Widget Events
From Documentation
A widget event is the widget-level event (Event). Like Event at the server side, the widget event is usually triggered to a widget (and an application) to notify a widget-level event, such as a window has been moved.
A widget event will be propagated to the parent widget, parent's parent and so on, until stopped (Event.stop(Map)). Then, if the event is required by the server, it will be sent to the server, and converted to an instance of AuRequest at the server[1].
To fire a widget event, you could invoke Widget.fire(String, Object, Map, int) or Widget.fireX(Event, int).
To listen a widget event, you could invoke Widget.listen(Map, int).
