// ImGui GLFW binding with OpenGL3 + shaders
|
|
// (GLFW 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.
|
|
// [X] Gamepad navigation mapping. Enable with 'io.NavFlags |= ImGuiNavFlags_EnableGamepad'.
|
|
|
|
// 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.
