Подробное описание
The QAbstractGraphicsShapeItem class provides a common base for all path items.
This class does not fully implement an item by itself; in particular, it does not implement boundingRect() and paint(), which are inherited by QGraphicsItem.
You can subclass this item to provide a simple base implementation of accessors for the item's pen and brush.
See also QGraphicsRectItem, QGraphicsEllipseItem, QGraphicsPathItem, QGraphicsPolygonItem, QGraphicsTextItem, QGraphicsLineItem, QGraphicsPixmapItem, and The Graphics View Framework.
