Подробное описание

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.

QGraphicsPathItem::QGraphicsPathItem ( const QPainterPath & path, QGraphicsItem * parent = 0 )

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.

QPainterPath QGraphicsPathItem::path () const

Returns the item's path as a QPainterPath. If no item has been set, an empty QPainterPath is returned.
