Gesture.connectCancel

Connect to Cancel signal.

This signal is emitted whenever a sequence is cancelled. This usually happens on active touches when gtk.event_controller.EventController.reset is called on gesture (manually, due to grabs...), or the individual sequence was claimed by parent widgets' controllers (see gtk.gesture.Gesture.setSequenceState).

gesture must forget everything about sequence as a reaction to this signal.
