Module cosmic::iced_winit::winit::event

Expand description

The event enums and assorted supporting types.

These are sent to the closure given to EventLoop::run_app(...), where they get processed and used to modify the program state. For more details, see the root-level documentation.

Some of these events represent different “parts” of a traditional event-handling loop. You could approximate the basic ordering loop of EventLoop::run_app(...) like this:

let mut start_cause = StartCause::Init;

while !elwt.exiting() {
    app.new_events(event_loop, start_cause);

    for event in (window events, user events, device events) {
        // This will pick the right method on the application based on the event.
        app.handle_event(event_loop, event);
    }

    for window_id in (redraw windows) {
        app.window_event(event_loop, window_id, RedrawRequested);
    }

    app.about_to_wait(event_loop);
    start_cause = wait_if_necessary();
}

app.exiting(event_loop);

This leaves out timing details like ControlFlow::WaitUntil but hopefully describes what happens in what order.
