Expand description

Trait containing all EventController methods.

Implementors

EventControllerKey, EventControllerMotion, EventControllerScroll, EventController, Gesture, PadController

Required methods

Gets the propagation phase at which self handles events.

Returns

the propagation phase

Returns the Widget this controller relates to.

Returns

a Widget

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

event

a GdkEvent

Returns

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().

phase
