## Detailed Description

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.

### QAbstractGraphicsShapeItem::~QAbstractGraphicsShapeItem ()

Destroys a QAbstractGraphicsShapeItem.

### QBrush QAbstractGraphicsShapeItem::brush () const

Returns the item's brush, or an empty brush if no brush has been set.

See also setBrush().

### QPen QAbstractGraphicsShapeItem::pen () const

Returns the item's pen. If no pen has been set, this function returns QPen(), a default black solid line pen with 0 width.
