The path should be in (this) item coordinates, not scene coordinates.
Plus you're bounding rect should include the pen width of the path
you're drawing, eg:
halfPenWidth = self.pen.width()/2.0;
return self.path.boundingRect().adjusted(-halfPenWidth, -halfPenWidth
, halfPenWidth , halfPenWidth )
Hope this helps.
