## Detailed Description

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.

## Member Function Documentation

### QGraphicsSceneMoveEvent::QGraphicsSceneMoveEvent()

Constructs a QGraphicsSceneMoveEvent.

### `[virtual]` 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).
