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.

A graphics path item |
Constructs a QGraphicsPath. parent is passed to QAbstractGraphicsShapeItem's constructor.
See also QGraphicsScene::addItem().
Constructs a QGraphicsPath item using path as the default path. parent is passed to QAbstractGraphicsShapeItem's constructor.
See also QGraphicsScene::addItem().
