Crate egui_sdl2 

egui-sdl2

Integration between egui and sdl2.

Features

• Translate SDL2 events into egui events.
• Handle egui::PlatformOutput (clipboard, cursor updates, links).
• Render with the SDL2 software renderer via sdl2::render::Canvas (canvas-backend feature).
• Render with OpenGL via glow (glow-backend feature).
• Render with WebGPU via wgpu (wgpu-backend feature).
• Or let EguiWindow pick: it walks a list of renderers and keeps the first the device actually supports.

Usage

// Create SDL2 window and canvas:
let sdl = sdl2::init().unwrap();
let video = sdl.video().unwrap();
let window = video.window("Egui SDL2 Canvas", 800, 600).build().unwrap();
let mut canvas = window.into_canvas().build().unwrap();
// Create egui renderer; the canvas stays yours:
let mut egui = egui_sdl2::EguiCanvas::new(&canvas);
let mut event_pump = sdl.event_pump().unwrap();
loop {
   // Feed SDL2 events into egui:
   for event in event_pump.poll_iter() {
       egui.on_event(&canvas, &event);
   }
   // Call `run` + `paint` each frame, over anything you drew yourself:
   egui.run(|ctx: &egui::Context| {});
   canvas.clear();
   egui.paint(&mut canvas);
   canvas.present();
   std::thread::sleep(std::time::Duration::from_secs_f64(1.0 / 60.0));
}

Modules

canvas

Integration between egui and SDL2’s sdl2::render::Canvas API.

glow

Integration between egui and glow for SDL2 applications.

rotation

Presenting the UI at a quarter turn to the window, for a panel that is not mounted the way it is read: egui lays out for the turned screen, and the backend puts that frame on the window the other way round.

state

State management for egui + SDL2 integration.

wgpu

Integration between egui and wgpu API.

window

A window plus the best renderer it can get: EguiWindow walks a list of Renderers and keeps the first that comes up, so an app on a device with missing or broken GL drivers still shows a UI instead of exiting.

Structs

EguiRunOutput

The results of running one frame of egui.
