Public Member Functions
	QGraphicsSceneMoveEvent ()
	Constructs a QGraphicsSceneMoveEvent.

	~QGraphicsSceneMoveEvent ()
	Destroys the QGraphicsSceneMoveEvent.

	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.

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.

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.
