src/imgui/imgui_demo.cpp
// dear imgui, v1.90.2 WIP
// dear imgui, v1.91.5
// (demo code)
// Help:
......
// - Need help integrating Dear ImGui in your codebase?
// - Read Getting Started https://github.com/ocornut/imgui/wiki/Getting-Started
// - Read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
// Read imgui.cpp for more details, documentation and comments.
// Read top of imgui.cpp and imgui.h for many details, documentation, comments, links.
// Get the latest version at https://github.com/ocornut/imgui
// How to easily locate code?
// - Use Tools->Item Picker to debug break in code by clicking any widgets: https://github.com/ocornut/imgui/wiki/Debug-Tools
// - Browse an online version the demo with code linked to hovered widgets: https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html
// - Find a visible string and search for it in the code!
//---------------------------------------------------
// PLEASE DO NOT REMOVE THIS FILE FROM YOUR PROJECT!
//---------------------------------------------------
......
// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.
// Navigating this file:
// - In Visual Studio: CTRL+comma ("Edit.GoToAll") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments.
// - In Visual Studio: CTRL+comma ("Edit.GoToAll") can follow symbols inside comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
// - In Visual Studio w/ Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols inside comments.
// - In VS Code, CLion, etc.: CTRL+click can follow symbols inside comments.
// - You can search/grep for all sections listed in the index to find the section.
