pub trait HandleEvent<Event, KeyMap, R: ConsumedEvent> {
    // Required method
    fn handle(&mut self, event: &Event, keymap: KeyMap) -> R;
}
Expand description

A very broad trait for an event handler for widgets.

As widget types are only short-lived, this trait should be implemented for the state type. Thereby it can modify any state, and it can return an arbitrary result, that fits the widget.

Required Methods§
