Well there is QtGui.QCursor.pos()

So you can exec_ the menu using that.

You can use the indexAt function that is part of the treeview class and 
give it the cursor position to get the index.

I would connect to signal customContextMenuRequested instead of what 
your doing though.

Something like:

self.treeView.setContextMenuPolicy(QtCore.Qt.CustomConextMenu)
self.connect(self.treeview, 
QtCore.SIGNAL("customContextMenuRequested(const QPoint &)"), self.doMenu)


def doMenu(self, point)
         treeidx=self.treeview.indexAt(point)
	popupmenu.exec_(point)


Hope this is helpful.
