Module glutin::event

The Event enum and assorted supporting types.

These are sent to the closure given to EventLoop::run(...), 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(...) like this:

let mut control_flow = ControlFlow::Poll;
let mut start_cause = StartCause::Init;

while control_flow != ControlFlow::Exit {
    event_handler(NewEvents(start_cause), ..., &mut control_flow);

    for e in (window events, user events, device events) {
        event_handler(e, ..., &mut control_flow);
    }
    event_handler(MainEventsCleared, ..., &mut control_flow);

    for w in (redraw windows) {
        event_handler(RedrawRequested(w), ..., &mut control_flow);
    }
    event_handler(RedrawEventsCleared, ..., &mut control_flow);

    start_cause = wait_if_necessary(control_flow);
}

event_handler(LoopDestroyed, ..., &mut control_flow);

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