Dear ImGui: Immediate Mode GUI Library for C++
An open source library for creating fast and easy-to-use graphical user interfaces in games or applications, written in C++.
What is Dear ImGui?
Dear ImGui is an immediate mode graphical user interface library for C++. It is designed to be easy to use and integrate into games or applications to create fast graphical user interfaces requiring minimal code. Some key features of Dear ImGui include:
- Minimal dependencies - Uses only a single header file and requires OpenGL or DirectX for rendering
- Immediate mode - UIs are built command-by-command instead of using pre-compiled resources, allowing for flexibility and interactivity
- Portable - Supports a variety of platforms including Windows, Linux, macOS
- Extensible and customizable - Can be extended through code and themes/skins
- Good documentation and examples - Well documented APIs and gallery showcasing capabilities and code snippets
Dear ImGui is commonly used by game developers to quickly create debug UIs, tools UIs, or in-game UIs such as settings menus and HUDs. It emphasizes simplicity and performance over fancy GUI features, making it fast and easy to integrate. The immediate mode approach allows creating UIs that can change dynamically at runtime.
