egui::containers::panel

Struct CentralPanel

source
pub struct CentralPanel { /* private fields */ }
Expand description

A panel that covers the remainder of the screen, i.e. whatever area is left after adding other panels.

The order in which you add panels matter! The first panel you add will always be the outermost, and the last you add will always be the innermost.

CentralPanel must be added after all other panels!

NOTE: Any crate::Windows and crate::Areas will cover the top-level CentralPanel.

See the module level docs for more details.

egui::TopBottomPanel::top("my_panel").show(ctx, |ui| {
   ui.label("Hello World! From `TopBottomPanel`, that must be before `CentralPanel`!");
});
egui::CentralPanel::default().show(ctx, |ui| {
   ui.label("Hello World!");
});
