1 // ImGui GLFW binding with OpenGL (legacy, fixed pipeline)
2 // (GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
3 
4 // Implemented features:
5 //  [X] User texture binding. Cast 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
6 
7 // **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
8 // **Prefer using the code in the opengl3_example/ folder**
9 // See imgui_impl_glfw.cpp for details.
10 
11 // You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
12 // If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
13 // If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
