Emitted whenever a sequence is cancelled.
This usually happens on active touches when [method@Gtk.EventController.reset] is called on gesture
(manually, due to
grabs...), or the individual sequence
was claimed by parent widgets' controllers (see [method@Gtk.Gesture.set_sequence_state]
).
gesture
must forget everything about sequence
as in response to this signal.
