The "event" signal is emitted
when any GdkEvent is captured by the connected
widget's underlying GdkWindow.
All event signals return false until the event has
been propagated to the widget that will handle it, at which point they
return true, the event is no longer propagated and
the signal is no longer fired.
Each event causes two signal emissions; the generic event signal
described here, and the specific event signal that is being called,
such as the "key-press-event"
signal. The "event" signal
itself is unlikely to be used directly on its own account very often.
All event signals carry the event that caused the signal to be fired as
the first parameter after the connecting widget. You may add as many
parameters as you like that contain data specific to your application.
You can limit or extend the events that are captured by a windowed widget
by setting one or more GdkEventMask flags for the
widget. See add_events() , and
set_events() .
