Gtk.Widget::key-press-event

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

The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.

To receive this signal, the Gdk.Window associated to the widget needs to enable the #GDK_KEY_PRESS_MASK mask.

This signal will be sent to the grab widget if there is one.

widget: instance of Gtk.Widget that is emitting the signal
event: the Gdk.EventKey which triggered this signal.
Returns: true to stop other handlers from being invoked for the event. false to propagate the event further.
