| // ImGui SDL2 binding with OpenGL3 |
| // (SDL 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. |
| // Missing features: |
| // [ ] SDL2 handling of IME under Windows appears to be broken and it explicitly disable the regular Windows IME. You can restore Windows IME by compiling SDL with SDL_DISABLE_WINDOWS_IME. |
| |
| // 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. |
