Required Methods

Gets the propagation phase at which self handles events.


the propagation phase

Returns the Widget this controller relates to.


a Widget

Feeds an events into self, so it can be interpreted and the controller actions triggered.


a GdkEvent


true if the event was potentially useful to trigger the controller action

Resets the self to a clean state. Every interaction the controller did through signal::EventController::handle-event will be dropped at this point.

Sets the propagation phase at which a controller handles events.

If phase is PropagationPhase::None, no automatic event handling will be performed, but other additional gesture maintenance will. In that phase, the events can be managed by calling handle_event().
