egui
(pronounced “e-gooey”) is a simple, fast, and portable immediate mode GUI library written in Rust. It is designed to provide an easy-to-use interface for creating graphical user interfaces (GUIs) in Rust applications.
Whether you are building a web app, a desktop application, or integrating a GUI into a game engine, egui
offers a versatile solution. Below, we explore its tools and functionality.
egui
egui
operates on the immediate mode paradigm, which means the GUI is redrawn every frame. This approach eliminates the need for callbacks or retained states, simplifying the code structure. For example: if ui.button("Click me!").clicked() {
println!("Button clicked!");
}
egui
is highly portable and works seamlessly across platforms such as Web (via WebAssembly), Linux, macOS, Windows, and Android. The official framework, eframe
, facilitates this compatibility.egui
provides a variety of widgets like buttons, sliders, checkboxes, text fields, color pickers, and more. It also supports flexible layouts—horizontal, vertical, columns, and automatic wrapping.egui
can be integrated into existing game engines or platforms due to its modular design. It only requires textured triangle rendering to function.egui
ensures safety while maintaining performance.egui
While egui
is easy to use and versatile, it does have some drawbacks:
egui
is an excellent choice for Rust developers seeking a straightforward way to build GUIs for interactive applications or games.
With its focus on simplicity, portability, and customization, it empowers developers to create responsive interfaces efficiently while maintaining code clarity.
