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. 14 // https://github.com/ocornut/imgui 15 16 struct GLFWwindow; 17 18 IMGUI_API bool ImGui_ImplGlfwGL2_Init(GLFWwindow* window, bool install_callbacks); 19 IMGUI_API void ImGui_ImplGlfwGL2_Shutdown(); 20 IMGUI_API void ImGui_ImplGlfwGL2_NewFrame(); 21 IMGUI_API void ImGui_ImplGlfwGL2_RenderDrawData(ImDrawData* draw_data); 22 23 // Use if you want to reset your rendering device without losing ImGui state. 24 IMGUI_API void ImGui_ImplGlfwGL2_InvalidateDeviceObjects(); 25 IMGUI_API bool ImGui_ImplGlfwGL2_CreateDeviceObjects(); 26 27 // GLFW callbacks (registered by default to GLFW if you enable 'install_callbacks' during initialization) 28 // Provided here if you want to chain callbacks yourself.
