    &&  is(ReturnType!T ==  void)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0]  ==  gdk.event_sequence.EventSequence)))

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.

Parameters

`callback`	signal callback delegate or function to connect `void callback(gdk.event_sequence.EventSequence sequence, gtk.gesture.Gesture gesture)` `sequence` the #GdkEventSequence that was cancelled (optional) `gesture` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
