GtkGesture::cancel

void
cancel (
  GtkGesture* self,
  GdkEventSequence* sequence,
  gpointer user_data
)

Emitted whenever a sequence is cancelled.

This usually happens on active touches when gtk_event_controller_reset() is called on gesture (manually, due to grabs…), or the individual sequence was claimed by parent widgets’ controllers (see gtk_gesture_set_sequence_state()).

gesture must forget everything about sequence as in response to this signal.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

`sequence`	`GdkEventSequence`
	The `GdkEventSequence` that was cancelled.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
