All Implemented Interfaces:

public class QGraphicsPathItem
extends QAbstractGraphicsShapeItem

The QGraphicsPathItem class provides a path item that you can add to a QGraphicsScene.

To set the item's path, pass a QPainterPath to QGraphicsPathItem's constructor, or call the setPath function. The path function returns the current path.

QGraphicsPathItem uses the path to provide a reasonable implementation of boundingRect, shape, and contains. The paint function draws the path using the item's associated pen and brush, which you can set by calling the setPen and setBrush functions.
