Detailed Description
The QGraphicsSceneMoveEvent class provides events for widget moving in the graphics view framework.
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.
See also QGraphicsItem::setPos(), QGraphicsItem::ItemPositionChange, and QGraphicsItem::ItemPositionHasChanged.

QGraphicsSceneMoveEvent::QGraphicsSceneMoveEvent()
Constructs a QGraphicsSceneMoveEvent.
QGraphicsSceneMoveEvent::~QGraphicsSceneMoveEvent()
Destroys the QGraphicsSceneMoveEvent.
QPointF QGraphicsSceneMoveEvent::newPos() const
Returns the new position (i.e., the current position).
See also oldPos() and QGraphicsItem::setPos().
QPointF QGraphicsSceneMoveEvent::oldPos() const
Returns the old position (i.e., the position immediately before the widget was moved).
