dear imgui, v1.79
-----------------------------------------------------------------------
examples/README.txt
(This is the README file for the examples/ folder. See docs/ for more documentation)
-----------------------------------------------------------------------
Dear ImGui is highly portable and only requires a few things to run and render:
- Providing mouse/keyboard inputs
- Uploading 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.
- Optional (Advanced,Beta): platform window API to use multi-viewport.
This is essentially what the example bindings in this folder are providing + obligatory portability cruft.
It is important to understand the difference between the core Dear ImGui library (files in the root folder)
and examples bindings which we are describing here (examples/ folder).
You should be able to write bindings for pretty much any platform and any 3D graphics API. With some extra
effort you can even perform the rendering remotely, on a different machine than the one running the logic.
This folder contains two things:
- Example bindings for popular platforms/graphics API, which you can use as is or adapt for your own use.
They are the imgui_impl_XXXX files found in the examples/ folder.
- Example applications (standalone, ready-to-build) using the aforementioned bindings.
They are the in the XXXX_example/ sub-folders.
You can find binaries of some of those example applications at:
http://www.dearimgui.org/binaries
---------------------------------------
GETTING STARTED
---------------------------------------
- Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
Please read the comments and instruction at the top of each file.
Please read FAQ at http://www.dearimgui.org/faq
- If you are using of the backend provided here, you can add the imgui_impl_xxx.cpp/h files
to your project and use them unmodified. Each imgui_impl_xxxx.cpp comes with its own individual
Changelog at the top of the .cpp files, so if you want to update them later it will be easier to
catch up with what changed.
- Dear ImGui has no particular extra lag for most behaviors, e.g. the value of 'io.MousePos' provided in
NewFrame() will result at the time of EndFrame()/Render() in a moved windows rendered following that mouse
movement. At 60 FPS your experience should be pleasant.
However, consider that OS mouse cursors are typically drawn through a very specific hardware accelerated
path and will feel smoother than the majority of contents rendererd via regular graphics API (including,
but not limited to Dear ImGui windows). Because UI rendering and interaction happens on the same plane as
the mouse, that disconnect may be jarring to particularly sensitive users.
You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor
using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a
regularly rendered software cursor.
However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at
all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_
when an interactive drag is in progress.
Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings.
If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple
drawing a flat 2D shape directly under the mouse cursor.
---------------------------------------
EXAMPLE BINDINGS
---------------------------------------
Most the example bindings are split in 2 parts:
- The "Platform" bindings, in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.
Examples: Windows (imgui_impl_win32.cpp), GLFW (imgui_impl_glfw.cpp), SDL2 (imgui_impl_sdl.cpp), etc.
- The "Renderer" bindings, in charge of: creating the main font texture, rendering imgui draw data.
Examples: DirectX11 (imgui_impl_dx11.cpp), GL3 (imgui_impl_opengl3.cpp), Vulkan (imgui_impl_vulkan.cpp), etc.
- The example _applications_ usually combine 1 platform + 1 renderer binding to create a working program.
Examples: the example_win32_directx11/ application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp.
- Some bindings for higher level frameworks carry both "Platform" and "Renderer" parts in one file.
This is the case for Allegro 5 (imgui_impl_allegro5.cpp), Marmalade (imgui_impl_marmalade5.cpp).
- If you use your own engine, you may decide to use some of existing bindings and/or rewrite some using
your own API. As a recommendation, if you are new to Dear ImGui, try using the existing binding as-is
first, before moving on to rewrite some of the code. Although it is tempting to rewrite both of the
imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary!
In fact, if you are new to Dear ImGui, rewriting them will almost always be harder.
Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering
system layered over DirectX11.
Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer
using your own functions, etc.
Please consider using the bindings to the lower-level platform/graphics API as-is.
Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere.
Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)!
This is counter-intuitive, but this will get you running faster! Once you better understand how imgui
works and is bound, you can rewrite the code using your own systems.
- Road-map: Dear ImGui 1.80 (WIP currently in the "docking" branch) will allows imgui windows to be
seamlessly detached from the main application window. This is achieved using an extra layer to the
platform and renderer bindings, which allows Dear ImGui to communicate platform-specific requests such as
"create an additional OS window", "create a render context", "get the OS position of this window" etc.
When using this feature, the coupling with your OS/renderer becomes much tighter than a regular imgui
integration. It is also much more complicated and require more work to integrate correctly.
If you are new to imgui and you are trying to integrate it into your application, first try to ignore
everything related to Viewport and Platform Windows. You'll be able to come back to it later!
Note that if you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit
from improvements and fixes related to viewports and platform windows without extra work on your side.
See 'ImGuiPlatformIO' for details.

Note that Dear ImGui works with Emscripten. The examples_emscripten/ app uses imgui_impl_sdl.cpp and
imgui_impl_opengl3.cpp, but other combinations are possible.
Third-party framework, graphics API and languages bindings are listed at:
https://github.com/ocornut/imgui/wiki/Bindings
Including backends for:
AGS/Adventure Game Studio, Amethyst, bsf, Cinder, Cocos2d-x, Diligent Engine, Flexium,
GML/Game Maker Studio2, GTK3+OpenGL3, Irrlicht Engine, LÖVE+LUA, Magnum, NanoRT, Nim Game Lib,
Ogre, openFrameworks, OSG/OpenSceneGraph, Orx, px_render, Qt/QtDirect3D, SFML, Sokol,
Unreal Engine 4, vtk, Win32 GDI, etc.
Not sure which to use?
Recommended platform/frameworks:
GLFW https://github.com/glfw/glfw Use imgui_impl_glfw.cpp
SDL2 https://www.libsdl.org Use imgui_impl_sdl.cpp
Sokol https://github.com/floooh/sokol Use util/sokol_imgui.h in Sokol repository.
Those will allow you to create portable applications and will solve and abstract away many issues.
---------------------------------------
EXAMPLE APPLICATIONS
---------------------------------------
Building:
Unfortunately in 2020 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 we choose to provide:
- Makefiles for Linux/OSX
- Batch files for Visual Studio 2008+
- A .sln project file for Visual Studio 2012+
- Xcode project files for the Apple examples
Please let us 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.
If you are interested in using Cmake to build and links examples, see:
https://github.com/ocornut/imgui/pull/1713 and https://github.com/ocornut/imgui/pull/3027
example_allegro5/
Allegro 5 example.
= main.cpp + imgui_impl_allegro5.cpp
example_apple_metal/
OSX & iOS + Metal.
= main.m + imgui_impl_osx.mm + imgui_impl_metal.mm
It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
(NB: imgui_impl_osx.mm is currently not as feature complete as other platforms back-ends.
You may prefer to use the GLFW Or SDL back-ends, which will also support Windows and Linux.)
example_apple_opengl2/
OSX + OpenGL2.
= main.mm + imgui_impl_osx.mm + imgui_impl_opengl2.cpp
(NB: imgui_impl_osx.mm is currently not as feature complete as other platforms back-ends.
You may prefer to use the GLFW Or SDL back-ends, which will also support Windows and Linux.)
example_empscripten:
Emcripten + SDL2 + OpenGL3+/ES2/ES3 example.
= main.cpp + imgui_impl_sdl.cpp + imgui_impl_opengl3.cpp
Note that other examples based on SDL or GLFW + OpenGL could easily be modified to work with Emscripten.
We provide this to make the Emscripten differences obvious, and have them not pollute all other examples.
example_glfw_metal/
GLFW (Mac) + Metal example.
= main.mm + imgui_impl_glfw.cpp + imgui_impl_metal.mm
example_glfw_opengl2/
GLFW + OpenGL2 example (legacy, fixed pipeline).
= main.cpp + imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp
**DO NOT USE OPENGL2 CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
**Prefer using OPENGL3 code (with gl3w/glew/glad/glad2/glbinding, you can replace the OpenGL function loader)**
This code is mostly provided as a reference to learn about Dear ImGui integration, because it is shorter.
If your code is using GL3+ context or any semi modern OpenGL calls, using this renderer is likely to
make things more complicated, will require your code to reset many OpenGL attributes to their initial
state, and might confuse your GPU driver. One star, not recommended.
example_glfw_opengl3/
GLFW (Win32, Mac, Linux) + OpenGL3+/ES2/ES3 example (programmable pipeline).
= main.cpp + imgui_impl_glfw.cpp + imgui_impl_opengl3.cpp
This uses more modern OpenGL calls and custom shaders.
Prefer using that if you are using modern OpenGL in your application (anything with shaders).
(Please be mindful that accessing OpenGL3+ functions requires a function loader, which are a frequent
source for confusion for new users. We use a loader in imgui_impl_opengl3.cpp which may be different
from the one your app normally use. Read imgui_impl_opengl3.h for details and how to change it.)
example_glfw_vulkan/
GLFW (Win32, Mac, Linux) + Vulkan example.
= main.cpp + imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp
This is quite long and tedious, because: Vulkan.
For this example, the main.cpp file exceptionally use helpers function from imgui_impl_vulkan.h/cpp.
example_glut_opengl2/
GLUT (e.g., FreeGLUT on Linux/Windows, GLUT framework on OSX) + OpenGL2.
= main.cpp + imgui_impl_glut.cpp + imgui_impl_opengl2.cpp
Note that GLUT/FreeGLUT is largely obsolete software, prefer using GLFW or SDL.
example_marmalade/
Marmalade example using IwGx.
= main.cpp + imgui_impl_marmalade.cpp
example_null
Null example, compile and link imgui, create context, run headless with no inputs and no graphics output.
= main.cpp
This is used to quickly test compilation of core imgui files in as many setups as possible.
Because this application doesn't create a window nor a graphic context, there's no graphics output.
example_sdl_directx11/
SDL2 + DirectX11 example, Windows only.
= main.cpp + imgui_impl_sdl.cpp + imgui_impl_dx11.cpp
This to demonstrate usage of DirectX with SDL.
example_sdl_metal/
SDL2 (Mac) + Metal example.
= main.mm + imgui_impl_sdl.cpp + imgui_impl_metal.mm
example_sdl_opengl2/
SDL2 (Win32, Mac, Linux etc.) + OpenGL example (legacy, fixed pipeline).
= main.cpp + imgui_impl_sdl.cpp + imgui_impl_opengl2.cpp
**DO NOT USE OPENGL2 CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
**Prefer using OPENGL3 code (with gl3w/glew/glad/glad2/glbinding, you can replace the OpenGL function loader)**

example_sdl_opengl3/
SDL2 (Win32, Mac, Linux, etc.) + OpenGL3+/ES2/ES3 example.
= main.cpp + imgui_impl_sdl.cpp + imgui_impl_opengl3.cpp
This uses more modern OpenGL calls and custom shaders.
Prefer using that if you are using modern OpenGL in your application (anything with shaders).
(Please be mindful that accessing OpenGL3+ functions requires a function loader, which are a frequent
source for confusion for new users. We use a loader in imgui_impl_opengl3.cpp which may be different
from the one your app normally use. Read imgui_impl_opengl3.h for details and how to change it.)
example_sdl_vulkan/
SDL2 (Win32, Mac, Linux, etc.) + Vulkan example.
= main.cpp + imgui_impl_sdl.cpp + imgui_impl_vulkan.cpp
This is quite long and tedious, because: Vulkan.
For this example, the main.cpp file exceptionally use helpers function from imgui_impl_vulkan.h/cpp.
example_win32_directx9/
DirectX9 example, Windows only.
= main.cpp + imgui_impl_win32.cpp + imgui_impl_dx9.cpp
example_win32_directx10/
DirectX10 example, Windows only.
= main.cpp + imgui_impl_win32.cpp + imgui_impl_dx10.cpp
example_win32_directx11/
DirectX11 example, Windows only.
= main.cpp + imgui_impl_win32.cpp + imgui_impl_dx11.cpp
example_win32_directx12/
DirectX12 example, Windows only.
= main.cpp + imgui_impl_win32.cpp + imgui_impl_dx12.cpp
This is quite long and tedious, because: DirectX12.

@ -5,14 +5,14 @@ Dear ImGui outputs 16-bit vertex indices by default.
Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile dear imgui with 32-bit indices.
You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
We are providing `imconfig_allegro5.h` that enables 32-bit indices.
Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.

// dear imgui: Renderer + Platform Binding for Allegro 5
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
// Implemented features:
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Platform: Clipboard support (from Allegro 5.1.12)
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// Issues:
// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
// [ ] Platform: Missing gamepad support.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
// https://github.com/ocornut/imgui, Original Allegro 5 code by @birthggd
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2018-11-30: Platform: Added touchscreen support.
// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_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.

// dear imgui: Renderer + Platform Binding for Allegro 5
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
// Implemented features:
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Platform: Clipboard support (from Allegro 5.1.12)
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// Issues:
// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
// [ ] Platform: Missing gamepad support.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.

// dear imgui: Renderer for DirectX10
// This needs to be used along with a Platform Binding (e.g. Win32)
// Implemented features:
// [X] Renderer: User texture binding. Use 'ID3D10ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the 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)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
// 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.
// 2018-02-16: 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.
// 2016-05-07: DirectX10: Disabling depth-write.

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
// 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.
// 2016-05-07: DirectX11: Disabling depth-write.

// dear imgui: Renderer for DirectX12
// This needs to be used along with a Platform Binding (e.g. Win32)

// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// FIXME: The transition from removing a viewport and moving the window in an existing hosted viewport tends to flicker.
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
// Important: to compile on 32-bit systems, this back-end requires code to be compiled with '#define ImTextureID ImU64'.
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
// This define is done in the example .vcxproj file and need to be replicated in your app (by e.g. editing imconfig.h)
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2019-03-29: Misc: Various minor tidying up.
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
// 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.

// dear imgui: Platform Binding for GLFW
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ for full feature support.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Issues:
// [ ] Platform: Multi-viewport support: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the 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)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
// 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, passed to glfwSetCursor()).
// 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 by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
// 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).
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// dear imgui: Platform Binding for GLFW
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan..)
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: 3 cursors types are missing from GLFW.
// [X] Platform: Keyboard arrays indexed using GLFW_KEY_* codes, e.g. ImGui::IsKeyPressed(GLFW_KEY_SPACE).

// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
// - Desktop GL: 2.x 3.x 4.x
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
// Implemented features:
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
// https://github.com/ocornut/imgui
// About Desktop OpenGL function loaders:
// Modern Desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
// Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
// You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
// About GLSL version:
// The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

// dear imgui: Platform Binding for OSX / Cocoa
// This needs to be used along with a Renderer (e.g. OpenGL2, OpenGL3, Vulkan, Metal..)
// [ALPHA] Early bindings, not well tested. If you want a portable application, prefer using the GLFW or SDL platform bindings on Mac.
// Implemented features:
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: OSX clipboard is supported within core Dear ImGui (no specific code in this back-end).
// Issues:
// [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..
// [ ] Platform: Multi-viewport / platform windows.
