public class QGraphicsRectItem
The QGraphicsRectItem class provides a rectangle item that you can add to a QGraphicsScene.
To set the item's rectangle, pass a QRectF to QGraphicsRectItem's constructor, or call the setRect function. The rect function returns the current rectangle.

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