// ImGui SDL2 binding with OpenGL (legacy, fixed pipeline)
|
|
// (SDL 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 sdl_opengl3_example/ folder**
|
|
// See imgui_impl_sdl.cpp for details.
|
|
|
|
// 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.
