contextMenuEvent clashing

PyQt4

I am sub classing QGraphicsView & QGraphicsItem.

I do have a contextMenuEvent in both of them. How ever while right clicking on item creates the menu of view. It's not creating the menu defined in item.

If I disable the menu of view, item's menu is working fine.

How do I ignore this clashing?

Here is code of Item's contextMenuEvent

Code:

---

def contextMenuEvent(self, event):
        menu = QtGui.QMenu()
        menu.addAction("Copy")
        menu.addAction("Paste")
        menu.exec_(event.screenPos())

---

Code of view's contextMenuEvent

Code:

---

menu = .....
.....
menu.exec_(event.globalPos())

---

Call the base class implementation of the method in the view.
