Public Member Functions inherited from QSinglePointEvent
Qt::MouseButton button () const
 Returns the button that caused the event.
Qt::MouseButtons buttons () const
 Returns the button state when the event was generated.
QPointF position () const
 Returns the position of the point in this event, relative to the widget or item that received the event.
QPointF scenePosition () const
 Returns the position of the point in this event, relative to the window or scene.
QPointF globalPosition () const
 Returns the position of the point in this event on the screen or virtual desktop.
bool isBeginEvent () const override
 Returns true if this event represents a \l {button()}{button} being pressed.
bool isUpdateEvent () const override
 Returns true if this event does not include a change in \l {buttons()}{button state}.
bool isEndEvent () const override
 Returns true if this event represents a \l {button()}{button} being released.

const QPointingDevice * pointingDevice () const
 Returns the source device from which this event originates.

 Returns a QEventPoint reference for the point at index i.
const QList< QEventPoint > & points () const
 Returns a list of points in this pointer event.
QEventPoint * pointById (int id)
 Returns the point whose \l {QEventPoint::id()}{id} matches the given id, or nullptr if no such point is found.
bool allPointsGrabbed () const
 Returns true if every point in points() has either an exclusiveGrabber() or one or more passiveGrabbers().
bool allPointsAccepted () const
 Returns true if isPointAccepted() is true for every point in points(); otherwise false.
virtual void setAccepted (bool accepted) override
 \reimp
QObject * 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.
void 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.
QList< QPointer< QObject > > 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.
void clearPassiveGrabbers (const QEventPoint &point)
 Removes all passive grabbers from the given point.
bool 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.
bool removePassiveGrabber (const QEventPoint &point, QObject *grabber)
 Removes the passive grabber from the given point if it was previously added.
Public Member Functions inherited from QInputEvent
 QInputEvent (Type type, const QInputDevice *m_dev, Qt::KeyboardModifiers modifiers=Qt::NoModifier)
const QInputDevice * device () const
QInputDevice::DeviceType deviceType () const
 Returns the type of device that generated the event.
Qt::KeyboardModifiers modifiers () const
 Returns the keyboard modifier flags that existed immediately before the event occurred.
void setModifiers (Qt::KeyboardModifiers modifiers)
quint64 timestamp () const
 Returns the window system's timestamp for this event.
Public Member Functions inherited from QEvent
 QEvent (Type type)
 Constructs an event object of type type.
virtual ~QEvent ()
 Destroys the event.
Type type () const
 Returns the event type.
bool spontaneous () const
 Returns true if the event originated outside the application (a system event); otherwise returns false.
bool isAccepted () const
void accept ()
 Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
void ignore ()
 Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
bool isInputEvent () const noexcept
bool isPointerEvent () const noexcept
bool isSinglePointEvent () const noexcept
virtual QEvent * clone () const
 Creates and returns an identical copy of this event.
