Gesture.connectCancel

gulong connectCancel(T)(T callback,  Flag!"After" after =  No.After) if (isCallable!T
    &&  is(ReturnType!T ==  void)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0]  ==  gdk.event_sequence.EventSequence)))
   && (Parameters!T.length <  2 || (ParameterStorageClassTuple!T[1]  ==  ParameterStorageClass.none &&  is(Parameters!T[1] :  gtk.gesture.Gesture)))

Connect to Cancel signal.

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 in response 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 gdk.event_sequence.EventSequence 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
