Detailed Description
QGraphicsEllipseItem respresents an ellipse with a fill and an outline, and you can also use it for ellipse segments (see startAngle(), spanAngle()).
 |  |
To set the item's ellipse, pass a QRectF to QGraphicsEllipseItem's constructor, or call setRect(). The rect() function returns the current ellipse geometry.
QGraphicsEllipseItem uses the rect and the pen width to provide a reasonable implementation of boundingRect(), shape(), and contains(). The paint() function draws the ellipse using the item's associated pen and brush, which you can set by calling setPen() and setBrush().
