/**
* GtkGesture::begin:
* @gesture: the object which received the signal
- * @sequence: the #GdkEventSequence that made the gesture to be recognized
+ * @sequence: (nullable): the #GdkEventSequence that made the gesture to be recognized
*
* This signal is emitted when the gesture is recognized. This means the
* number of touch sequences matches #GtkGesture:n-points.
/**
* GtkGesture::end:
* @gesture: the object which received the signal
- * @sequence: the #GdkEventSequence that made gesture recognition to finish
+ * @sequence: (nullable): the #GdkEventSequence that made gesture recognition to finish
*
* This signal is emitted when @gesture either stopped recognizing the event
* sequences as something to be handled, or the number of touch sequences became
/**
* GtkGesture::update:
* @gesture: the object which received the signal
- * @sequence: the #GdkEventSequence that was updated
+ * @sequence: (nullable): the #GdkEventSequence that was updated
*
* This signal is emitted whenever an event is handled while the gesture is
* recognized. @sequence is guaranteed to pertain to the set of active touches.
/**
* GtkGesture::cancel:
* @gesture: the object which received the signal
- * @sequence: the #GdkEventSequence that was cancelled
+ * @sequence: (nullable): the #GdkEventSequence that was cancelled
*
* This signal is emitted whenever a sequence is cancelled. This usually
* happens on active touches when gtk_event_controller_reset() is called
/**
* GtkGesture::sequence-state-changed:
* @gesture: the object which received the signal
- * @sequence: the #GdkEventSequence that was cancelled
+ * @sequence: (nullable): the #GdkEventSequence that was cancelled
* @state: the new sequence state
*
* This signal is emitted whenever a sequence state changes. See
