Detailed Description
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.

Member Function Documentation
QGraphicsPathItem::QGraphicsPathItem(QGraphicsItem *parent = Q_NULLPTR)
Constructs a QGraphicsPath. parent is passed to QAbstractGraphicsShapeItem's constructor.
See also QGraphicsScene::addItem().
QGraphicsPathItem::QGraphicsPathItem(const QPainterPath &path, QGraphicsItem *parent = Q_NULLPTR)
Constructs a QGraphicsPath item using path as the default path. parent is passed to QAbstractGraphicsShapeItem's constructor.
See also QGraphicsScene::addItem().
QGraphicsPathItem::~QGraphicsPathItem()
Destroys the QGraphicsPathItem.
[virtual] QRectF QGraphicsPathItem::boundingRect() const
Reimplemented from QGraphicsItem::boundingRect().
[virtual] bool QGraphicsPathItem::contains(const QPointF &point) const
Reimplemented from QGraphicsItem::contains().
[virtual] bool QGraphicsPathItem::isObscuredBy(const QGraphicsItem *item) const
Reimplemented from QGraphicsItem::isObscuredBy().
[virtual] QPainterPath QGraphicsPathItem::opaqueArea() const
Reimplemented from QGraphicsItem::opaqueArea().
[virtual] void QGraphicsPathItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = Q_NULLPTR)
