Diagram Scene Example - two overlapping ellipses

[dougluna]

Hello forum,

I believe almost everyone in the forum have gone through the diagramscene example that comes along with in the Qt Demo.

I have included a new shape - ellipse in the editor, using this at DiagramItem:

elif self.diagramType == self.Ellipse:
     item =  QtGui.QGraphicsEllipseItem(-80,-80,160,160)
     self.myPolygon = item.shape().toFillPolygon()

elif self.diagramType == self.Ellipse:
     item =  QtGui.QGraphicsEllipseItem(-80,-80,160,160)
     self.myPolygon = item.shape().toFillPolygon()

To copy to clipboard, switch view to plain text mode 

Now, i want to have a new shape with two overlapping ellipses, like the figure below:

I tried to use Arc, setStartAngle and setSpanAngle, but i was not successful.

Any hint about it?

Thanks!
