Detailed Description▲
Member Function Documentation▲
bool QPointerEvent::addPassiveGrabber(const QEventPoint &point, QObject *grabber)▲
Informs the delivery logic that the given grabber is to receive all future update events and the release event containing the given point, regardless where else those events may be delivered.
It's only for use by Qt Quick Input Handlers.
Returns false if grabber was already added, true otherwise.
bool QPointerEvent::allPointsAccepted() const▲
Returns true if isPointAccepted() is true for every point in points(); otherwise false.
bool QPointerEvent::allPointsGrabbed() const▲
Returns true if every point in points() has either an exclusiveGrabber() or one or more passiveGrabbers().
void QPointerEvent::clearPassiveGrabbers(const QEventPoint &point)▲
Removes all passive grabbers from the given point.
It's only for use by Qt Quick Input Handlers.

QObject *QPointerEvent::exclusiveGrabber(const QEventPoint &point) const▲
Returns the object which has been set to receive all future update events and the release event containing the given point.
It's mainly for use in Qt Quick at this time.

QList<QPointer<QObject>> QPointerEvent::passiveGrabbers(const QEventPoint &point) const▲
Returns the list of objects that have been requested to receive all future update events and the release event containing the given point.
It's only for use by Qt Quick Input Handlers.

QEventPoint &QPointerEvent::point(qsizetype i)▲
Returns a QEventPoint reference for the point at index i.
QEventPoint *QPointerEvent::pointById(int id)▲
Returns the point whose id matches the given id, or nullptr if no such point is found.
qsizetype QPointerEvent::pointCount() const▲
Returns the number of points in this pointer event.
QPointingDevice::PointerType QPointerEvent::pointerType() const▲
Returns the type of point that generated the event.
const QPointingDevice *QPointerEvent::pointingDevice() const▲
Returns the source device from which this event originates.
This is the same as QInputEvent::device() but typecast for convenience.
const QList<QEventPoint> &QPointerEvent::points() const▲
Returns a list of points in this pointer event.
bool QPointerEvent::removePassiveGrabber(const QEventPoint &point, QObject *grabber)▲
Removes the passive grabber from the given point if it was previously added. Returns true if it had been a passive grabber before, false if not.
It's only for use by Qt Quick Input Handlers.

[override virtual] void QPointerEvent::setAccepted(bool accepted)▲
Reimplements an access function for property: QEvent::accepted.
void QPointerEvent::setExclusiveGrabber(const QEventPoint &point, QObject *exclusiveGrabber)▲
Informs the delivery logic that the given exclusiveGrabber is to receive all future update events and the release event containing the given point, and that delivery to other items can be skipped.
It's mainly for use in Qt Quick at this time.
