This document holds the user-facing changelog that we also use in release notes.
We generally fold multiple commits pertaining to the same topic as a single entry.
Changes to the examples/bindings are included within the individual .cpp files in the examples/ folder.
Changes to backends are also included within the individual .cpp files of each backend.

If this happens using the standard back-ends it is probably that the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).

We carry the information to identify a "texture" in the ImTextureID type.
ImTextureID is nothing more that a void*, aka 4/8 bytes worth of data: just enough to store 1 pointer or 1 integer of your choice.
Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely pass ImTextureID values until they reach your rendering function.

- If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better knowing how your codebase is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them.

### Q: How can I interact with standard C++ types (such as std::string and std::vector)?
- Being highly portable (bindings for several languages, frameworks, programming style, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engines, dear imgui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases.

- To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h).
- To use combo boxes and list boxes with `std::vector` or any other data structure: the `BeginCombo()/EndCombo()` API
lets you iterate and submit items yourself, so does the `ListBoxHeader()/ListBoxFooter()` API.

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 auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. It is designed for creating binding to other languages. If possible, 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 [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for various third-party bindings.

### Integration
On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/examples) files without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more of the imgui_impl_xxxx files instead of rewriting them: this will be less work for you and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom binding using your custom engine functions if you wish so.

You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so.
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 at ease with those concepts, it should take you less than two hours to integrate Dear ImGui in your custom engine. **Make sure to spend time reading the [FAQ](https://www.dearimgui.org/faq), comments, and some of the examples/ application!**

seamlessly detached from the main application window. This is achieved using an extra layer to the

GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
---------------------------------------------------------------
- Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- In the majority of cases you should be able to use unmodified back-ends files available in the examples/ folder.
- Add the Dear ImGui source files + selected back-end source files to your projects or using your preferred build system.
- In the majority of cases you should be able to use unmodified backends files available in the examples/ folder.
- Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL).
- You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
- When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function 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. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render().
- Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code.
- Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.
- If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.

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.
When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends 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
