Dear ImGui Integration Guide

Yapay zekadan makale özeti

Preamble and Setup: Tutorial focuses on integrating Dear ImGui into C++ applications
Examples provided demonstrate various windowing and graphics APIs
Examples are raw and cannot showcase texture usage
Game loop assumes continuous updates at 60 FPS
Compilation and Linking: Dear ImGui can be built as master or docking branch
Include imgui/ and corresponding backend files in project
Direct linking recommended over static/shared library approach
Most linking issues stem from underlying windowing/graphics tech
Backend Integration: Multiple backend combinations supported including DirectX11/12, GLFW, SDL2
Each backend requires specific initialization and event handling
Docking and multi-viewports features available in docking branch
Vulkan integration most complex but works with most setups
Usage: Create Dear ImGui context with ImGui::CreateContext()
Initialize platform and rendering backends
Poll events and call backend functions during main loop
Destroy context and call backend shutdown functions
Check input capture settings in application logic
