Public Member Functions
	QGraphicsSceneMoveEvent ()
	Constructs a QGraphicsSceneMoveEvent.
	~QGraphicsSceneMoveEvent ()
	Destroys the QGraphicsSceneMoveEvent.
QPointF	oldPos () const
	Returns the old position (i.e., the position immediately before the widget was moved).
void	setOldPos (const QPointF &pos)
QPointF	newPos () const
	Returns the new position (i.e., the current position).
void	setNewPos (const QPointF &pos)
Public Member Functions inherited from QGraphicsSceneEvent
	QGraphicsSceneEvent (Type type)
	~QGraphicsSceneEvent ()
	Destroys the event.
QWidget *	widget () const
	Returns the widget where the event originated, or \nullptr if the event originates from another application.
void	setWidget (QWidget *widget)
quint64	timestamp () const
void	setTimestamp (quint64 ts)
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.
virtual void	setAccepted (bool accepted)
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.

Detailed Description

The QGraphicsSceneMoveEvent class provides events for widget moving in the graphics view framework.

Since

4.4

\inmodule QtWidgets

A QGraphicsWidget sends itself a QGraphicsSceneMoveEvent immediately when its local position changes. The delivery is implemented as part of QGraphicsItem::itemChange().

It's similar to QMoveEvent, but its positions, oldPos() and newPos(), use QPointF instead of QPoint.
