Added to demo. (#1382)
+- Window: Added SetNextWindowBgAlpha() helper. Particularly helpul since the legacy 5-parameters version of Begin() has been marked as obsolete in 1.53. (#1567)
+- Window: Fixed SetNextWindowContentSize() with 0.0f on Y axis (or SetNextWindowContentWidth()) overwriting the contents size. Got broken on Dec 10 (1.53). (#1363)
+- ArrowButton: Added ArrowButton() given a cardinal direction (e.g. ImGuiDir_Left).
+- InputText: Added alternative clipboard shortcuts: Shift+Delete (cut), Ctrl+Insert (copy), Shift+Insert (paste). (#1541)
+- InputText: Fixed losing Cursor X position when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554)
+- InputText: Added ImGuiInputTextFlags_CharsScientific flag to also allow 'e'/'E' for input of values using scientific notation. Automatically used by InputFloat.
+- Style: Default style is now StyleColorsDark(), instead of the old StyleColorsClassic(). (#707)
+- Style: Enable window border by default. (#707)
+- Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181)
+- Style: Added style.MouseCursorScale help when using the software mouse cursor facility. (#939).
+- Style: Close button nows display a cross before hovering. Fixed cross positioning being a little off. Uses button colors for highlight when hovering. (#707)
+- Popup: OpenPopup() Always reopen existing popup. (Removed imgui_internal.h's OpenPopupEx() which was used for this.) (#1497, #1533).
+- Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse press. (~#439)
+- Popup: Better handling of user mistakenly calling OpenPopup() every frame (with reopen_existing option). The error will now be more visible and easier to understand. (#1497)
+- Popup: BeginPopup(): Exposed extra_flags parameter that are passed through to Begin(). (#1533)
+- Popup: BeginPopupModal: fixed the conditional test for SetNextWindowPos() which was polling the wrong window, which in practice made the test succeed all the time.
+- Tooltip: BeginTooltip() sets ImGuiWindowFlags_NoInputs flag.
+- Scrollbar: Fixed ScrollbarY enable test after ScrollbarX has been enabled being a little off (small regression from Nov 2017). (#1574)
+- Scrollbar: Fixed ScrollbarX enable test subtracting WindowPadding.x (this has been there since the addition of horizontal scroll bar!).
+- Columns: Clear offsets data when columns count changed. (#1525)
+- Columns: Fixed a memory leak of ImGuiColumnsSet's Columns vector. (#1529) [@unprompted]
+- Columns: Fixed resizing a window very small breaking some columns positioning (broken in 1.53).
+- Columns: The available column extent takes consideration of the right-most clipped pixel, so the right-most column may look a little wider but will contain the same amount of visible contents.
+- MenuBar: Fixed menu bar pushing a clipping rect outside of its allocated bound (usually unnoticeable).
+- TreeNode: nodes with the ImGuiTreeNodeFlags_Leaf flag correctly disable highlight when DragDrop is active. (#143, #581)
+- Drag and Drop: Increased payload type string to 32 characters instead of 8. (#143)
+- Drag and Drop: TreeNode as drop target displays rectangle over full frame. (#1597, #143)
+- DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559)
+- InputFloat: Allow inputing value using scientific notation e.g. "1e+10".
+- InputDouble: Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011)
+- Slider, Combo: Use ImGuiCol_FrameBgHovered color when hovered. (#1456) [@stfx]
+- Combo: BeginCombo(): Added ImGuiComboFlags_NoArrowButton to disable the arrow button and only display the wide value preview box.
+- Combo: BeginCombo(): Added ImGuiComboFlags_NoPreview to disable the preview and only display a square arrow button.
+- Combo: Arrow button isn't displayed over frame background so its blended color matches other buttons. Left side of the button isn't rounded.
+- PlotLines: plot a flat line if scale_min==scale_max. (#1621)
+- Fonts: Changed DisplayOffset.y to defaults to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer.
+ If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619)
+- Fonts: Updated stb_truetype from 1.14 to stb_truetype 1.19. (w/ include fix from some platforms #1622)
+- Fonts: Added optional FreeType rasterizer in misc/freetype. Moved from imgui_club repo. (#618) [@Vuhdo, @mikesart, @ocornut]
+- Fonts: Moved extra_fonts/ to misc/fonts/.
+- ImFontAtlas: Fixed cfg.MergeMode not reusing existing glyphs if available (always overwrote).
+- ImFontAtlas: Handle stb_truetype stbtt_InitFont() and stbtt_PackBegin() possible failures more gracefully, GetTexDataAsRGBA32() won't crash during conversion. (#1527)
+- ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple contexts. Also remove the last remaining undesirable dependency on ImGui in imgui_draw.cpp. (#939)
+- ImFontAtlas: Added ImFontAtlasFlags_NoPowerOfTwoHeight flag to disable padding font height to nearest power of two. (#1613)
+- ImFontAtlas: Added ImFontAtlasFlags_NoMouseCursors flag to disable baking software mouse cursors, mostly to save texture memory on very low end hardware. (#1613)
+- ImDrawList: Fixed AddRect() with antialiasing disabled (lower-right corner pixel was often missing, rounding looks a little better.) (#1646)
+- ImDrawList: Added CloneOutput() helper to facilitate the cloning of ImDrawData or ImDrawList for multi-threaded rendering.
+- Misc: Functions passed to libc qsort are explicitly marked cdecl to support compiling with vectorcall as the default calling convention. (#1230, #1611) [@RandyGaul]
+- Misc: ImVec2: added [] operator. This is becoming desirable for some code working of either axes independently. Better adding it sooner than later.
+- Misc: NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555)
+- Misc: Added IM_OFFSETOF() helper in imgui.h (previously was in imgui_internal.h)

+
+VERSION 1.53 (Released 2017-12-25)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.53
+
+Breaking Changes:
+
+- Renamed the emblematic `ShowTestWindow()` function to `ShowDemoWindow()`. Kept redirection function (will obsolete).
+- Renamed `GetItemsLineHeightWithSpacing()` to `GetFrameHeightWithSpacing()` for consistency. Kept redirection function (will obsolete).
+- Renamed `ImGuiTreeNodeFlags_AllowOverlapMode` flag to `ImGuiTreeNodeFlags_AllowItemOverlap`. Kept redirection enum (will obsolete).
+- Obsoleted `IsRootWindowFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootWindow)`. Kept redirection function (will obsolete). (#1382)
+- Obsoleted `IsRootWindowOrAnyChildFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382)
+- Obsoleted `IsRootWindowOrAnyChildHovered()` in favor of using `IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382)
+- Obsoleted `SetNextWindowContentWidth() in favor of using `SetNextWindowContentSize()`. Kept redirection function (will obsolete).
+- Renamed `ImGuiTextBuffer::append()` helper to `appendf()`, and `appendv()` to `appendfv()` for consistency. If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
+- ImDrawList: Removed 'bool anti_aliased = true' final parameter of `ImDrawList::AddPolyline()` and `ImDrawList::AddConvexPolyFilled()`. Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
+- Style, ImDrawList: Renamed `style.AntiAliasedShapes` to `style.AntiAliasedFill` for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags.
+- Style, Begin: Removed `ImGuiWindowFlags_ShowBorders` window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. `style.FrameBorderSize`, `style.WindowBorderSize`, `style.PopupBorderSize`).
+ Use `ImGui::ShowStyleEditor()` to look them up.
+ Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time.
+ It is recommended that you use the `StyleColorsClassic()`, `StyleColorsDark()`, `StyleColorsLight()` functions. Also see `ShowStyleSelector()`.
+- Style: Removed `ImGuiCol_ComboBg` in favor of combo boxes using `ImGuiCol_PopupBg` for consistency. Combo are normal popups.
+- Style: Renamed `ImGuiCol_ChildWindowBg` to `ImGuiCol_ChildBg`.
+- Style: Renamed `style.ChildWindowRounding` to `style.ChildRounding`, `ImGuiStyleVar_ChildWindowRounding` to `ImGuiStyleVar_ChildRounding`.
+- Removed obsolete redirection functions: SetScrollPosHere() - marked obsolete in v1.42, July 2015.
+- Removed obsolete redirection functions: GetWindowFont(), GetWindowFontSize() - marked obsolete in v1.48, March 2016.
+
+Other Changes:
+
+- Added `io.OptCursorBlink` option to allow disabling cursor blinking. (#1427)
+- Added `GetOverlayDrawList()` helper to quickly get access to a ImDrawList that will be rendered in front of every windows.
+- Added `GetFrameHeight()` helper which returns `(FontSize + style.FramePadding.y * 2)`.
+- Drag and Drop: Added Beta API to easily use drag and drop patterns between imgui widgets.
+ - Setup a source on a widget with `BeginDragDropSource()`, `SetDragDropPayload()`, `EndDragDropSource()` functions.
+ - Receive data with `BeginDragDropTarget()`, `AcceptDragDropPayload()`, `EndDragDropTarget()`.
+ - See ImGuiDragDropFlags for various options.
+ - The ColorEdit4() and ColorButton() widgets now support Drag and Drop.
+ - The API is tagged as Beta as it still may be subject to small changes.
+- Drag and Drop: When drag and drop is active, tree nodes and collapsing header can be opened by hovering on them for 0.7 seconds.
+- Renamed io.OSXBehaviors to io.OptMacOSXBehaviors. Should not affect users as the compile-time default is usually enough. (#473, #650)
+- Style: Added StyleColorsDark() style. (#707) [@dougbinks]
+- Style: Added StyleColorsLight() style. Best used with frame borders + thicker font than the default font. (#707)
+- Style: Added style.PopupRounding setting. (#1112)
+- Style: Added style.FrameBorderSize, style.WindowBorderSize, style.PopupBorderSize. Removed ImGuiWindowFlags_ShowBorders window flag!
+ Borders are now fully set up in the ImGuiStyle structure. Use ImGui::ShowStyleEditor() to look them up. (#707, fix #819, #1031)
+- Style: Various small changes to the classic style (most noticeably, buttons are now using blue shades). (#707)
+- Style: Renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
+- Style: Renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
+- Style: Removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. (#707)
+- Style: Made the ScaleAllSizes() helper rounds down every values so they are aligned on integers.
+- Focus: Added SetItemDefaultFocus(), which in the current (master) branch behave the same as doing `if (IsWindowAppearing()) SetScrollHere()`.
+ In the navigation branch this will also set the default focus. Prefer using this when creating combo boxes with `BeginCombo()` so your code will be forward-compatible with gamepad/keyboard navigation features. (#787)
+- Combo: Popup grows horizontally to accomodate for contents that is larger then the parent combo button.
+- Combo: Added BeginCombo()/EndCombo() API which allows use to submit content of any form and manage your selection state without relying on indices.
+- Combo: Added ImGuiComboFlags_PopupAlignLeft flag to BeginCombo() to prioritize keeping the popup on the left side (for small-button-looking combos).
+- Combo: Added ImGuiComboFlags_HeightSmall, ImGuiComboFlags_HeightLarge, ImGuiComboFlags_HeightLargest to easily provide desired popup height.
+- Combo: You can use SetNextWindowSizeConstraints() before BeginCombo() to specify specific popup width/height constraints.
+- Combo: Offset popup position by border size so that a double border isn't so visible. (#707)
+- Combo: Recycling windows by using a stack number instead of a unique id, wasting less memory (like menus do).
+- InputText: Added ImGuiInputTextFlags_NoUndoRedo flag. (#1506, #1508) [@ibachar]
+- Window: Fixed auto-resize allocating too much space for scrollbar when SizeContents is bigger than maximum window size (fixes c0547d3). (#1417)
+- Window: Child windows with MenuBar use regular WindowPadding.y so layout look consistent as child or as a regular window.
+- Window: Begin(): Fixed appending into a child window with a second Begin() from a different window stack querying the wrong window for the window->Collapsed test.
+- Window: Calling IsItemActive(), IsItemHovered() etc. after a call to Begin() provides item data for the title bar, so you can easily test if the title bar is being hovered, etc. (#823)
+- Window: Made it possible to use SetNextWindowPos() on a child window.
+- Window: Fixed a one frame glitch. When an appearing window claimed the focus themselves, the title bar wouldn't use the focused color for one frame.
+- Window: Added ImGuiWindowFlags_ResizeFromAnySide flag to resize from any borders or from the lower-left corner of a window. This requires your backend to honor GetMouseCursor() requests for full usability. (#822)
+- Window: Sizing fixes when useing SetNextWindowSize() on individual axises.
+- Window: Hide new window for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. (#1694)
+- Window: Made mouse wheel scrolling accomodate better to windows that are smaller than the scroll step.
+- Window: SetNextWindowContentSize() adjust for the size of decorations (title bar/menu bar), but _not_ for borders are we consistently make borders not affect layout.
+ If you need a non-child window of an exact size with border enabled but zero window padding, you'll need to accodomate for the border size yourself.
+- Window: Using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. (#1380, #1502)
+- Window: Active Modal window always set the WantCaptureKeyboard flag. (#744)
+- Window: Moving window doesn't use accumulating MouseDelta so straying out of imgui boundaries keeps moved imgui window at the same cursor-relative position.
+- Window: BeginChild() which an explicit name doesn't include the hash within the internal window name. (#1698)
+- IsWindowFocused(): Added ImGuiFocusedFlags_ChildWindows flag to include child windows in the focused test. (#1382).
+- IsWindowFocused(): Added ImGuiFocusedFlags_RootWindow flag to start focused test from the root (top-most) window. Obsolete IsRootWindowFocused(). (#1382)
+- IsWindowHovered(): Added ImGuiHoveredFlags_ChildWindows flag to include child windows in the hovered test. (#1382).
+- IsWindowHovered(): Added ImGuiHoveredFlags_RootWindow flag to start hovered test from the root (top-most) window. The combination of both flags obsoletes IsRootWindowOrAnyChildHovered(). (#1382)
+- IsWindowHovered(): Fixed return value when an item is active to use the same logic as IsItemHovered(). (#1382, #1404)
+- IsWindowHovered(): Always return true when current window is being moved. (#1382)
+- Scrollbar: Fixed issues with vertical scrollbar flickering/appearing, typically when manually resizing and using a pattern of filling available height (e.g. full sized BeginChild).
+- Scrollbar: Minor graphical fix for when scrollbar don't have enough visible space to display the full grab.
+- Scrolling: Fixed padding and scrolling asymetry where lower/right sides of a window wouldn't use WindowPadding properly + causing minor scrolling glitches.
+- Tree: TreePush with zero arguments was ambiguous. Resolved by making it call TreePush(const void*). [@JasonWilkins]
+- Tree: Renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. (#600, #1330)
+- MenuBar: Fixed minor rendering issues on the right size when resizing a window very small and using rounded window corners.
+- MenuBar: better software clipping to handle small windows, in particular child window don't have minimum constraints so we need to render clipped menus better.
+- BeginMenu(): Tweaked the Arrow/Triangle displayed on child menu items.
+- Columns: Clipping columns borders on Y axis on CPU because some Linux GPU drivers appears to be unhappy with triangle spanning large regions. (#125)
+- Columns: Added ImGuiColumnsFlags_GrowParentContentsSize to internal API to restore old content sizes behavior (may be obsolete). (#1444, #125)
+- Columns: Columns width is no longer lost when dragging a column to the right side of the window, until releasing the mouse button you have a chance to save them. (#1499, #125). [@ggtucker]
+- Columns: Fixed dragging when using a same of columns multiple times in the frame. (#125)
+- Indent(), Unindent(): Allow passing negative values.
+- ColorEdit4(): Made IsItemActive() return true when picker popup is active. (#1489)
+- ColorEdit4(): Tweaked tooltip so that the color button aligns more correctly with text.
+- ColorEdit4(): Support drag and drop. Color buttons can be used as drag sources, and ColorEdit widgets as drag targets. (#143)
+- ColorPicker4(): Fixed continously returning true when holding mouse button on the sat/value/alpha locations. We only return true on value change. (#1489)
+- NewFrame(): using literal strings in the most-frequently firing IM_ASSERT expressions to increase the odd of programmers seeing them (especially those who don't use a debugger).
+- NewFrame() now asserts if neither Render or EndFrame have been called. Exposed EndFrame(). Made it legal to call EndFrame() more than one. (#1423)
+- ImGuiStorage: Added BuildSortByKey() helper to rebuild storage from stratch.
+- ImFont: Added GetDebugName() helper.
+- ImFontAtlas: Added missing Thai punctuation in the GetGlyphRangesThai() ranges. (#1396) [@nProtect]
+- ImDrawList: Removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Anti-aliasing is controlled via the regular style.AntiAliased flags.
+- ImDrawList: Added ImDrawList::AddImageRounded() helper. (#845) [@thedmd]
+- ImDrawList: Refactored to make ImDrawList independant of ImGui. Removed static variable in PathArcToFast() which caused linking issues to some.
+- ImDrawList: Exposed ImDrawCornerFlags, replaced occurences of ~0 with an explicit ImDrawCornerFlags_All. NB: Inversed BotLeft (prev 1<<3, now 1<<2) and BotRight (prev 1<<2, now 1<<3).
+- ImVector: Added ImVector::push_front() helper.
+- ImVector: Added ImVector::contains() helper.
+- ImVector: insert() uses grow_capacity() instead of using grow policy inconsistent with push_back().
+- Internals: Remove requirement to define IMGUI_DEFINE_PLACEMENT_NEW to use the IM_PLACEMENT_NEW macro. (#1103)
+- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_NoHoldingActiveID flag from incorrectly setting the ActiveIdClickOffset field.
+ This had no known effect within imgui code but could have affected custom drag and drop patterns. And it is more correct this way! (#1418)
+- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_AllowOverlapMode to avoid temporarily activating widgets on click before they have been correctly double-hovered. (#319, #600)
+- Internals: Added SplitterBehavior() helper. (#319)
+- Internals: Added IM_NEW(), IM_DELETE() helpers. (#484, #504, #1517)
+- Internals: Basic refactor of the settings API which now allows external elements to be loaded/saved.
+- Demo: Added ShowFontSelector() showing loaded fonts.
+- Demo: Added ShowStyleSelector() to select among default styles. (#707)
+- Demo: Renamed the emblematic ShowTestWindow() function to ShowDemoWindow().
+- Demo: Style Editor: Added a "Simplified settings" sections with checkboxes for border size and frame rounding. (#707, #1019)
+- Demo: Style Editor: Added combo box to select stock styles and select current font when multiple are loaded. (#707)
+- Demo: Style Editor: Using local storage so Save/Revert button makes more sense without code passing its storage. Aadded horizontal scroll bar. Fixed Save/Revert button to be always accessible. (#1211)
+- Demo: Console: Fixed context menu issue. (#1404)
+- Demo: Console: Fixed incorrect positioning which was hidden by a minor scroll issue (this would affect people who copied the Console code as is).
+- Demo: Constrained Resize: Added more test cases. (#1417)
+- Demo: Custom Rendering: Fixed clipping rectangle extruding out of parent window.
+- Demo: Layout: Removed unnecessary and misleading BeginChild/EndChild calls.
+- Demo: The "Color Picker with Palette" demo supports drag and drop. (#143)
+- Demo: Display better mouse cursor info for debugging backends.
+- Demo: Stopped using rand() function in demo code.
+- Examples: Added a handful of extra comments (about fonts, third-party libraries used in the examples, etc.).
+- Examples: DirectX9: Handle loss of D3D9 device (D3DERR_DEVICELOST). (#1464)
+- Examples: Added null_example/ which is helpful for quick testing on multiple compilers/settings without relying on graphics library.
+- Fix for using alloca() in "Clang with Microsoft Codechain" mode.
+- Various fixes, optimizations, comments.

+-----------------------------------------------------------------------
+
+VERSION 1.52 (2017-10-27)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.52
+
+Breaking Changes:
+
+- IO: `io.MousePos` needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing, instead of ImVec2(-1,-1) as previously) This is needed so we can clear `io.MouseDelta` field when the mouse is made available again.
+- Renamed `AlignFirstTextHeightToWidgets()` to `AlignTextToFramePadding()`. Kept inline redirection function (will obsolete).
+- Obsoleted the legacy 5 parameters version of Begin(). Please avoid using it. If you need a transparent window background, uses `PushStyleColor()`. The old size parameter there was also misleading and equivalent to calling `SetNextWindowSize(size, ImGuiCond_FirstTimeEver)`. Kept inline redirection function (will obsolete).
+- Obsoleted `IsItemHoveredRect()`, `IsMouseHoveringWindow()` in favor of using the newly introduced flags of `IsItemHovered()` and `IsWindowHovered()`. Kept inline redirection function (will obsolete). (#1382)
+- Removed `IsItemRectHovered()`, `IsWindowRectHovered()` recently introduced in 1.51 which were merely the more consistent/correct names for the above functions which are now obsolete anyway. (#1382)
+- Changed `IsWindowHovered()` default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. (#1382)
+- Renamed imconfig.h's `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS` to `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS` for consistency.
+
+Other Changes:
+
+- ProgressBar: fixed rendering when straddling rounded area. (#1296)
+- SliderFloat, DragFloat: Using scientific notation e.g. "%.1e" in the displayed format string doesn't mistakenly trigger rounding of the value. [@MomentsInGraphics]
+- Combo, InputFloat, InputInt: Made the small button on the right side align properly with the equivalent colored button of ColorEdit4().
+- IO: Tweaked logic for `io.WantCaptureMouse` so it now outputs false when e.g. hovering over void while an InputText() is active. (#621) [@pdoane]
+- IO: Fixed `io.WantTextInput` from mistakenly outputting true when an activated Drag or Slider was previously turned into an InputText(). (#1317)
+- Misc: Added flags to `IsItemHovered()`, `IsWindowHovered()` to access advanced hovering-test behavior. Generally useful for popups and drag'n drop behaviors: (relates to ~#439, #1013, #143, #925)
+ - `ImGuiHoveredFlags_AllowWhenBlockedByPopup`
+ - `ImGuiHoveredFlags_AllowWhenBlockedByActiveItem`
+ - `ImGuiHoveredFlags_AllowWhenOverlapped`
+ - `ImGuiHoveredFlags_RectOnly`
+- Input: Added `IsMousePosValid()` helper.
+- Input: Added `GetKeyPressedAmount()` to easily measure press count when the repeat rate is faster than the frame rate.
+- Input/Focus: Disabled TAB and Shift+TAB when CTRL key is held.
+- Checkbox: Now rendering a tick mark instead of a full square.
+- ColorEdit4: Added "Copy as..." option in context menu. (#346)
+- ColorPicker: Improved ColorPicker hue wheel color interpolation. (#1313) [@thevaber]
+- ColorButton: Reduced bordering artefact that would be particularly visible with an opaque Col_FrameBg and FrameRounding enabled.
+- ColorButton: Fixed rendering color button with a checkerboard if the transparency comes from the global style.Alpha and not from the actual source color.
+- TreeNode: Added `ImGuiTreeNodeFlags_FramePadding` flag to conveniently create a tree node with full padding at the beginning of a line, without having to call `AlignTextToFramePadding()`.
+- Trees: Fixed calling `SetNextTreeNodeOpen()` on a collapsed window leaking to the first tree node item of the next frame.
+- Layout: Horizontal layout is automatically enforced in a menu bar, so you can use non-MenuItem elements without calling SameLine().
+- Separator: Output a vertical separator when used inside a menu bar (or in general when horizontal layout is active, but that isn't exposed yet!).
+- Windows: Added `IsWindowAppearing()` helper (helpful e.g. as a condition before initializing some of your own things.).
+- Windows: Fixed title bar color of top-most window under a modal window.
+- Windows: Fixed not being able to move a window by clicking on one of its child window. (#1337, #635)
+- Windows: Fixed `Begin()` auto-fit calculation code that predict the presence of a scrollbar so it works better when window size constraints are used.
+- Windows: Fixed calling `Begin()` more than once per frame setting `window_just_activated_by_user` which in turn would set enable the Appearing condition for that frame.
+- Windows: The implicit "Debug" window now uses a "Debug##Default" identifier instead of "Debug" to allow user creating a window called "Debug" without losing their custom flags.
+- Windows: Made the `ImGuiWindowFlags_NoMove` flag properly inherited from parent to child. In a setup with ParentWindow (no flag) -> Child (NoMove) -> SubChild (no flag), the user won't be able to move the parent window by clicking on SubChild. (#1381)
+- Popups: Popups can be closed with a right-click anywhere, without altering focus under the popup. (~#439)
+- Popups: `BeginPopupContextItem()`, `BeginPopupContextWindow()` are now setup to allow reopening a context menu by right-clicking again. (~#439)
+- Popups: `BeginPopupContextItem()` now supports a NULL string identifier and uses the last item ID if available.
+- Popups: Added `OpenPopupOnItemClick()` helper which mimic `BeginPopupContextItem()` but doesn't do the BeginPopup().
+- MenuItem: Only activating on mouse release. [@Urmeli0815] (was already fixed in nav branch).
+- MenuItem: Made tick mark thicker (thick mark?).
+- MenuItem: Tweaks to be usable inside a menu bar (nb: it looks like a regular menu and thus is misleading, prefer using Button() and regular widgets in menu bar if you need to). (#1387)
+- ImDrawList: Fixed a rare draw call merging bug which could lead to undisplayed triangles. (#1172, #1368)
+- ImDrawList: Fixed a rare bug in `ChannelsMerge()` when all contents has been clipped, leading to an extraneous draw call being created. (#1172, #1368)
+- ImFont: Added `AddGlyph()` building helper for use by custom atlas builders.
+- ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas. You can map them as font glyphs, or use them for custom purposes.
+ After the atlas is built you can query the position of your rectangles in the texture and then copy your data there. You can use this features to create e.g. full color font-mapped icons.
+- ImFontAtlas: Fixed fall-back handling when merging fonts, if a glyph was missing from the second font input it could have used a glyph from the first one. (#1349) [@inolen]
+- ImFontAtlas: Fixed memory leak on build failure case when stbtt_InitFont failed (generally due to incorrect or supported font type). (#1391) (@Moka42)
+- ImFontConfig: Added `RasterizerMultiply` option to alter the brightness of individual fonts at rasterization time, which may help increasing readability for some.
+- ImFontConfig: Added `RasterizerFlags` to pass options to custom rasterizer (e.g. the [imgui_freetype](https://github.com/ocornut/imgui_club/tree/master/imgui_freetype) rasterizer in imgui_club has such options).
+- ImVector: added resize() variant with initialization value.
+- Misc: Changed the internal name formatting of child windows identifier to use slashes (instead of dots) as separator, more readable.
+- Misc: Fixed compilation with `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` defined.
+- Misc: Marked all format+va_list functions with format attribute so GCC/Clang can warn about misuses.
+- Misc: Fixed compilation on NetBSD due to missing alloca.h (#1319) [@RyuKojiro]
+- Misc: Improved warnings compilation for newer versions of Clang. (#1324) (@waywardmonkeys)
+- Misc: Added `io.WantMoveMouse flags` (from Nav branch) and honored in Examples applications. Currently unused but trying to spread Examples applications code that supports it.
+- Misc: Added `IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS` support in imconfig.h to allow user reimplementing the `ImFormatString()` functions e.g. to use stb_printf(). (#1038)
+- Misc: [Windows] Fixed default Win32 `SetClipboardText()` handler leaving the Win32 clipboard handler unclosed on failure. [@pdoane]
+- Style: Added `ImGuiStyle::ScaleAllSizes(float)` helper to make it easier to have application transition e.g. from low to high DPI with a matching style.
+- Metrics: Draw window bounding boxes when hovering Pos/Size; List all draw layers; Trimming empty commands like Render() does.
+- Examples: OpenGL3: Save and restore sampler state. (#1145) [@nlguillemot]
+- Examples: OpenGL2, OpenGL3: Save and restore polygon mode. (#1307) [@JJscott]
+- Examples: DirectX11: Allow creating device with feature level 10 since we don't really need much for that example. (#1333)
+- Examples: DirectX9/10/12: Using the Win32 SetCapture/ReleaseCapture API to read mouse coordinates when they are out of bounds. (#1375) [@Gargaj, @ocornut]
+- Tools: Fixed binary_to_compressed_c tool to return 0 when successful. (#1350) [@benvanik]
+- Internals: Exposed more helpers and unfinished features in imgui_internal.h. (use at your own risk!).
+- Internals: A bunch of internal refactoring, hopefully haven't broken anything! Merged a bunch of internal changes from the upcoming Navigation branch.
+- Various tweaks, fixes and documentation changes.
+
+Beta Navigation Branch:
+(Lots of work has been done toward merging the Beta Gamepad/Keyboard Navigation branch (#787) in master.)
+(Please note that this branch is always kept up to date with master. If you are using the navigation branch, some of the changes include:)
+- Nav: Added `#define IMGUI_HAS_NAV` in imgui.h to ease sharing code between both branches. (#787)
+- Nav: MainMenuBar now releases focus when user gets out of the menu layer. (#787)
+- Nav: When applying focus to a window with only menus, the menu layer is automatically activated. (#787)
+- Nav: Added `ImGuiNavInput_KeyMenu` (~Alt key) aside from ImGuiNavInput_PadMenu input as it is one differentiator of pad vs keyboard that was detrimental to the keyboard experience. Although isn't officially supported, it makes the current experience better. (#787)
+- Nav: Move requests now wrap vertically inside Menus and Popups. (#787)
+- Nav: Allow to collapse tree nodes with NavLeft and open them with NavRight. (#787, #1079).
+- Nav: It's now possible to navigate sibling of a menu-bar while navigating inside one of their child. If a Left<>Right navigation request fails to find a match we forward the request to the root menu. (#787, #126)
+- Nav: Fixed `SetItemDefaultFocus` from stealing default focus when we are initializing default focus for a menu bar layer. (#787)
+- Nav: Support for fall-back horizontal scrolling with PadLeft/PadRight (nb: fall-back scrolling is only used to navigate windows that have no interactive items). (#787)
+- Nav: Fixed tool-tip from being selectable in the window selection list. (#787)
+- Nav: `CollapsingHeader(bool*)` variant: fixed for `IsItemHovered()` not working properly in the nav branch. (#600, #787)
+- Nav: InputText: Fixed using Up/Down history callback feature when Nav is enabled. (#787)
+- Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787)
+- Nav: More consistently drawing a (thin) navigation rectangle hover filled frames such as tree nodes, collapsing header, menus. (#787)
+- Nav: Various internal refactoring.

+VERSION 1.51 (2017-08-24)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.51
+
+Breaking Changes:
+
+Work on dear imgui has been gradually resuming. It means that fixes and new features should be tackled at a faster rate than last year. However, in order to move forward with the library and get rid of some cruft, I have taken the liberty to be a little bit more aggressive than usual with API breaking changes. Read the details below and search for those names in your code! In the grand scheme of things, those changes are small and should not affect everyone, but this is technically our most aggressive release so far in term of API breakage. If you want to be extra forward-facing, you can enable `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h to disable the obsolete names/redirection.
+
+- Renamed `IsItemHoveredRect()` to `IsItemRectHovered()`. Kept inline redirection function (will obsolete).
+- Renamed `IsMouseHoveringWindow()` to `IsWindowRectHovered()` for consistency. Kept inline redirection function (will obsolete).
+- Renamed `IsMouseHoveringAnyWindow()` to `IsAnyWindowHovered()` for consistency. Kept inline redirection function (will obsolete).
+- Renamed `ImGuiCol_Columns***` enums to `ImGuiCol_Separator***`. Kept redirection enums (will obsolete).
+- Renamed `ImGuiSetCond***` types and enums to `ImGuiCond***`. Kept redirection enums (will obsolete).
+- Renamed `GetStyleColName()` to `GetStyleColorName()` for consistency. Unlikely to be used by end-user!
+- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
+- Marked the weird `IMGUI_ONCE_UPON_A_FRAME` helper macro as obsolete. Prefer using the more explicit `ImGuiOnceUponAFrame`.
+- Changed `ColorEdit4(const char* label, float col[4], bool show_alpha = true)` signature to `ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)`, where flags 0x01 is a safe no-op (hello dodgy backward compatibility!). The new `ColorEdit4`/`ColorPicker4` functions have lots of available flags! Check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
+- Changed signature of `ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)` to `ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))`. This function was rarely used and was very dodgy (no explicit ID!).
+- Changed `BeginPopupContextWindow(bool also_over_items=true, const char* str_id=NULL, int mouse_button=1)` signature to `(const char* str_id=NULL, int mouse_button=1, bool also_over_items=true)`. This is perhaps the most aggressive change in this update, but note that the majority of users relied on default parameters completely, so this will affect only a fraction of users of this already rarely used function.
+- Removed `IsPosHoveringAnyWindow()`, which was partly broken and misleading. In the vast majority of cases, people using that function wanted to use `io.WantCaptureMouse` flag. Replaced with IM_ASSERT + comment redirecting user to `io.WantCaptureMouse`. (#1237)
+- Removed the old `ValueColor()` helpers, they are equivalent to calling `Text(label)` + `SameLine()` + `ColorButton()`.
+- Removed `ColorEditMode()` and `ImGuiColorEditMode` type in favor of `ImGuiColorEditFlags` and parameters to the various Color*() functions. The `SetColorEditOptions()` function allows to initialize default but the user can still change them with right-click context menu. Commenting out your old call to `ColorEditMode()` may just be fine!
+
+Other Changes:
+
+- Added flags to `ColorEdit3()`, `ColorEdit4()`. The color edit widget now has a context-menu and access to the color picker. (#346)
+- Added flags to `ColorButton()`. (#346)
+- Added `ColorPicker3()`, `ColorPicker4()`. The API along with those of the updated `ColorEdit4()` was designed so you may use them in various situation and hopefully compose your own picker if required. There are a bunch of available flags, check the Demo window and comment for `ImGuiColorEditFlags_`. Some of the options it supports are: two color picker types (hue bar + sat/val rectangle, hue wheel + rotating sat/val triangle), display as u8 or float, lifting 0.0..1.0 constraints (currently rgba only), context menus, alpha bar, background checkerboard options, preview tooltip, basic revert. For simple use, calling the existing `ColorEdit4()` function as you did before will be enough, as you can now open the color picker from there. (#346) [@r-lyeh, @nem0, @thennequin, @dariomanesku and @ocornut]
+- Added `SetColorEditOptions()` to set default color options (e.g. if you want HSV over RGBA, float over u8, select a default picker mode etc. at startup time without a user intervention. Note that the user can still change options with the context menu unless disabled with `ImGuiColorFlags_NoOptions` or explicitly enforcing a display type/picker mode etc.).
+- Added user-facing `IsPopupOpen()` function. (#891) [@mkeeter]
+- Added `GetColorU32(u32)` variant that perform the style alpha multiply without a floating-point round trip, and helps makes code more consistent when using ImDrawList APIs.
+- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload.
+- Added `GetStyleColorVec4(ImGuiCol idx)` which is equivalent to accessing `ImGui::GetStyle().Colors[idx]` (aka return the raw style color without alpha alteration).
+- ImFontAtlas: Added `GlyphRangesBuilder` helper class, which makes it easier to build custom glyph ranges from your app/game localization data, or add into existing glyph ranges.
+- ImFontAtlas: Added `TexGlyphPadding` option. (#1282) [@jadwallis]
+- ImFontAtlas: Made it possible to override size of AddFontDefault() (even if it isn't really recommended!).
+- ImDrawList: Added `GetClipRectMin()`, `GetClipRectMax()` helpers.
+- Fixed Ini saving crash if the ImGuiWindowFlags_NoSavedSettings gets removed from a window after its creation (unlikely!). (#1000)
+- Fixed `PushID()`/`PopID()` from marking parent window as Accessed (which needlessly woke up the root "Debug" window when used outside of a regular window). (#747)
+- Fixed an assert when calling `CloseCurrentPopup()` twice in a row. [@nem0]
+- Window size can be loaded from .ini data even if ImGuiWindowFlags_NoResize flag is set. (#1048, #1056)
+- Columns: Added `SetColumnWidth()`. (#913) [@ggtucker]
+- Columns: Dragging a column preserve its width by default. (#913) [@ggtucker]
+- Columns: Fixed first column appearing wider than others. (#1266)
+- Columns: Fixed allocating space on the right-most side with the assumption of a vertical scrollbar. The space is only allocated when needed. (#125, #913, #893, #1138)
+- Columns: Fixed the right-most column from registering its content width to the parent window, which led to various issues when using auto-resizing window or e.g. horizonal scrolling. (#519, #125, #913)
+- Columns: Refactored some of the columns code internally toward a better API (not yet exposed) + minor optimizations. (#913) [@ggtucker, @ocornut]
+- Popups: Most popups windows can be moved by the user after appearing (if they don't have explicit positions provided by caller, or e.g. sub-menu popup). The previous restriction was totally arbitrary. (#1252)
+- Tooltip: `SetTooltip()` is expanded immediately into a window, honoring current font / styling setting. Add internal mechanism to override tooltips. (#862)
+- PlotHistogram: bars are drawn based on zero-line, so negative values are going under. (#828)
+- Scrolling: Fixed return values of `GetScrollMaxX()`, `GetScrollMaxY()` when both scrollbars were enabled. Tweak demo to display more data. (#1271) [@degracode]
+- Scrolling: Fixes for Vertical Scrollbar not automatically getting enabled if enabled Horizontal Scrollbar straddle the vertical limit. (#1271, #246)
+- Scrolling: `SetScrollHere()`, `SetScrollFromPosY()`: Fixed Y scroll aiming when Horizontal Scrollbar is enabled. (#665).
+- [Windows] Clipboard: Fixed not closing win32 clipboard on early open failure path. (#1264)
+- Removed an unnecessary dependency on int64_t which failed on some older compilers.
+- Demo: Rearranged everything under Widgets in a more consistent way.
+- Demo: Columns: Added Horizontal Scrolling demo. Tweaked another Columns demo. (#519, #125, #913)
+- Examples: OpenGL: Various makefiles for MINGW, Linux. (#1209, #1229, #1209) [@fr500, @acda]
+- Examples: Enabled vsync by default in example applications, so it doesn't confuse people that the sample run at 2000+ fps and waste an entire CPU. (#1213, #1151).
+- Various other small fixes, tweaks, comments, optimizations.

+-----------------------------------------------------------------------
+
+VERSION 1.50 (2017-06-02)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.50
+
+Breaking Changes:
+
+ - Added a void* user_data parameter to Clipboard function handlers. (#875)
+ - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
+ - Renamed ImDrawList::PathFill() - rarely used directly - to ImDrawList::PathFillConvex() for clarity and consistency.
+ - Removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
+ - Style: style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
+ - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
+

+- SameLine() with explicit X position is relative to left of group/columns. (ref #746, #125, #630)
+- SliderInt(), SliderFloat() supports reverse direction (where v_min > v_max). (#854)
+- SliderInt(), SliderFloat() better support for when v_min==v_max. (#919)
+- SliderInt(), SliderFloat() enforces writing back value when interacting, to be consistent with other widgets. (#919)
+- SliderInt, SliderFloat(): Fixed edge case where style.GrabMinSize being bigger than slider width can lead to a division by zero. (#919)
+- Added IsRectVisible() variation with explicit start-end positions. (#768) [@thedmd]
+- Fixed TextUnformatted() clipping bug in the large-text path when horizontal scroll has been applied. (#692, #246)

+- EndGroup(): Made IsItemHovered() work when an item was activated within the group. (#849)
+- BulletText(): Fixed stopping to display formatted string after the '##' mark.
+- Closing the focused window restore focus to the first active root window in descending z-order .(part of #727)
+- Word-wrapping: Fixed a bug where we never wrapped after a 1 character word. [@sronsse]
+- Word-wrapping: Fixed TextWrapped() overriding wrap position if one is already set. (#690)
+- Word-wrapping: Fixed incorrect testing for negative wrap coordinates, they are perfectly legal. (#706)
+- ImGuiListClipper: fixed automatic-height calc path dumbly having user display element 0 twice. (#661, #716)
+- ImGuiListClipper: Fix to behave within column. (#661, #662, #716)
+- ImDrawList: Renamed ImDrawList::PathFill() to ImDrawList::PathFillConvex() for clarity. (BREAKING API)

+- Clarified asserts in CheckStacksSize() when there is a stack mismatch.
+- Context: Support for #define-ing GImGui and IMGUI_SET_CURRENT_CONTEXT_FUNC to enable custom thread-based hackery (#586)
+- Updated stb_truetype.h to 1.14 (added OTF support, removed warnings). (#883, #976)

+-----------------------------------------------------------------------
+
+VERSION 1.49 (2016-05-09)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.49
+
+Breaking Changes:
+
+- Renamed `SetNextTreeNodeOpened()` to `SetNextTreeNodeOpen()` for consistency, no redirection.
+- Removed confusing set of `GetInternalState()`, `GetInternalStateSize()`, `SetInternalState()` functions. Now using `CreateContext()`, `DestroyContext()`, `GetCurrentContext()`, `SetCurrentContext()`. If you were using multiple contexts the change should be obvious and trivial.
+- Obsoleted old signature of `CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false)`, as extra parameters were badly designed and rarely used. Most uses were using 1 parameter and shouldn't affect you. You can replace the "default_open = true" flag in new API with `CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen)`.
+- Changed `ImDrawList::PushClipRect(ImVec4 rect)` to `ImDraw::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false)`. Note that higher-level `ImGui::PushClipRect()` is preferable because it will clip at logic/widget level, whereas `ImDrawList::PushClipRect()` only affect your renderer.
+- Title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore (see #655). If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
+ This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color. (Or If this is confusing, just pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.)
+
+ ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col)
+ {
+ float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w));
+ float k = title_bg_col.w / new_a;
+ return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a);
+ }
+
+Other changes:
+
+- New version of ImGuiListClipper helper calculates item height automatically. See comments and demo code. (#662, #661, #660)
+- Added SetNextWindowSizeConstraints() to enable basic min/max and programmatic size constraints on window. Added demo. (#668)
+- Added PushClipRect()/PopClipRect() (previously part of imgui_internal.h). Changed ImDrawList::PushClipRect() prototype. (#610)
+- Added IsRootWindowOrAnyChildHovered() helper. (#615)
+- Added TreeNodeEx() functions. (#581, #600, #190)
+- Added ImGuiTreeNodeFlags_Selected flag to display treenode as "selected". (#581, #190)
+- Added ImGuiTreeNodeFlags_AllowOverlapMode flag. (#600)
+- Added ImGuiTreeNodeFlags_NoTreePushOnOpen flag (#590).
+- Added ImGuiTreeNodeFlags_NoAutoOpenOnLog flag (previously private).
+- Added ImGuiTreeNodeFlags_DefaultOpen flag (previously private).
+- Added ImGuiTreeNodeFlags_OpenOnDoubleClick flag.
+- Added ImGuiTreeNodeFlags_OpenOnArrow flag.
+- Added ImGuiTreeNodeFlags_Leaf flag, always opened, no arrow, for convenience. For simple use case prefer using TreeAdvanceToLabelPos()+Text().
+- Added ImGuiTreeNodeFlags_Bullet flag, to add a bullet to Leaf node or replace Arrow with a bullet.
+- Added TreeAdvanceToLabelPos(), GetTreeNodeToLabelSpacing() helpers. (#581, #324)
+- Added CreateContext()/DestroyContext()/GetCurrentContext()/SetCurrentContext(). Obsoleted nearly identical GetInternalState()/SetInternalState() functions. (#586, #269)
+- Added NewLine() to undo a SameLine() and as a shy reminder that horizontal layout support hasn't been implemented yet.
+- Added IsItemClicked() helper. (#581)
+- Added CollapsingHeader() variant with close button. (#600)
+- Fixed MenuBar missing lower border when borders are enabled.
+- InputText(): Fixed clipping of cursor rendering in case it gets out of the box (which can be forced w/ ImGuiInputTextFlags_NoHorizontalScroll. (#601)
+- Style: Changed default IndentSpacing from 22 to 21. (#581, #324)
+- Style: Fixed TitleBg/TitleBgActive color being rendered above WindowBg color, which was inconsistent and causing visual artefact. (#655)
+ This broke the meaning of TitleBg and TitleBgActive. Only affect values where Alpha<1.0f. Fixed default theme. Read comments in "API BREAKING CHANGES" section to convert.
+- Relative rendering of order of Child windows creation is preserved, to allow more control with overlapping childs. (#595)
+- Fixed GetWindowContentRegionMax() being off by ScrollbarSize amount when explicit SizeContents is set.
+- Indent(), Unindent(): optional non-default indenting width. (#324, #581)
+- Bullet(), BulletText(): Slightly bigger. Less polygons.
+- ButtonBehavior(): fixed subtle old bug when a repeating button would also return true on mouse release (barely noticeable unless RepeatRate is set to be very slow). (#656)
+- BeginMenu(): a menu that becomes disabled while open gets closed down, facilitate user's code. (#126)
+- BeginGroup(): fixed using within Columns set. (#630)
+- Fixed a lag in reading the currently hovered window when dragging a window. (#635)
+- Obsoleted 4 parameters version of CollapsingHeader(). Refactored code into TreeNodeBehavior. (#600, #579)
+- Scrollbar: minor fix for top-right rounding of scrollbar background when window has menubar but no title bar.
+- MenuItem(): checkmark render in disabled color when menu item is disabled.
+- Fixed clipping rectangle floating point representation to ensure renderer-side float point operations yield correct results in typical DirectX/GL settings. (#582, 597)
+- Fixed GetFrontMostModalRootWindow(), fixing missing fade-out when a combo pop was used stacked over a modal window. (#604)
+- ImDrawList: Added AddQuad(), AddQuadFilled() helpers.
+- ImDrawList: AddText() refactor, moving some code to ImFont, reserving less unused vertices when large vertical clipping occurs.
+- ImFont: Added RenderChar() helper.
+- ImFont: Added AddRemapChar() helper. (#609)
+- ImFontConfig: Clarified persistence requirement of GlyphRanges array. (#651)
+- ImGuiStorage: Added bool helper functions for completeness.
+- AddFontFromMemoryCompressedTTF(): Fix font config propagation. (#587)
+- Renamed majority of use of the word "opened" to "open" for clarity. Renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(). (#625, #579)
+- Examples: OpenGL3: Saving/restoring glActiveTexture() state. (#602)
+- Examples: DirectX9: save/restore all device state.
+- Examples: DirectX9: Removed dependency on d3dx9.h, d3dx9.lib, dxguid.lib so it can be used in a DirectXMath.h only environment. (#611)
+- Examples: DirectX10/X11: Apply depth-stencil state (no use of depth buffer). (#640, #636)
+- Examples: DirectX11/X11: Added comments on removing dependency on D3DCompiler. (#638)
+- Examples: SDL: Initialize video+timer subsystem only.
+- Examples: Apple/iOS: lowered xcode project deployment target from 10.7 to 10.11. (#598, #575)

+-----------------------------------------------------------------------
+
+VERSION 1.48 (2016-04-09)
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.48
+
+Breaking Changes:
+
+- Consistently honoring exact width passed to PushItemWidth() (when positive), previously it would add extra FramePadding.x*2 over that width. Some hand-tuned layout may be affected slightly. (#346)
+- Style: removed `style.WindowFillAlphaDefault` which was confusing and redundant, baked alpha into `ImGuiCol_WindowBg` color. If you had a custom WindowBg color but didn't change WindowFillAlphaDefault, multiply WindowBg alpha component by 0.7. Renamed `ImGuiCol_TooltipBg` to `ImGuiCol_PopupBG`, applies to other types of popups. `bg_alpha` parameter of 5-parameters version of Begin() is an override. (#337)
+- InputText(): Added BufTextLen field in ImGuiTextEditCallbackData. Requesting user to update it if the buffer is modified in the callback. Added a temporary length-check assert to minimize panic for the 3 people using the callback. (#541)
+- Renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). (#340)
+
+Other Changes:
+
+- Consistently honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. Some hand-tuned layout may be affected slightly. (#346)
+- Fixed clipping of child windows within parent not taking account of child outer clipping boundaries (including scrollbar, etc.). (#506)
+- TextUnformatted(): Fixed rare crash bug with large blurb of text (2k+) not finished with a '\n' and fully above the clipping Y line. (#535)
+- IO: Added 'KeySuper' field to hold Cmd keyboard modifiers for OS X. Updated all examples accordingly. (#473)
+- Added ImGuiWindowFlags_ForceVerticalScrollbar, ImGuiWindowFlags_ForceHorizontalScrollbar flags. (#476)
+- Added IM_COL32 macros to generate a U32 packed color, convenient for direct use of ImDrawList api. (#346)
+- Added GetFontTexUvWhitePixel() helper, convenient for direct use of ImDrawList api.
+- Selectable(): Added ImGuiSelectableFlags_AllowDoubleClick flag to allow user reacting on double-click. (@zapolnov) (#516)
+- Begin(): made the close button explicitly set the boolean to false instead of toggling it. (#499)
+- BeginChild()/EndChild(): fixed incorrect layout to allow widgets submitted after an auto-fitted child window. (#540)
+- BeginChild(): Added ImGuiWindowFlags_AlwaysUseWindowPadding flag to ensure non-bordered child window uses window padding. (#462)
+- Fixed InputTextMultiLine(), ListBox(), BeginChildFrame(), ProgressBar(): outer frame not honoring bordering. (#462, #503)
+- Fixed Image(), ImageButtion() rendering a rectangle 1 px too large on each axis. (#457)
+- SetItemAllowOverlap(): Promoted from imgui_internal.h to public imgui.h api. (#517)
+- Combo(): Right-most button stays highlighted when popup is open.
+- Combo(): Display popup above if there's isn't enough space below / or select largest side. (#505)
+- DragFloat(), SliderFloat(), InputFloat(): fixed cases of erroneously returning true repeatedly after a text input modification (e.g. "0.0" --> "0.000" would keep returning true). (#564)
+- DragFloat(): Always apply value when mouse is held/widget active, so that an always-reseting variable (e.g. non saved local) can be passed.
+- InputText(): OS X friendly behaviors: Word movement uses Alt key; Shortcuts uses Cmd key; Double-clicking text select a single word; Jumping to next word sets cursor to end of current word instead of beginning of current word. (@zhiayang), (#473)
+- InputText(): Added BufTextLen in ImGuiTextEditCallbackData. Requesting user to maintain it if buffer is modified. Zero-ing structure properly before use. (#541)
+- CheckboxFlags(): Added support for testing/setting multiple flags at the same time. (@DMartinek) (#555)
+- TreeNode(), CollapsingHeader() fixed not being able to use "##" sequence in a formatted label.
+- ColorEdit4(): Empty label doesn't add InnerSpacing.x, matching behavior of other widgets. (#346)
+- ColorEdit4(): Removed unnecessary calls to scanf() when idle in hexadecimal edit mode.
+- BeginPopupContextItem(), BeginPopupContextWindow(): added early out optimization.
+- CaptureKeyboardFromApp() / CaptureMouseFromApp(): added argument to allow clearing the capture flag. (#533)
+- ImDrawList: Fixed index-overflow check broken by AddText() casting current index back to ImDrawIdx. (#514)
+- ImDrawList: Fixed incorrect removal of trailing draw command if it is a callback command.
+- ImDrawList: Allow windows with only a callback only to be functional. (#524)
+- ImDrawList: Fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. (#457)
+- ImDrawList: Fixed ImDrawList::AddCircle() to fit precisely within bounding box like AddCircleFilled() and AddRectFilled(). (#457)
+- ImDrawList: AddCircle(), AddRect() takes optional thickness parameter.
+- ImDrawList: Added AddTriangle().
+- ImDrawList: Added PrimQuadUV() helper to ease custom rendering of textured quads (require primitive reserve).
+- ImDrawList: Allow AddText(ImFont\* font, float font_size, ...) variant to take NULL/0.0f as default.
+- ImFontAtlas: heuristic increase default texture width up for large number of glyphs. (#491)

+
+Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).
+
+Dear ImGui is designed to enable fast iterations and to empower programmers to create content creation tools and visualization / debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries.
+
+Dear ImGui is particularly suited to integration in games engine (for tooling), realtime 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard.
+
+Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine:
+- imgui.cpp
+- imgui.h
+- imgui_demo.cpp
+- imgui_draw.cpp
+- imgui_internal.h
+- imconfig.h (empty by default, user-editable)
+- stb_rect_pack.h
+- stb_textedit.h
+- stb_truetype.h
+
+No specific build process is required. You can add the .cpp files to your project or #include them from an existing file.
+
+### Usage
+
+Your code passes mouse/keyboard/gamepad inputs and settings to Dear ImGui (see example applications for more details). After Dear ImGui is setup, you can use it from \_anywhere\_ in your program loop:
+
+Code:
+```cpp
+ImGui::Text("Hello, world %d", 123);
+if (ImGui::Button("Save"))
+{
+ // do stuff
+}
+ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
+ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
+```
+Result:
+<br>
+<br>_(settings: Dark style (left), Light style (right) / Font: Roboto-Medium, 16px / Rounding: 5)_
+
+Code:
+```cpp
+// Create a window called "My First Tool", with a menu bar.
+ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
+if (ImGui::BeginMenuBar())
+{
+ if (ImGui::BeginMenu("File"))
+ {
+ if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
+ if (ImGui::MenuItem("Save", "Ctrl+S")) { /* Do stuff */ }
+ if (ImGui::MenuItem("Close", "Ctrl+W")) { my_tool_active = false; }
+ ImGui::EndMenu();
+ }
+ ImGui::EndMenuBar();
+}
+
+// Edit a color (stored as ~4 floats)
+ImGui::ColorEdit4("Color", my_color);
+
+// Plot some values
+const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f };
+ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values));
+
+// Display contents in a scrolling region
+ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
+ImGui::BeginChild("Scrolling");
+for (int n = 0; n < 50; n++)
+ ImGui::Text("%04d: Some text", n);
+ImGui::EndChild();
+ImGui::End();
+```
+Result:
+<br>
+
+### How it works
+
+Check out the References section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize state duplication, state synchronization and state storage from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces.
+
+Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes is typically very small. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase.
+
+_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
+
+Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc.
+
+Demo Binaries
+-------------
+
+You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
+- [imgui-demo-binaries-20180407.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20180407.zip) (Windows binaries, Dear ImGui 1.60 built 2018/04/07, 5 executables)
+
+The demo applications are unfortunately not yet DPI aware so expect some blurryness on a 4K screen. For DPI awareness you can load/reload your font at different scale, and scale your Style with `style.ScaleAllSizes()`.
+
+Bindings
+--------
+
+Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer and at ease with those concepts, it should take you less than an hour to integrate Dear ImGui in your custom engine, but make sure to spend time reading the FAQ, the comments and other documentation!
+
+_NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

+
+Frequently Asked Question (FAQ)
+-------------------------------
+
+<b>Where is the documentation?</b>
+
+- The documentation is at the top of imgui.cpp + effectively imgui.h.
+- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output.
+- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder.
+- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
+
+<b>Which version should I get?</b>
+
+I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
+
+<b>Who uses Dear ImGui?</b>
+
+See the [Software using dear imgui page](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) for an (incomplete) list of games/software which are publicly known to use dear imgui. Please add yours if you can!
+
+<b>Why the odd dual naming, "dear imgui" vs "ImGui"?</b>
+
+The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.
+
+<b>How can I tell whether to dispatch mouse/keyboard to imgui or to my application?</b>
+<br><b>How can I display an image? What is ImTextureID, how does it works?</b>
+<br><b>How can I have multiple widgets with the same label or without a label? A primer on labels and the ID Stack.</b>
+<br><b>How can I load a different font than the default?</b>
+<br><b>How can I easily use icons in my application?</b>
+<br><b>How can I load multiple fonts?</b>
+<br><b>How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?</b>
+<br><b>How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API)</b>
+<br><b>I integrated Dear ImGui in my engine and the text or lines are blurry..</b>
+<br><b>I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around..</b>
+<br><b>How can I help?</b>
+
+See the FAQ in imgui.cpp for answers.
+
+<b>How do you use Dear ImGui on a platform that may not have a mouse or keyboard?</b>
+
+You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).
+
+You can share your computer mouse seamlessy with your console/tablet/phone using [Synergy](http://synergy-project.org). This is the prefered solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC using Synergy 1.x. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui).
+
+For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimising for screen real-estate and precision.
+
+<b>Can you create elaborate/serious tools with Dear ImGui?</b>
+
+Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
+
+Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
+
+<b>Can you reskin the look of Dear ImGui?</b>
+
+You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):
+
+
+
+<b>Why using C++ (as opposed to C)?</b>
+
+Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
+
+There is an reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Links](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to other languages.

The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com).
+
+I first discovered imgui principles at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple imgui implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it.

+ISSUES & TODO LIST
+
+Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues/XXXX
+The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
+It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
+
+ - doc/test: add a proper documentation+regression testing system (#435)
+ - doc/test: checklist app to verify binding/integration of imgui (test inputs, rendering, callback, etc.).
+ - doc/tips: tips of the day: website? applet in imgui_club?
+ - project: folder or separate repository with maintained helpers (e.g. imgui_memory_editor.h, imgui_stl.h, maybe imgui_dock would be there?)
+
+ - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
+ - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
+ - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
+ - window: allow resizing of child windows (possibly given min/max for each axis?.)
+ - window: background options for child windows, border option (disable rounding).
+ - window: resizing from any sides? done. > need backends to honor mouse cursors properly. (#822)
+ - window: resize from borders: support some form of outer padding to make it easier to grab borders. (#822)
+ - window: begin with *p_open == false should return false.
+ - window: get size/pos helpers given names (see discussion in #249)
+ - window: a collapsed window can be stuck behind the main menu bar?
+ - window: when window is very small, prioritize resize button over close button.
+ - window: detect extra End() call that pop the "Debug" window out and assert at End() call site instead of at end of frame.
+ - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.
+ - window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
+ - window: expose contents size. (#1045)
+ - window: GetWindowSize() returns (0,0) when not calculated? (#1045)
+ - window: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
+!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
+ - scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
+
+ - drawdata: make it easy to clone (or swap?) a ImDrawData so user can easily save that data if they use threaded renderering.
+ - drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
+ - drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
+ - drawlist: primtiives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api
+ - drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
+ - drawlist: non-AA strokes have gaps between points (#593, #288), especially RenderCheckmark().
+ - drawlist: would be good to be able to deep copy a draw list (ImVector= op?).
+ - drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
+
+ - main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them.
+ - main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
+ - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
+ - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
+ - main: rename the main "Debug" window to avoid ID collision with user who may want to use "Debug" with specific flags.
+
+ - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
+ - widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
+ - widgets: add visauls for Disabled/ReadOnly mode and expose publicly (#211)
+ - widgets: add always-allow-overlap mode.
+ - widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
+ - widgets: activate by identifier (trigger button, focus given id)
+
+ - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile.
+ - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
+ - input text: expose CursorPos in char filter event (#816)
+ - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active.
+ - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
+ - input text: way to dynamically grow the buffer without forcing the user to initially allocate for worse case, e.g. more natural std::string (follow up on #200)
+ - input text: hover tooltip could show unclamped text
+ - input text: option to Tab after an Enter validation.
+ - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
+ - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
+ - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
+ - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependant). actually a very old bug but no one appears to have noticed it.
+ - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
+ - input text multi-line: support for cut/paste without selection (cut/paste the current line)
+ - input text multi-line: line numbers? status bar? (follow up on #200)
+ - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
+ - input text multi-line: better horizontal scrolling support (#383, #1224)
+ - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
+ - input number: optional range min/max for Input*() functions
+ - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
+ - input number: use mouse wheel to step up/down
+ - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
+
+ - layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
+ - layout: generalization of the above: a concept equivalent to word processor ruler tab stop ~ mini columns (position in X, no clipping implied) (vaguely relate to #267, #395, also what is used internally for menu items)
+ - layout: horizontal layout helper (#97)
+ - layout: horizontal flow until no space left (#404)
+ - layout: more generic alignment state (left/right/centered) for single items?
+ - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
+ - layout: BeginGroup() needs a border option. (~#1496)
+ - layout: vertical alignement of mixed height items (e.g. buttons) within a same line (#1284)
+
+ - columns: sizing policy (e.g. for each column: fixed size, %, fill, distribute default size among fills) (#513, #125)
+ - columns: add a conditional parameter to SetColumnOffset() (#513, #125)
+ - columns: headers. reorderable. (#513, #125)
+ - columns: optional sorting modifiers (up/down), sort list so sorting can be done multi-critera. notify user when sort order changed.
+ - columns: option to alternate background colors on odd/even scanlines.
+ - columns: allow columns to recurse.
+ - columns: allow a same columns set to be interrupted by e.g. CollapsingHeader and resume with columns in sync when moving them.
+ - columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125)
+ - columns: flag to add horizontal separator above/below?
+ - columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets)
+
+!- color: the color conversion helpers/types are a mess and needs sorting out.
+ - color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
+ - coloredit: it is still somehow awkward to copy colors around (unless going through Hex mode).
+
+ - plot: full featured plot/graph api w/ scrolling, zooming etc. all bell & whistle. why not!
+ - plot: PlotLines() should use the polygon-stroke facilities, less verticles (currently issues with averaging normals)
+ - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
+ - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
+ - plot: option/feature: draw the zero line
+ - plot: option/feature: draw grid, vertical markers
+ - plot: option/feature: draw unit
+ - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
+
+ - clipper: ability to force display 1 item in the list would be convenient (for patterns where we need to set active id etc.)
+ - clipper: ability to disable the clipping through a simple flag/bool.
+ - clipper: ability to run without knowing full count in advance.
+
+ - splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
+
+ - dock: docking extension
+ - dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code.
+
+ - tabs: re-ordering, close buttons, context menu, persistent order (#261, #351)
+
+ - ext: stl-ish friendly extension (imgui_stl.h) that has wrapped for std::string, std::vector etc.
+
+ - button: provide a button that looks framed.
+ - image/image button: misalignment on padded/bordered button?
+ - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
+ - image button: not taking an explicit id is odd.
+ - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
+ - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
+ - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
+ - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
+ - slider: precision dragging
+ - slider: step option (#1183)
+ - knob: rotating knob widget (#942)
+ - slider & drag: int data passing through a float
+ - drag float: up/down axis
+ - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
+
+ - combo: use clipper: make it easier to disable clipper with a single flag.
+ - combo: flag for BeginCombo to not return true when unchanged (#1182)
+ - combo: a way/helper to customize the combo preview (#1658)
+ - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
+ - listbox: refactor and clean the begin/end api
+ - listbox: multiple selection.
+ - listbox: unselect option (#1208)
+ - listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (wip stash)
+ - listbox: user may want to initial scroll to focus on the one selected value?
+ - listbox: expose hovered item for a basic ListBox
+ - listbox: keyboard navigation.
+ - listbox: scrolling should track modified selection.
+
+!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
+ - popups: reopening context menu at new position should be the behavior by default? (equivalent to internal OpenPopupEx() with reopen_existing=true) (~#1497)
+ - popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
+ - popups: clicking outside (to close popup) and holding shouldn't drag window below.
+ - popups: add variant using global identifier similar to Begin/End (#402)
+ - popups: border options. richer api like BeginChild() perhaps? (#197)
+ - tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred direction" and may teleport when moving mouse.
+ - tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
+ - tooltip: allow tooltips with timers? or general timer policy? (instaneous vs timed)
+
+ - menus: calling BeginMenu() twice with a same name doesn't append as Begin() does for regular windows (#1207)
+ - menus: menu bars inside modals windows are acting weird.
+ - statusbar: add a per-window status bar helper similar to what menubar does.
+ - shortcuts: local-style shortcut api, e.g. parse "&Save"
+ - shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
+ - shortcuts: programmatically access shortcuts "Focus("&Save"))
+ - menus: menubars: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
+ - menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
+
+ - text: selectable text (for copy) as a generic feature (ItemFlags?)
+ - text: proper alignment options in imgui_internal.h
+ - text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
+ - text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
+ - text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
+
+ - tree node / optimization: avoid formatting when clipped.
+ - tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
+ - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
+ - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
+ - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
+ - tree node: tweak color scheme to distinguish headers from selected tree node (#581)
+ - tree node: leaf/non-leaf highlight mismatch.
+
+!- settings: expose enough to save/load .ini from RAM instead of fopen
+ - settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
+ - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
+ - stb: add defines to disable stb implementations
+
+!- style: better default styles. (#707)
+ - style: border types: out-screen, in-screen, etc. (#447)
+ - style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding.
+ - style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
+ - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
+ - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
+ - style: global scale setting.
+ - style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
+ - style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
+ - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
+ - style editor: color child window height expressed in multiple of line height.
+
+ - log: LogButtons() options for specifying depth and/or hiding depth slider
+ - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
+ - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
+ - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
+
+ - filters: set a current filter that tree node can automatically query to hide themselves
+ - filters: handle wildcards (with implicit leading/trailing *), regexps
+ - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
+
+ - drag and drop: add demo. (#143, #479)
+ - drag and drop: allow using with other mouse buttons (where activeid won't be set). (#1637)
+ - drag and drop: test with reordering nodes (in a list, or a tree node). (#143)
+ - drag and drop: test integrating with os drag and drop.
+ - node/graph editor (#306)
+ - pie menus patterns (#434)
+ - markup: simple markup language for color change? (#902)
+
+!- font: need handling of missing glyphs by not packing/rasterizing glyph 0 of a given font.
+ - font: MergeMode: flags to select overwriting or not.
+ - font: MergeMode: duplicate glyphs are stored in the atlas texture which is suboptimal.
+ - font: better vertical centering (based e.g on height of lowercase 'x'?). currently Roboto-Medium size 16 px isn't currently centered. (#1619)
+ - font: free the Alpha buffer if user only requested RGBA.
+!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
+ - font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
+ - font: finish CustomRectRegister() to allow mapping unicode codepoint to custom texture data
+ - font: PushFontSize API (#1018)
+ - font/atlas: incremental updates
+ - font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
+ - font/atlas: allow user to submit its own primitive to be rectpacked, and allow to map them on a Unicode point.
+ - font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
+ - font/text: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
+ - font: imgui_freetype.h alternative renderer (#618)
+ - font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct).
+ - font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
+ - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
+ - font: fix AddRemapChar() to work before font has been built.
+ - font: (api breaking) removed "TTF" from symbol names. also because it now supports OTF.
+
+ - nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
+ - nav: allow input system to be be more tolerant of io.DeltaTime=0.0f
+ - nav: ESC on a flattened child
+ - nav: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
+ - nav: menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
+ - nav: menus: allow pressing Menu to leave a sub-menu.
+ - nav: simulate right-click or context activation? (SHIFT+F10)
+ - nav: tabs should go through most/all widgets (in submission order?).
+ - nav: when CTRL-Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
+ - nav: cannot access menubar of a flattened child window with Alt/menu key (not a very common use case..).
+ - nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
+ - nav: when activating a button that changes label (without a static ID) or disappear, can we somehow automatically recover into a nearest highlight item?
+ - nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
+ - nav: configuration flag to disable global shortcuts (currently only CTRL-tab) ?
+ - focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
+ - focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
+ - focus: unable to use SetKeyboardFocusHere() on clipped widgets. (#787)
+
+ - inputs: we need an explicit flag about whether the imgui window is focused, to be able to distinguish focused key releases vs alt-tabbing all release behaviors.
+ - inputs: rework IO system to be able to pass actual ordered/timestamped events. use an event queue? (~#335, #71)
+ - inputs: support track pad style scrolling & slider edit.
+
+ - misc: idle refresh: expose cursor blink animation timer for backend to be able to lower framerate.
+ - misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
+ - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
+ - misc: fix for compilation settings where stdcall isn't the default (e.g. vectorcall) (#1230)
+ - misc: PushItemFlag(): add a flag to disable keyboard capture when used with mouse? (#1682)
+
+ - web/emscriptem: refactor some examples to facilitate integration with emscripten main loop system. (#1713, #336)
+ - web/emscriptem: tweak OpenGL renderers to support OpenGL ES. (#1713, #336)
+
+ - remote: make a system like RemoteImGui first-class citizen/project (#75)
+
+ - demo: add vertical separator demo
+ - demo: add virtual scrolling example?
+ - examples: directx9: save/restore device state more thoroughly.
+ - examples: window minimize, maximize (#583)
+ - examples: provide a zero-framerate/idle example.
+ - examples: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // the problem is that DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)
+ - optimization: replace vsnprintf with stb_printf? or enable the defines/infrastructure to allow it (#1038)
+ - optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
+ - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
+ - optimization: use another hash function than crc32, e.g. FNV1a
+ - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
+ - optimization: turn some the various stack vectors into statically-sized arrays

+Those are standalone ready-to-build applications to demonstrate Dear ImGui.
+Binaries of some of those demos: http://www.miracleworld.net/imgui/binaries
+
+Third party languages and frameworks bindings:
+ https://github.com/ocornut/imgui/wiki/Links
+(languages: C, C#, ChaiScript, D, Go, Haxe, Odin, Python, Rust, Lua, Pascal)
+(other frameworks: OpenGLES, FreeGlut, Cinder, Cocos2d-x, SFML, GML/GameMaker Studio, Irrlicht,
+ Ogre, OpenSceneGraph, openFrameworks, LOVE, NanoRT, Qt3d, SFML, Unreal Engine 4, etc.)
+(extras: RemoteImGui, ImWindow, imgui_wm, etc.)
+
+
+TL;DR;
+ - Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
+ - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
+ to your project and use them unmodified.
+ - To LEARN how to setup imgui, you may refer to 'opengl2_example' because is the simplest one to read.
+ However, do NOT USE the 'opengl2_example' if your code is using any modern GL3+ calls.
+ Mixing old fixed-pipeline OpenGL2 and modern OpenGL3+ is going to make everything more complicated.
+ Read comments below for details. If you are not sure, in doubt, use 'opengl3_example'.
+ - If you have your own engine, you probably want to read a few of the examples first then adapt it to
+ your engine. Please note that if your engine is based on OpenGL/DirectX you can perfectly use the
+ existing rendering backends, don't feel forced to rewrite them with your own engine API, or you can
+ do that later when you already got things to work.
+
+Dear ImGui is highly portable and only requires a few things to run and render.
+ - Providing mouse/keyboard inputs
+ - Load the font atlas texture into graphics memory
+ - Providing a render function to render indexed textured triangles
+ - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
+So this is essentially what those examples are doing + the obligatory cruft for portability.
+
+Unfortunately in 2018 it is still tedious to create and maintain portable build files using external
+libraries (the kind we're using here to create a window and render 3D triangles) without relying on
+third party software. For most examples here I choose to provide:
+ - Makefiles for Linux/OSX
+ - Batch files for Visual Studio 2008+
+ - A .sln project file for Visual Studio 2010+
+Please let me know if they don't work with your setup!
+You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
+directly with a command-line compiler.
+
+Dear ImGui has zero to one frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
+Consider that OS mouse cursors are typically drawn through a specific hardware accelerated route and may
+feel smoother than other GPU rendered contents. You may experiment with the io.MouseDrawCursor flag to
+request ImGui to draw a mouse cursor itself, to visualize the lag between a hardware cursor and a software
+cursor. It might be beneficial to the user experience to switch to a software rendered cursor when an
+interactive drag is in progress.
+Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering),
+leaving you with little option but sadness (Intel GPU drivers were reported as such).

+ This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter.

+# iOS / OSX example
+
+## Introduction
+
+This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/) to share mouse/keyboard on an iOS device.
+
+It is a rather complex and messy example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui. **The opengl3_example/ should also work on OS X and is much simpler.** This is an integration for iOS with Synergy.
+
+Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
+
+## How to Use on iOS
+
+* In Synergy, go to Preferences, and uncheck "Use SSL encryption"
+* Run the example app.
+* Tap the "servername" button in the corner
+* Enter the name or the IP of your synergy host
+* If you had previously connected to a server, you may need to kill and re-start the app.
+
+## How to Build on OSX
+
+* Make sure you have install `brew`, if not, please refer to [Homebrew Website](http://brew.sh)
+* Run the command: `brew install glfw3`
+* Double click `imguiex.xcodeproj` and select `imguiex-osx` scheme
+* Click `Run` button
+
+## Notes and TODOs
+
+Things that would be nice but I didn't get around to doing:
+
+* iOS software keyboard not supported for text inputs
+* iOS hardware (bluetooth) keyboards not supported
+* Graceful disconnect/reconnect from uSynergy.
+* Copy/Paste not well-supported
+
+## C++ on iOS / OSX
+
+ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
+
+Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
+
+In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.

+// ImGui Win32 + DirectX10 binding
+
+// Implemented features:
+// [X] User texture binding. Use 'ID3D10ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other back-ends.
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavEnableSetMousePos is set).
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
+// 2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
+// 2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.
+// 2017-10-23: Inputs: Using Win32 ::SetCapture/::GetCapture() to retrieve mouse positions outside the client area when dragging.
+// 2016-11-12: Inputs: Only call Win32 ::SetCursor(NULL) when io.MouseDrawCursor is set.
+// 2016-05-07: DirectX10: Disabling depth-write.

+// ImGui Win32 + DirectX11 binding
+
+// Implemented features:
+// [X] User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavEnableSetMousePos is set).
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
+// 2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
+// 2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.
+// 2017-10-23: Inputs: Using Win32 ::SetCapture/::GetCapture() to retrieve mouse positions outside the client area when dragging.
+// 2016-11-12: Inputs: Only call Win32 ::SetCursor(NULL) when io.MouseDrawCursor is set.
+// 2016-05-07: DirectX11: Disabling depth-write.

+// ImGui Win32 + DirectX12 binding
+// FIXME: 64-bit only for now! (Because sizeof(ImTextureId) == sizeof(void*))
+
+// Implemented features:
+// [X] User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.

+// ImGui Win32 + DirectX9 binding
+
+// Implemented features:
+// [X] User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavEnableSetMousePos is set).
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

+ *
+ * Successful creation does not change which context is current. Before you
+ * can use the newly created context, you need to
+ * [make it current](@ref context_current). For information about the `share`
+ * parameter, see @ref context_sharing.
+ *
+ * The created window, framebuffer and context may differ from what you
+ * requested, as not all parameters and hints are
+ * [hard constraints](@ref window_hints_hard). This includes the size of the
+ * window, especially for full screen windows. To query the actual attributes
+ * of the created window, framebuffer and context, see @ref
+ * glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
+ *
+ * To create a full screen window, you need to specify the monitor the window
+ * will cover. If no monitor is specified, the window will be windowed mode.
+ * Unless you have a way for the user to choose a specific monitor, it is
+ * recommended that you pick the primary monitor. For more information on how
+ * to query connected monitors, see @ref monitor_monitors.
+ *
+ * For full screen windows, the specified size becomes the resolution of the
+ * window's _desired video mode_. As long as a full screen window is not
+ * iconified, the supported video mode most closely matching the desired video
+ * mode is set for the specified monitor. For more information about full
+ * screen windows, including the creation of so called _windowed full screen_
+ * or _borderless full screen_ windows, see @ref window_windowed_full_screen.
+ *
+ * By default, newly created windows use the placement recommended by the
+ * window system. To create the window at a specific position, make it
+ * initially invisible using the [GLFW_VISIBLE](@ref window_hints_wnd) window
+ * hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
+ * it.
+ *
+ * As long as at least one full screen window is not iconified, the screensaver
+ * is prohibited from starting.
+ *

+best practice to call uSynergyUpdate from a background thread so it is responsive.
+
+Because uSynergy relies mostly on blocking calls it will mostly stay in thread sleep state
+waiting for system mutexes and won't eat much memory.

+// ImGui Marmalade binding with IwGx
+

+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.

+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_Marmalade_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

+// ImGui GLFW binding with OpenGL (legacy, fixed pipeline)
+// (GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+
+// Implemented features:
+// [X] User texture binding. Cast 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+
+// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
+// **Prefer using the code in the opengl3_example/ folder**
+// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
+// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
+// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
+// confuse your GPU driver.
+// The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-20: Inputs: Renamed GLFW callbacks exposed in .h to not include GL2 in their name.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplGlfwGL2_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-02-06: Inputs: Honoring the io.WantSetMousePos flag by repositioning the mouse (ImGuiConfigFlags_NavEnableSetMousePos is set).
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+// 2018-01-09: Misc: Renamed imgui_impl_glfw.* to imgui_impl_glfw_gl2.*.
+// 2017-09-01: OpenGL: Save and restore current polygon mode.
+// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
+// 2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
+// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL2_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
+// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
+// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+// 2017-09-01: OpenGL: Save and restore current polygon mode.
+// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
+// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
+// 2016-07-29: OpenGL: Explicitly setting GL_UNPACK_ROW_LENGTH to reduce issues because SDL changes it. (#752)

+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplSdlGL3_Init() so user can override the GLSL version e.g. "#version 150".
+// 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
+// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
+// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
+// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+// 2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150.
+// 2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
+// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+// 2017-05-01: OpenGL: Fixed save and restore of current blend func state.
+// 2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.
+// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
+// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

+// ImGui GLFW binding with Vulkan + shaders
+
+// Missing features:
+// [ ] User texture binding. Changes of ImTextureID aren't supported by this binding! See https://github.com/ocornut/imgui/pull/914
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 5 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXX_CreateFontsTexture(), ImGui_ImplXXXX_NewFrame(), ImGui_ImplXXXX_Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-20: Inputs: Renamed GLFW callbacks exposed in .h to not include Vulkan in their name.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplGlfwVulkan_Render() calls ImGui_ImplGlfwVulkan_RenderDrawData() itself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+// 2017-05-15: Vulkan: Fix scissor offset being negative. Fix new Vulkan validation warnings. Set required depth member for buffer image copy.
+// 2016-11-13: Vulkan: Fix validation layer warnings and errors and redeclare gl_PerVertex.
+// 2016-10-18: Vulkan: Add location decorators & change to use structs as in/out in glsl, update embedded spv (produced with glslangValidator -x). Null the released resources.
+// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
+// 2016-08-27: Vulkan: Fix Vulkan example for use when a depth buffer is active.

+ MISSION STATEMENT
+ =================
+
+ - Easy to use to create code-driven and data-driven tools
+ - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools
+ - Easy to hack and improve
+ - Minimize screen real-estate usage
+ - Minimize setup and maintenance
+ - Minimize state storage on user side
+ - Portable, minimize dependencies, run on target (consoles, phones, etc.)
+ - Efficient runtime and memory consumption (NB- we do allocate when "growing" content e.g. creating a window,
+ opening a tree node for the first time, etc. but a typical frame should not allocate anything)
+
+ Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
+ - Doesn't look fancy, doesn't animate
+ - Limited layout features, intricate layouts are typically crafted in code
+
+
+ END-USER GUIDE
+ ==============
+
+ - Double-click on title bar to collapse window.
+ - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().
+ - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).
+ - Click and drag on any empty space to move window.
+ - TAB/SHIFT+TAB to cycle through keyboard editable fields.
+ - CTRL+Click on a slider or drag box to input value as text.
+ - Use mouse wheel to scroll.
+ - Text editor:
+ - Hold SHIFT or use mouse to select text.
+ - CTRL+Left/Right to word jump.
+ - CTRL+Shift+Left/Right to select words.
+ - CTRL+A our Double-Click to select all.
+ - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/
+ - CTRL+Z,CTRL+Y to undo/redo.
+ - ESCAPE to revert text to its original value.
+ - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
+ - Controls are automatically adjusted for OSX to match standard OSX text editing operations.
+ - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.
+ - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://goo.gl/9LgVZW
+
+
+ PROGRAMMER GUIDE
+ ================
+
+ READ FIRST
+
+ - Read the FAQ below this section!
+ - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction
+ or destruction steps, less data retention on your side, less state duplication, less state synchronization, less bugs.
+ - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
+ - You can learn about immediate-mode gui principles at http://www.johno.se/book/imgui.html or watch http://mollyrocket.com/861
+
+ HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
+
+ - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
+ - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
+ If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
+ from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
+ likely be a comment about it. Please report any issue to the GitHub page!
+ - Try to keep your copy of dear imgui reasonably up to date.
+
+ GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
+
+ - Run and study the examples and demo to get acquainted with the library.
+ - Add the Dear ImGui source files to your projects, using your preferred build system.
+ It is recommended you build the .cpp files as part of your project and not as a library.
+ - You can later customize the imconfig.h file to tweak some compilation time behavior, such as integrating imgui types with your own maths types.
+ - You may be able to grab and copy a ready made imgui_impl_*** file from the examples/ folder.
+ - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
+
+ - Init: retrieve the ImGuiIO structure with ImGui::GetIO() and fill the fields marked 'Settings': at minimum you need to set io.DisplaySize
+ (application resolution). Later on you will fill your keyboard mapping, clipboard handlers, and other advanced features but for a basic
+ integration you don't need to worry about it all.
+ - Init: call io.Fonts->GetTexDataAsRGBA32(...), it will build the font atlas texture, then load the texture pixels into graphics memory.
+ - Every frame:
+ - In your main loop as early a possible, fill the IO fields marked 'Input' (e.g. mouse position, buttons, keyboard info, etc.)
+ - Call ImGui::NewFrame() to begin the frame
+ - You can use any ImGui function you want between NewFrame() and Render()
+ - Call ImGui::Render() as late as you can to end the frame and finalize render data. it will call your io.RenderDrawListFn handler.
+ (Even if you don't render, call Render() and ignore the callback, or call EndFrame() instead. Otherwhise some features will break)
+ - All rendering information are stored into command-lists until ImGui::Render() is called.
+ - Dear ImGui never touches or knows about your GPU state. the only function that knows about GPU is the RenderDrawListFn handler that you provide.
+ - Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" phases
+ of your own application.
+ - Refer to the examples applications in the examples/ folder for instruction on how to setup your code.
+ - A minimal application skeleton may be:
+
+ // Application init
+ ImGui::CreateContext();
+ ImGuiIO& io = ImGui::GetIO();
+ io.DisplaySize.x = 1920.0f;
+ io.DisplaySize.y = 1280.0f;
+ // TODO: Fill others settings of the io structure later.
+
+ // Load texture atlas (there is a default font so you don't need to care about choosing a font yet)
+ unsigned char* pixels;
+ int width, height;
+ io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height);
+ // TODO: At this points you've got the texture data and you need to upload that your your graphic system:
+ MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA)
+ // TODO: Store your texture pointer/identifier (whatever your engine uses) in 'io.Fonts->TexID'. This will be passed back to your via the renderer.
+ io.Fonts->TexID = (void*)texture;
+
+ // Application main loop
+ while (true)
+ {
+ // Setup low-level inputs (e.g. on Win32, GetKeyboardState(), or write to those fields from your Windows message loop handlers, etc.)
+ ImGuiIO& io = ImGui::GetIO();
+ io.DeltaTime = 1.0f/60.0f;
+ io.MousePos = mouse_pos;
+ io.MouseDown[0] = mouse_button_0;
+ io.MouseDown[1] = mouse_button_1;
+
+ // Call NewFrame(), after this point you can use ImGui::* functions anytime
+ ImGui::NewFrame();
+
+ // Most of your application code here
+ MyGameUpdate(); // may use any ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
+ MyGameRender(); // may use any ImGui functions as well!
+
+ // Render & swap video buffers
+ ImGui::Render();
+ MyImGuiRenderFunction(ImGui::GetDrawData());
+ SwapBuffers();
+ }
+
+ // Shutdown
+ ImGui::DestroyContext();
+
+
+ - A minimal render function skeleton may be:
+
+ void void MyRenderFunction(ImDrawData* draw_data)
+ {
+ // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
+ // TODO: Setup viewport, orthographic projection matrix
+ // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
+ for (int n = 0; n < draw_data->CmdListsCount; n++)
+ {
+ const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data; // vertex buffer generated by ImGui
+ const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data; // index buffer generated by ImGui
+ for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)
+ {
+ const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];
+ if (pcmd->UserCallback)
+ {
+ pcmd->UserCallback(cmd_list, pcmd);
+ }
+ else
+ {
+ // The texture for the draw call is specified by pcmd->TextureId.
+ // The vast majority of draw calls with use the imgui texture atlas, which value you have set yourself during initialization.
+ MyEngineBindTexture(pcmd->TextureId);
+
+ // We are using scissoring to clip some objects. All low-level graphics API supports it.
+ // If your engine doesn't support scissoring yet, you may ignore this at first. You will get some small glitches
+ // (some elements visible outside their bounds) but you can fix that once everywhere else works!
+ MyEngineScissor((int)pcmd->ClipRect.x, (int)pcmd->ClipRect.y, (int)(pcmd->ClipRect.z - pcmd->ClipRect.x), (int)(pcmd->ClipRect.w - pcmd->ClipRect.y));
+
+ // Render 'pcmd->ElemCount/3' indexed triangles.
+ // By default the indices ImDrawIdx are 16-bits, you can change them to 32-bits if your engine doesn't support 16-bits indices.
+ MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer, vtx_buffer);
+ }
+ idx_buffer += pcmd->ElemCount;
+ }
+ }
+ }
+
+ - The examples/ folders contains many functional implementation of the pseudo-code above.
+ - When calling NewFrame(), the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags are updated.
+ They tell you if ImGui intends to use your inputs. When a flag is set you want to hide the corresponding inputs from the rest of your application.
+ However, in both cases you need to pass on the inputs to imgui. Read the FAQ below for more information about those flags.
+ - Please read the FAQ above. Amusingly, it is called a FAQ because people frequently have the same issues!
+
+ USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS [BETA]
+
+ - The gamepad/keyboard navigation is in Beta. Ask questions and report issues at https://github.com/ocornut/imgui/issues/787
+ - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
+ - Gamepad:
+ - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
+ - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().
+ Note that io.NavInputs[] is cleared by EndFrame().
+ - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:
+ 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
+ - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
+ Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
+ - You can download PNG/PSD files depicting the gamepad controls for common controllers at: goo.gl/9LgVZW.
+ - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo
+ to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
+ - Keyboard:
+ - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
+ NewFrame() will automatically fill io.NavInputs[] based on your io.KeyDown[] + io.KeyMap[] arrays.
+ - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
+ will be set. For more advanced uses, you may want to read from:
+ - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
+ - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
+ - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
+ Please reach out if you think the game vs navigation input sharing could be improved.
+ - Mouse:
+ - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
+ - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
+ - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
+ Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.
+ When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
+ When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that.
+ (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!)
+ (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
+ to set a boolean to ignore your other external mouse positions until the external source is moved again.)
+
+
+ API BREAKING CHANGES
+ ====================
+
+ Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
+ Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
+ Also read releases logs https://github.com/ocornut/imgui/releases for more details.
+
+ - 2018/03/20 (1.60) - Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch).
+ - 2018/03/12 (1.60) - Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
+ - 2018/03/08 (1.60) - Changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
+ - 2018/03/03 (1.60) - Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
+ - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
+ - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
+ - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
+ - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
+ - removed Shutdown() function, as DestroyContext() serve this purpose.
+ - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwhise CreateContext() will create its own font atlas instance.
+ - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
+ - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
+ - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
+ - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
+ - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
+ - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
+ - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
+ - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
+ - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
+ - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
+ - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
+ - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
+ - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
+ - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
+ - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
+ - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
+ Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
+ - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
+ - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
+ - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
+ - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
+ - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
+ - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
+ - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
+ removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
+ - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
+ - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
+ - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
+ - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
+ - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
+ - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
+ - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
+ - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
+ - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
+ - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame.
+ - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
+ - 2017/08/13 (1.51) - renamed ImGuiCol_Columns*** to ImGuiCol_Separator***. Kept redirection enums (will obsolete).
+ - 2017/08/11 (1.51) - renamed ImGuiSetCond_*** types and flags to ImGuiCond_***. Kept redirection enums (will obsolete).
+ - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
+ - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
+ - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
+ - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))'
+ - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
+ - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
+ - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
+ - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
+ - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
+ - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
+ - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
+ - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
+ If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you.
+ However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
+ This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color.
+ ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col)
+ {
+ float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a;
+ return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a);
+ }
+ If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
+ - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
+ - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
+ - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
+ - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDraw::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
+ - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
+ - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
+ - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
+ - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
+ - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
+ - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
+ - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
+ - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
+ GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
+ GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
+ - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
+ - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
+ - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
+ - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
+ you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
+ - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
+ this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
+ - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
+ - the signature of the io.RenderDrawListsFn handler has changed!
+ old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
+ new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
+ argument: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
+ ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
+ ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
+ - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
+ - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
+ - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
+ - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
+ - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
+ - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
+ - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
+ - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry!
+ - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
+ - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
+ - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
+ - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
+ - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
+ - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
+ - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
+ - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
+ - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
+ - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
+ - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
+ - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
+ - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
+ - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
+ - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
+ - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
+ - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
+ - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
+ - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
+ - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
+ - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
+ (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
+ font init: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); <..Upload texture to GPU..>
+ became: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); <..Upload texture to GPU>; io.Fonts->TexId = YourTextureIdentifier;
+ you now more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs.
+ it is now recommended that you sample the font texture with bilinear interpolation.
+ (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID.
+ (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
+ (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets

+
+ FREQUENTLY ASKED QUESTIONS (FAQ), TIPS
+ ======================================
+
+ Q: How can I tell whether to dispatch mouse/keyboard to imgui or to my application?
+ A: You can read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags from the ImGuiIO structure.
+ - When 'io.WantCaptureMouse' is set, imgui wants to use your mouse state, and you may want to discard/hide the inputs from the rest of your application.
+ - When 'io.WantCaptureKeyboard' is set, imgui wants to use your keyboard state, and you may want to discard/hide the inputs from the rest of your application.
+ - When 'io.WantTextInput' is set to may want to notify your OS to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console OS).
+ Note: you should always pass your mouse/keyboard inputs to imgui, even when the io.WantCaptureXXX flag are set false.
+ This is because imgui needs to detect that you clicked in the void to unfocus its windows.
+ Note: The 'io.WantCaptureMouse' is more accurate that any attempt to "check if the mouse is hovering a window" (don't do that!).
+ It handle mouse dragging correctly (both dragging that started over your application or over an imgui window) and handle e.g. modal windows blocking inputs.
+ Those flags are updated by ImGui::NewFrame(). Preferably read the flags after calling NewFrame() if you can afford it, but reading them before is also
+ perfectly fine, as the bool toggle fairly rarely. If you have on a touch device, you might find use for an early call to NewFrameUpdateHoveredWindowAndCaptureFlags().
+ Note: Text input widget releases focus on "Return KeyDown", so the subsequent "Return KeyUp" event that your application receive will typically
+ have 'io.WantCaptureKeyboard=false'. Depending on your application logic it may or not be inconvenient. You might want to track which key-downs
+ were targetted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)
+
+ Q: How can I display an image? What is ImTextureID, how does it works?
+ A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function.
+ Dear ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry!
+ It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc.
+ At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render.
+ Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing.
+ (C++ tip: OpenGL uses integers to identify textures. You can safely store an integer into a void*, just cast it to void*, don't take it's address!)
+ To display a custom image/texture within an ImGui window, you may use ImGui::Image(), ImGui::ImageButton(), ImDrawList::AddImage() functions.
+ Dear ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use.
+ You may call ImGui::ShowMetricsWindow() to explore active draw lists and visualize/understand how the draw data is generated.
+ It is your responsibility to get textures uploaded to your GPU.
+
+ Q: How can I have multiple widgets with the same label or without a label?
+ A: A primer on labels and the ID Stack...
+
+ - Elements that are typically not clickable, such as Text() items don't need an ID.
+
+ - Interactive widgets require state to be carried over multiple frames (most typically Dear ImGui
+ often needs to remember what is the "active" widget). To do so they need a unique ID. Unique ID
+ are typically derived from a string label, an integer index or a pointer.
+
+ Button("OK"); // Label = "OK", ID = top of id stack + hash of "OK"
+ Button("Cancel"); // Label = "Cancel", ID = top of id stack + hash of "Cancel"
+
+ - ID are uniquely scoped within windows, tree nodes, etc. which all pushes to the ID stack. Having
+ two buttons labeled "OK" in different windows or different tree locations is fine.
+
+ - If you have a same ID twice in the same location, you'll have a conflict:
+
+ Button("OK");
+ Button("OK"); // ID collision! Interacting with either button will trigger the first one.
+
+ Fear not! this is easy to solve and there are many ways to solve it!
+
+ - Solving ID conflict in a simple/local context:
+ When passing a label you can optionally specify extra ID information within string itself.
+ Use "##" to pass a complement to the ID that won't be visible to the end-user.
+ This helps solving the simple collision cases when you know e.g. at compilation time which items
+ are going to be created:
+
+ Button("Play"); // Label = "Play", ID = top of id stack + hash of "Play"
+ Button("Play##foo1"); // Label = "Play", ID = top of id stack + hash of "Play##foo1" (different from above)
+ Button("Play##foo2"); // Label = "Play", ID = top of id stack + hash of "Play##foo2" (different from above)
+
+ - If you want to completely hide the label, but still need an ID:
+
+ Checkbox("##On", &b); // Label = "", ID = top of id stack + hash of "##On" (no label!)
+
+ - Occasionally/rarely you might want change a label while preserving a constant ID. This allows
+ you to animate labels. For example you may want to include varying information in a window title bar,
+ but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID:
+
+ Button("Hello###ID"; // Label = "Hello", ID = top of id stack + hash of "ID"
+ Button("World###ID"; // Label = "World", ID = top of id stack + hash of "ID" (same as above)
+
+ sprintf(buf, "My game (%f FPS)###MyGame", fps);
+ Begin(buf); // Variable label, ID = hash of "MyGame"
+
+ - Solving ID conflict in a more general manner:
+ Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts
+ within the same window. This is the most convenient way of distinguishing ID when iterating and
+ creating many UI elements programmatically.
+ You can push a pointer, a string or an integer value into the ID stack.
+ Remember that ID are formed from the concatenation of _everything_ in the ID stack!
+
+ for (int i = 0; i < 100; i++)
+ {
+ PushID(i);
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of integer + hash of "Click"
+ PopID();
+ }
+
+ for (int i = 0; i < 100; i++)
+ {
+ MyObject* obj = Objects[i];
+ PushID(obj);
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of pointer + hash of "Click"
+ PopID();
+ }
+
+ for (int i = 0; i < 100; i++)
+ {
+ MyObject* obj = Objects[i];
+ PushID(obj->Name);
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of string + hash of "Click"
+ PopID();
+ }
+
+ - More example showing that you can stack multiple prefixes into the ID stack:
+
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of "Click"
+ PushID("node");
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of "node" + hash of "Click"
+ PushID(my_ptr);
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of "node" + hash of ptr + hash of "Click"
+ PopID();
+ PopID();
+
+ - Tree nodes implicitly creates a scope for you by calling PushID().
+
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of "Click"
+ if (TreeNode("node"))
+ {
+ Button("Click"); // Label = "Click", ID = top of id stack + hash of "node" + hash of "Click"
+ TreePop();
+ }
+
+ - When working with trees, ID are used to preserve the open/close state of each tree node.
+ Depending on your use cases you may want to use strings, indices or pointers as ID.
+ e.g. when following a single pointer that may change over time, using a static string as ID
+ will preserve your node open/closed state when the targeted object change.
+ e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
+ node open/closed state differently. See what makes more sense in your situation!
+
+ Q: How can I load a different font than the default?
+ A: Use the font atlas to load the TTF/OTF file you want:
+ ImGuiIO& io = ImGui::GetIO();
+ io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
+ io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+ (default is ProggyClean.ttf, rendered at size 13, embedded in dear imgui's source code)
+
+ New programmers: remember that in C/C++ and most programming languages if you want to use a
+ backslash \ within a string literal, you need to write it double backslash "\\":
+ io.Fonts->AddFontFromFileTTF("MyDataFolder\MyFontFile.ttf", size_in_pixels); // WRONG (you are escape the M here!)
+ io.Fonts->AddFontFromFileTTF("MyDataFolder\\MyFontFile.ttf", size_in_pixels); // CORRECT
+ io.Fonts->AddFontFromFileTTF("MyDataFolder/MyFontFile.ttf", size_in_pixels); // ALSO CORRECT
+
+ Q: How can I easily use icons in my application?
+ A: The most convenient and practical way is to merge an icon font such as FontAwesome inside you
+ main font. Then you can refer to icons within your strings. Read 'How can I load multiple fonts?'
+ and the file 'misc/fonts/README.txt' for instructions and useful header files.
+
+ Q: How can I load multiple fonts?
+ A: Use the font atlas to pack them into a single texture:
+ (Read misc/fonts/README.txt and the code in ImFontAtlas for more details.)
+
+ ImGuiIO& io = ImGui::GetIO();
+ ImFont* font0 = io.Fonts->AddFontDefault();
+ ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
+ ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);
+ io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+ // the first loaded font gets used by default
+ // use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
+
+ // Options
+ ImFontConfig config;
+ config.OversampleH = 3;
+ config.OversampleV = 1;
+ config.GlyphOffset.y -= 2.0f; // Move everything by 2 pixels up
+ config.GlyphExtraSpacing.x = 1.0f; // Increase spacing between characters
+ io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config);
+
+ // Combine multiple fonts into one (e.g. for icon fonts)
+ ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
+ ImFontConfig config;
+ config.MergeMode = true;
+ io.Fonts->AddFontDefault();
+ io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); // Merge icon font
+ io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge japanese glyphs
+
+ Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
+ A: When loading a font, pass custom Unicode ranges to specify the glyphs to load.
+
+ // Add default Japanese ranges
+ io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
+
+ // Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
+ ImVector<ImWchar> ranges;
+ ImFontAtlas::GlyphRangesBuilder builder;
+ builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
+ builder.AddChar(0x7262); // Add a specific character
+ builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
+ builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
+ io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
+
+ All your strings needs to use UTF-8 encoding. In C++11 you can encode a string literal in UTF-8
+ by using the u8"hello" syntax. Specifying literal in your source code using a local code page
+ (such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
+ Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
+
+ Text input: it is up to your application to pass the right character code by calling
+ io.AddInputCharacter(). The applications in examples/ are doing that. For languages relying
+ on an Input Method Editor (IME), on Windows you can copy the Hwnd of your application in the
+ io.ImeWindowHandle field. The default implementation of io.ImeSetInputScreenPosFn() will set
+ your Microsoft IME position correctly.
+
+ Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API)
+ A: - You can create a dummy window. Call SetNextWindowBgAlpha(0.0f), call Begin() with NoTitleBar|NoResize|NoMove|NoScrollbar|NoSavedSettings|NoInputs flags.
+ Then you can retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
+ - You can call ImGui::GetOverlayDrawList() and use this draw list to display contents over every other imgui windows.
+ - You can create your own ImDrawList instance. You'll need to initialize them ImGui::GetDrawListSharedData(), or create your own ImDrawListSharedData.
+
+ Q: I integrated Dear ImGui in my engine and the text or lines are blurry..
+ A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f).
+ Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension.
+
+ Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around..
+ A: You are probably mishandling the clipping rectangles in your render function.
+ Rectangles provided by ImGui are defined as (x1=left,y1=top,x2=right,y2=bottom) and NOT as (x1,y1,width,height).
+
+ Q: How can I help?
+ A: - If you are experienced with Dear ImGui and C++, look at the github issues, or TODO.txt and see how you want/can help!
+ - Convince your company to fund development time! Individual users: you can also become a Patron (patreon.com/imgui) or donate on PayPal! See README.
+ - Disclose your usage of dear imgui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
+ You may post screenshot or links in the gallery threads (github.com/ocornut/imgui/issues/1269). Visuals are ideal as they inspire other programmers.
+ But even without visuals, disclosing your use of dear imgui help the library grow credibility, and help other teams and programmers with taking decisions.
+ - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on github or privately).
+
+ - tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window.
+ this is also useful to set yourself in the context of another window (to get/set other settings)
+ - tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug".
+ - tip: the ImGuiOnceUponAFrame helper will allow run the block of code only once a frame. You can use it to quickly add custom UI in the middle
+ of a deep nested inner loop in your code.
+ - tip: you can call Render() multiple times (e.g for VR renders).
+ - tip: call and read the ShowDemoWindow() code in imgui_demo.cpp for more example of how to use ImGui!

+// dear imgui, v1.60
+// (demo code)
+
+// Message to the person tempted to delete this file when integrating ImGui into their code base:
+// Don't do it! Do NOT remove this file from your project! It is useful reference code that you and other users will want to refer to.
+// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
+// During development, you can call ImGui::ShowDemoWindow() in your code to learn about various features of ImGui. Have it wired in a debug menu!
+// Removing this file from your project is hindering access to documentation for everyone in your team, likely leading you to poorer usage of the library.
+// Note that you can #define IMGUI_DISABLE_DEMO_WINDOWS in imconfig.h for the same effect.
+// If you want to link core ImGui in your final builds but not those demo windows, #define IMGUI_DISABLE_DEMO_WINDOWS in imconfig.h and those functions will be empty.
+// In other situation, when you have ImGui available you probably want this to be available for reference and execution.
+// Thank you,
+// -Your beloved friend, imgui_demo.cpp (that you won't delete)
+
+// Message to beginner C/C++ programmers. About the meaning of 'static': in this demo code, we frequently we use 'static' variables inside functions.
+// We do this as a way to gather code and data in the same place, just to make the demo code faster to read, faster to write, and use less code.
+// A static variable persist across calls, so it is essentially like a global variable but declared inside the scope of the function.
+// It also happens to be a convenient way of storing simple UI related information as long as your function doesn't need to be reentrant or used in threads.
+// This might be a pattern you occasionally want to use in your code, but most of the real data you would be editing is likely to be stored outside your function.

+// ImGui GLFW binding with OpenGL3 + shaders
+// (GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+// (GL3W is a helper library to access OpenGL functions since there is no standard header to access modern OpenGL functions easily. Alternatives are GLEW, Glad, etc.)
+
+// Implemented features:
+// [X] User texture binding. Cast 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+// [X] Gamepad navigation mapping. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
+// https://github.com/ocornut/imgui
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplGlfwGL3_Init() so user can override the GLSL version e.g. "#version 150".
+// 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context.
+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
+// 2018-02-20: Inputs: Renamed GLFW callbacks exposed in .h to not include GL3 in their name.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplGlfwGL3_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
+// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
+// 2018-01-25: Inputs: Honoring the io.WantSetMousePos flag by repositioning the mouse (ImGuiConfigFlags_NavEnableSetMousePos is set).
+// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
+// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
+// 2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150. (Also changed GL context from 3.3 to 3.2 in example's main.cpp)
+// 2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode.
+// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
+// 2017-05-01: OpenGL: Fixed save and restore of current blend function state.
+// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.
+// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.
+// 2016-04-30: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE.

+// (GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+// (GL3W is a helper library to access OpenGL functions since there is no standard header to access modern OpenGL functions easily. Alternatives are GLEW, Glad, etc.)
+
+// Implemented features:
+// [X] User texture binding. Cast 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
+// [X] Gamepad navigation mapping. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+
+// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
+// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
+// If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.

+The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer) that is used by default.
+We embed the font in source code so you can use Dear ImGui without any file system access.
+You may also load external .TTF/.OTF files.
+The files in this folder are suggested fonts, provided as a convenience.
+(Note: .OTF support in stb_truetype.h currently doesn't appear to load every font)
+
+Fonts are rasterized in a single texture at the time of calling either of io.Fonts.GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().

+
+---------------------------------------
+ USING ICONS
+---------------------------------------
+
+ Using an icon font (such as FontAwesome: http://fontawesome.io) is an easy and practical way to use icons in your ImGui application.
+ A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without
+ having to change fonts back and forth.
+
+ To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut:
+ https://github.com/juliettef/IconFontCppHeaders
+
+ The C++11 version of those files uses the u8"" utf-8 encoding syntax + \u
+ #define ICON_FA_SEARCH u8"\uf002"
+ The pre-C++11 version has the values directly encoded as utf-8:
+ #define ICON_FA_SEARCH "\xEF\x80\x82"
+
+ Example:
+
+ // Merge icons into default tool font
+ #include "IconsFontAwesome.h"
+ ImGuiIO& io = ImGui::GetIO();
+ io.Fonts->AddFontDefault();
+
+ ImFontConfig config;
+ config.MergeMode = true;
+ static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
+ io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
+
+ // Usage, e.g.
+ ImGui::Text("%s Search", ICON_FA_SEARCH);
+
+ See Links below for other icons fonts and related tools.
+
+
+---------------------------------------
+ FONTS LOADING INSTRUCTIONS
+---------------------------------------
+
+ Load default font with:
+
+ ImGuiIO& io = ImGui::GetIO();
+ io.Fonts->AddFontDefault();
+
+ Load .TTF/.OTF file with:
+
+ ImGuiIO& io = ImGui::GetIO();
+ io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+
+ For advanced options create a ImFontConfig structure and pass it to the AddFont function (it will be copied internally)
+
+ ImFontConfig config;
+ config.OversampleH = 3;
+ config.OversampleV = 1;
+ config.GlyphExtraSpacing.x = 1.0f;
+ io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
+
+ If you have very large number of glyphs or multiple fonts:
+
+ - Mind the fact that some graphics drivers have texture size limitation.
+ - Set io.Fonts.TexDesiredWidth to specify a texture width to minimize texture height (see comment in ImFontAtlas::Build function).
+ - Set io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight; to disable rounding the texture height to the next power of two.
+ - You may reduce oversampling, e.g. config.OversampleH = 2 or 1.
+ - Reduce glyphs ranges, consider calculating them based on your source data if this is possible.
+
+ Combine two fonts into one:
+
+ // Load a first font
+ io.Fonts->AddFontDefault();
+
+ // Add character ranges and merge into the previous font
+ // The ranges array is not copied by the AddFont* functions and is used lazily
+ // so ensure it is available for duration of font usage
+ static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // will not be copied by AddFont* so keep in scope.
+ ImFontConfig config;
+ config.MergeMode = true;
+ io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese());
+ io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges);
+
+ Add a fourth parameter to bake specific font ranges only:
+
+ // Basic Latin, Extended Latin
+ io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesDefault());
+
+ // Include full set of about 21000 CJK Unified Ideographs
+ io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
+
+ // Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
+ io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesChinese());
+
+ Offset font vertically by altering the io.Font->DisplayOffset value:
+
+ ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+ font->DisplayOffset.y = 1; // Render 1 pixel down
+
+
+---------------------------------------
+ FREETYPE RASTERIZER, SMALL FONT SIZES
+---------------------------------------
+
+ Dear Imgui uses stb_truetype.h to rasterize fonts (with optional oversampling).
+ This technique and implementation are not ideal for fonts rendered at _small sizes_, which may appear a little blurry.
+ There is an implementation of the ImFontAtlas builder using FreeType that you can use in the misc/freetype/ folder.
+
+ FreeType supports auto-hinting which tends to improve the readability of small fonts.
+ Note that this code currently creates textures that are unoptimally too large (could be fixed with some work)
+
+
+---------------------------------------
+ BUILDING CUSTOM GLYPH RANGES
+---------------------------------------
+
+ You can use the ImFontAtlas::GlyphRangesBuilder helper to create glyph ranges based on text input.
+ For exemple: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
+
+ ImVector<ImWchar> ranges;
+ ImFontAtlas::GlyphRangesBuilder builder;
+ builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
+ builder.AddChar(0x7262); // Add a specific character
+ builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
+ builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
+ io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
+
+
+---------------------------------------
+ REMAPPING CODEPOINTS
+---------------------------------------
+
+ All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese, or CP-1251 for Cyrillic) will NOT work!
+ In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
+ e.g.
+ u8"hello"
+ u8"こんにちは"
+ You may also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.
+
+
+---------------------------------------
+ EMBEDDING FONTS IN SOURCE CODE
+---------------------------------------
+
+ Compile and use 'binary_to_compressed_c.cpp' to create a compressed C style array that you can embed in source code.
+ See the documentation in binary_to_compressed_c.cpp for instruction on how to use the tool.
+ You may find a precompiled version binary_to_compressed_c.exe for Windows instead of demo binaries package (see README).
+ The tool optionally used Base85 encoding to reduce the size of _source code_ but the read-only arrays will be about 20% bigger.
+
+ Then load the font with:
+
+ ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
+
+ Or
+
+ ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);

+// ImGui - binary_to_compressed_c.cpp
+// Helper tool to turn a file into a C array, if you want to embed font data in your source code.
+
+// The data is first compressed with stb_compress() to reduce source code size,
+// then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
+// (If we used 32-bits constants it would require take 11 bytes of source code to encode 4 bytes, and be endianness dependent)
+// Note that even with compression, the output array is likely to be bigger than the binary file..
+// Load compressed TTF fonts with ImGui::GetIO().Fonts->AddFontFromMemoryCompressedTTF()
+
+// Build with, e.g:
+// # cl.exe binary_to_compressed_c.cpp
+// # gcc binary_to_compressed_c.cpp
+// You can also find a precompiled Windows binary in the binary/demo package available from https://github.com/ocornut/imgui
+
+// Usage:
+// binary_to_compressed_c.exe [-base85] [-nocompress] <inputfile> <symbolname>

+2. Add imgui_freetype.h/cpp alongside your imgui sources.
+3. Include imgui_freetype.h after imgui.h.
+4. Call ImGuiFreeType::BuildFontAtlas() *BEFORE* calling ImFontAtlas::GetTexDataAsRGBA32() or ImFontAtlas::Build() (so normal Build() won't be called):
+
+```cpp
+// See ImGuiFreeType::RasterizationFlags
+unsigned int flags = ImGuiFreeType::DisableHinting;
+ImGuiFreeType::BuildFontAtlas(io.Fonts, flags);
+io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
+```
+
+**Gamma Correct Blending**
+FreeType assumes blending in linear space rather than gamma space.
+See FreeType note for [FT_Render_Glyph](https://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Glyph).
+For correct results you need to be using sRGB and convert to linear space in the pixel shader output.
+The default imgui styles will be impacted by this change (alpha values will need tweaking).
+
+**Test code Usage**
+```cpp
+#include "misc/freetype/imgui_freetype.h"
+#include "misc/freetype/imgui_freetype.cpp"
+
+// Load various small fonts
+ImGuiIO& io = ImGui::GetIO();

+io.Fonts->AddFontFromFileTTF("../../misc/fonts/Cousine-Regular.ttf", 13.0f);
+io.Fonts->AddFontDefault();
+

+while (true)
+{

+```
+
+**Known issues**
+- Output texture has excessive resolution (lots of vertical waste).
+- FreeType's memory allocator is not overridden.
+- `cfg.OversampleH`, `OversampleV` are ignored (but perhaps not so necessary with this rasterizer).

+// stb_rect_pack.h - v0.11 - public domain - rectangle packing
+// Sean Barrett 2014
+//
+// Useful for e.g. packing rectangular textures into an atlas.
+// Does not do rotation.
+//
+// Not necessarily the awesomest packing method, but better than
+// the totally naive one in stb_truetype (which is primarily what
+// this is meant to replace).
+//
+// Has only had a few tests run, may have issues.
+//
+// More docs to come.
+//
+// No memory allocations; uses qsort() and assert() from stdlib.
+// Can override those by defining STBRP_SORT and STBRP_ASSERT.
+//
+// This library currently uses the Skyline Bottom-Left algorithm.
+//
+// Please note: better rectangle packers are welcome! Please
+// implement them to the same API, but with a different init
+// function.

+// Development of this library was sponsored by RAD Game Tools
+//
+// This C header file implements the guts of a multi-line text-editing
+// widget; you implement display, word-wrapping, and low-level string
+// insertion/deletion, and stb_textedit will map user inputs into
+// insertions & deletions, plus updates to the cursor position,
+// selection state, and undo state.
+//
+// It is intended for use in games and other systems that need to build
+// their own custom widgets and which do not have heavy text-editing
+// requirements (this library is not recommended for use for editing large
+// texts, as its performance does not scale and it has limited undo).
+//
+// Non-trivial behaviors are modelled after Windows text controls.

+// USAGE
+//
+// This file behaves differently depending on what symbols you define
+// before including it.
+//
+//
+// Header-file mode:
+//
+// If you do not define STB_TEXTEDIT_IMPLEMENTATION before including this,
+// it will operate in "header file" mode. In this mode, it declares a
+// single public symbol, STB_TexteditState, which encapsulates the current
+// state of a text widget (except for the string, which you will store
+// separately).
+//
+// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
+// primitive type that defines a single character (e.g. char, wchar_t, etc).
+//
+// To save space or increase undo-ability, you can optionally define the
+// following things that are used by the undo system:
+//
+// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position
+// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow
+// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer
+//
+// If you don't define these, they are set to permissive types and
+// moderate sizes. The undo system does no memory allocations, so
+// it grows STB_TexteditState by the worst-case storage which is (in bytes):
+//
+// [4 + sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT
+// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT
+//
+//
+// Implementation mode:
+//
+// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
+// will compile the implementation of the text edit widget, depending
+// on a large number of symbols which must be defined before the include.
+//
+// The implementation is defined only as static functions. You will then
+// need to provide your own APIs in the same file which will access the
+// static functions.
+//
+// The basic concept is that you provide a "string" object which
+// behaves like an array of characters. stb_textedit uses indices to
+// refer to positions in the string, implicitly representing positions
+// in the displayed textedit. This is true for both plain text and
+// rich text; even with rich text stb_truetype interacts with your
+// code as if there was an array of all the displayed characters.
+//
+// Symbols that must be the same in header-file and implementation mode:
+//
+// STB_TEXTEDIT_CHARTYPE the character type
+// STB_TEXTEDIT_POSITIONTYPE small type that a valid cursor position
+// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow
+// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer
+//
+// Symbols you must define for implementation mode:
+//
+// STB_TEXTEDIT_STRING the type of object representing a string being edited,
+// typically this is a wrapper object with other data you need
+//
+// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1))
+// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters
+// starting from character #n (see discussion below)
+// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character
+// to the xpos of the i+1'th char for a line of characters
+// starting at character #n (i.e. accounts for kerning
+// with previous char)
+// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character
+// (return type is int, -1 means not valid to insert)
+// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based
+// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize
+// as manually wordwrapping for end-of-line positioning
+//
+// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i
+// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
+//
+// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key
+//
+// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left
+// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right
+// STB_TEXTEDIT_K_UP keyboard input to move cursor up
+// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down
+// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME
+// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END
+// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME
+// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END
+// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor
+// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor
+// STB_TEXTEDIT_K_UNDO keyboard input to perform undo
+// STB_TEXTEDIT_K_REDO keyboard input to perform redo
+//
+// Optional:
+// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode
+// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'),
+// required for default WORDLEFT/WORDRIGHT handlers
+// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to
+// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to
+// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT
+// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT
+// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line
+// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line
+// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text
+// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text
+//
+// Todo:
+// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page
+// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page
+//
+// Keyboard input must be encoded as a single integer value; e.g. a character code
+// and some bitflags that represent shift states. to simplify the interface, SHIFT must
+// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
+// i.e. (STB_TEXTED_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
+//
+// You can encode other things, such as CONTROL or ALT, in additional bits, and
+// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
+// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
+// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
+// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
+// API below. The control keys will only match WM_KEYDOWN events because of the
+// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
+// bit so it only decodes WM_CHAR events.
+//
+// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
+// row of characters assuming they start on the i'th character--the width and
+// the height and the number of characters consumed. This allows this library
+// to traverse the entire layout incrementally. You need to compute word-wrapping
+// here.
+//
+// Each textfield keeps its own insert mode state, which is not how normal
+// applications work. To keep an app-wide insert mode, update/copy the
+// "insert_mode" field of STB_TexteditState before/after calling API functions.
+//
+// API
+//
+// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line)
+//
+// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
+// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)

+// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, int key)
+//
+// Each of these functions potentially updates the string and updates the
+// state.
+//
+// initialize_state:
+// set the textedit state to a known good default state when initially
+// constructing the textedit.
+//
+// click:
+// call this with the mouse x,y on a mouse down; it will update the cursor
+// and reset the selection start/end to the cursor point. the x,y must
+// be relative to the text widget, with (0,0) being the top left.
+//
+// drag:
+// call this with the mouse x,y on a mouse drag/up; it will update the
+// cursor and the selection end point
+//
+// cut:
+// call this to delete the current selection; returns true if there was
+// one. you should FIRST copy the current selection to the system paste buffer.
+// (To copy, just copy the current selection out of the string yourself.)
+//
+// paste:
+// call this to paste text at the current cursor point or over the current
+// selection if there is one.
+//
+// key:
+// call this for keyboard inputs sent to the textfield. you can use it
+// for "key down" events or for "translated" key events. if you need to
+// do both (as in Win32), or distinguish Unicode characters from control
+// inputs, set a high bit to distinguish the two; then you can define the
+// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
+// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
+// clear.
+//
+// When rendering, you can read the cursor position and selection state from
+// the STB_TexteditState.
+//
+//
+// Notes:
+//
+// This is designed to be usable in IMGUI, so it allows for the possibility of
+// running in an IMGUI that has NOT cached the multi-line layout. For this
+// reason, it provides an interface that is compatible with computing the
+// layout incrementally--we try to make sure we make as few passes through
+// as possible. (For example, to locate the mouse pointer in the text, we
+// could define functions that return the X and Y positions of characters
+// and binary search Y and then X, but if we're doing dynamic layout this
+// will run the layout algorithm many times, so instead we manually search
+// forward in one pass. Similar logic applies to e.g. up-arrow and
+// down-arrow movement.)
+//
+// If it's run in a widget that *has* cached the layout, then this is less
+// efficient, but it's not horrible on modern computers. But you wouldn't
+// want to edit million-line files with it.

+// USAGE
+//
+// Include this file in whatever places neeed to refer to it. In ONE C/C++
+// file, write:
+// #define STB_TRUETYPE_IMPLEMENTATION
+// before the #include of this file. This expands out the actual
+// implementation into that C/C++ file.
+//
+// To make the implementation private to the file that generates the implementation,
+// #define STBTT_STATIC
+//
+// Simple 3D API (don't ship this, but it's fine for tools and quick start)
+// stbtt_BakeFontBitmap() -- bake a font to a bitmap for use as texture
+// stbtt_GetBakedQuad() -- compute quad to draw for a given char
+//
+// Improved 3D API (more shippable):
+// #include "stb_rect_pack.h" -- optional, but you really want it
+// stbtt_PackBegin()
+// stbtt_PackSetOversampling() -- for improved quality on small fonts
+// stbtt_PackFontRanges() -- pack and renders
+// stbtt_PackEnd()
+// stbtt_GetPackedQuad()
+//
+// "Load" a font file from a memory buffer (you have to keep the buffer loaded)
+// stbtt_InitFont()
+// stbtt_GetFontOffsetForIndex() -- indexing for TTC font collections
+// stbtt_GetNumberOfFonts() -- number of fonts for TTC font collections
+//
+// Render a unicode codepoint to a bitmap
+// stbtt_GetCodepointBitmap() -- allocates and returns a bitmap
+// stbtt_MakeCodepointBitmap() -- renders into bitmap you provide
+// stbtt_GetCodepointBitmapBox() -- how big the bitmap must be
+//
+// Character advance/positioning
+// stbtt_GetCodepointHMetrics()
+// stbtt_GetFontVMetrics()
+// stbtt_GetFontVMetricsOS2()
+// stbtt_GetCodepointKernAdvance()
+//
+// Starting with version 1.06, the rasterizer was replaced with a new,
+// faster and generally-more-precise rasterizer. The new rasterizer more
+// accurately measures pixel coverage for anti-aliasing, except in the case
+// where multiple shapes overlap, in which case it overestimates the AA pixel
+// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
+// this turns out to be a problem, you can re-enable the old rasterizer with
+// #define STBTT_RASTERIZER_VERSION 1
+// which will incur about a 15% speed hit.
+//
+// ADDITIONAL DOCUMENTATION
+//
+// Immediately after this block comment are a series of sample programs.
+//
+// After the sample programs is the "header file" section. This section
+// includes documentation for each API function.
+//
+// Some important concepts to understand to use this library:
+//
+// Codepoint
+// Characters are defined by unicode codepoints, e.g. 65 is
+// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
+// the hiragana for "ma".
+//
+// Glyph
+// A visual character shape (every codepoint is rendered as
+// some glyph)
+//
+// Glyph index
+// A font-specific integer ID representing a glyph
+//
+// Baseline
+// Glyph shapes are defined relative to a baseline, which is the
+// bottom of uppercase characters. Characters extend both above
+// and below the baseline.
+//
+// Current Point
+// As you draw text to the screen, you keep track of a "current point"
+// which is the origin of each character. The current point's vertical
+// position is the baseline. Even "baked fonts" use this model.
+//
+// Vertical Font Metrics
+// The vertical qualities of the font, used to vertically position
+// and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+// Font Size in Pixels or Points
+// The preferred interface for specifying font sizes in stb_truetype
+// is to specify how tall the font's vertical extent should be in pixels.
+// If that sounds good enough, skip the next paragraph.
+//
+// Most font APIs instead use "points", which are a common typographic
+// measurement for describing font size, defined as 72 points per inch.
+// stb_truetype provides a point API for compatibility. However, true
+// "per inch" conventions don't make much sense on computer displays
+// since different monitors have different number of pixels per
+// inch. For example, Windows traditionally uses a convention that
+// there are 96 pixels per inch, thus making 'inch' measurements have
+// nothing to do with inches, and thus effectively defining a point to
+// be 1.333 pixels. Additionally, the TrueType font data provides
+// an explicit scale factor to scale a given font's glyphs to points,
+// but the author has observed that this scale factor is often wrong
+// for non-commercial fonts, thus making fonts scaled in points
+// according to the TrueType spec incoherently sized in practice.
+//
+// DETAILED USAGE:
+//
+// Scale:
+// Select how high you want the font to be, in points or pixels.
+// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
+// a scale factor SF that will be used by all other functions.
+//
+// Baseline:
+// You need to select a y-coordinate that is the baseline of where
+// your text will appear. Call GetFontBoundingBox to get the baseline-relative
+// bounding box for all characters. SF*-y0 will be the distance in pixels
+// that the worst-case character could extend above the baseline, so if
+// you want the top edge of characters to appear at the top of the
+// screen where y=0, then you would set the baseline to SF*-y0.
+//
+// Current point:
+// Set the current point where the first character will appear. The
+// first character could extend left of the current point; this is font
+// dependent. You can either choose a current point that is the leftmost
+// point and hope, or add some padding, or check the bounding box or
+// left-side-bearing of the first character to be displayed and set
+// the current point based on that.
+//
+// Displaying a character:
+// Compute the bounding box of the character. It will contain signed values
+// relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
+// then the character should be displayed in the rectangle from
+// <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
+//
+// Advancing for the next character:
+// Call GlyphHMetrics, and compute 'current_point += SF * advance'.
+//
+//
+// ADVANCED USAGE
+//
+// Quality:
+//
+// - Use the functions with Subpixel at the end to allow your characters
+// to have subpixel positioning. Since the font is anti-aliased, not
+// hinted, this is very import for quality. (This is not possible with
+// baked fonts.)
+//
+// - Kerning is now supported, and if you're supporting subpixel rendering
+// then kerning is worth using to give your text a polished look.
+//
+// Performance:
+//
+// - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+// if you don't do this, stb_truetype is forced to do the conversion on
+// every call.
+//
+// - There are a lot of memory allocations. We should modify it to take
+// a temp buffer and allocate from the temp buffer (without freeing),
+// should help performance a lot.
+//
+// NOTES
+//
+// The system uses the raw data found in the .ttf file without changing it
+// and without building auxiliary data structures. This is a bit inefficient
+// on little-endian systems (the data is big-endian), but assuming you're
+// caching the bitmaps or glyph shapes this shouldn't be a big deal.
+//
+// It appears to be very hard to programmatically determine what font a
+// given file is in a general way. I provide an API for this, but I don't
+// recommend it.
