@ -2,15 +2,17 @@ Those are standalone ready-to-build applications to demonstrate ImGui.

Binaries of some of those demos are available at http://www.miracleworld.net/imgui/binaries

TL;DR;
|
|
|
|
|
Newcomers, read 'Programmer guide' imgui.cpp for notes on how to setup ImGui in your codebase.
|
|
|
|
|
Refer to 'opengl_example' to understand how the library is setup, because it is the simplest one.
|
|
|
|
|
Copy the imgui_impl_xxx.cpp/.h files you need if you are using one of provided rendering/IO backends.
|
|
|
|
|
If using different or your own backend, copy opengl_example/imgui_impl_opengl.cpp/.h to get started.

The other examples requires more boilerplate and are harder to read.
|

|
|
|
- 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.
|
|
|
|
|
- If you have your own engine, you probably want to start from 'opengl_example' and adapt it to
|
|
|
|
|
your engine, but you can read the other examples as well.

ImGui is highly portable and only requires a few things to run:
|
|
|
|
|
- Providing mouse/keyboard inputs
|
|
|
|
|
- Load the font atlas texture into GPU memory

- 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.
