Detailed Description#

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.
