How to always repaint

[dejang]

I am developing a music player with egui and while playing a song the UI only updates while I move the mouse or do some kind of interaction. I'd like it to always update. Is that possible with egui ?

Yes, you just have to make sure Context::request_repaint gets called on every frame. There is an example in the demo app:

egui/crates/egui_demo_app/src/backend_panel.rs

Lines 61 to 74 in a0f4faf

	pub fn update(&mut self, ctx: &egui::Context, frame: &eframe::Frame) {
	self.frame_history
	.on_new_frame(ctx.input(|i| i.time), frame.info().cpu_usage);
	match self.run_mode {
	RunMode::Continuous => {
	// Tell the backend to repaint as soon as possible
	ctx.request_repaint();
	}
	RunMode::Reactive => {
	// let the computer rest for a bit
	}
	}
	}

Ahh thanks, basically calling ctx.request_repaing() in the update method of the App repaints the whole thing. This is what I needed.
