title: mouse hover on drawn shapes of a qgraphicsitem pyqt4
body: <p>I have a QGraphicsItem with drawn shapes (below image). How do I detect if the mouse pointer is over the circle, the text or the green rect? All shapes were drawn using the painter method (i.e.: painter.drawText()).</p>

  <p>Would be possible make this using a QGraphicsItem into its parent (also a QGraphicsItem) and use the hover mouse events?</p>
