QAbstractGraphicsShapeItem ¶

概要 ¶

详细描述 ¶

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.
