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.
