pub unsafe fn gesture_cancel_policy(&self) -> GestureCancelPolicy

This property holds the policy for deciding what happens on accepting a gesture

Calls C++ function: QGesture::GestureCancelPolicy QGesture::gestureCancelPolicy() const.

C++ documentation:

This property holds the policy for deciding what happens on accepting a gesture

On accepting one gesture Qt can automatically cancel other gestures that belong to other targets. The policy is normally set to not cancel any other gestures and can be set to cancel all active gestures in the context. For example for all child widgets.

Access functions:

GestureCancelPolicy	gestureCancelPolicy() const
void	setGestureCancelPolicy(GestureCancelPolicy policy)

This property holds the point that is used to find the receiver for the gesture event.

Calls C++ function: QPointF QGesture::hotSpot() const.

C++ documentation:

This property holds the point that is used to find the receiver for the gesture event.

The hot-spot is a point in the global coordinate system, use QWidget::mapFromGlobal() or QGestureEvent::mapToGraphicsScene() to get a local hot-spot.

The hot-spot should be set by the gesture recognizer to allow gesture event delivery to a QGraphicsObject.
