Gtk.Widget::event

function callback(widget, event:Gdk.Event, ):Boolean;

The GTK+ main loop will emit three signals for each GDK event delivered to a widget: one generic ::event signal, another, more specific, signal that matches the type of event delivered (e.g. Gtk.key-press-event) and finally a generic Gtk.event-after signal.

widget: instance of Gtk.Widget that is emitting the signal
event: the Gdk.Event which triggered this signal
Returns: true to stop other handlers from being invoked for the event and to cancel the emission of the second specific ::event signal. false to propagate the event further and to allow the emission of the second signal. The ::event-after signal is emitted regardless of the return value.
