public class QGraphicsPolygonItem
extends QAbstractGraphicsShapeItem

The QGraphicsPolygonItem class provides a polygon item that you can add to a QGraphicsScene. To set the item's polygon, pass a QPolygonF to QGraphicsPolygonItem's constructor, or call the setPolygon() function. The polygon() function returns the current polygon.

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