pub unsafe fn set_timeout(msecs: c_int)

Set the timeout, in milliseconds, before the gesture triggers.

Calls C++ function: static void QTapAndHoldGesture::setTimeout(int msecs).

C++ documentation:

Set the timeout, in milliseconds, before the gesture triggers.

The recognizer will detect a touch down and if msecs later the touch is still down, it will trigger the QTapAndHoldGesture. The default value is 700 milliseconds.

See also timeout().

Gets the timeout, in milliseconds, before the gesture triggers.

Calls C++ function: static int QTapAndHoldGesture::timeout().

C++ documentation:

Gets the timeout, in milliseconds, before the gesture triggers.

The recognizer will detect a touch down and if timeout() later the touch is still down, it will trigger the QTapAndHoldGesture. The default value is 700 milliseconds.

See also setTimeout().

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 whether the gesture has a hot-spot

Access functions:

bool	hasHotSpot() const

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.
