Thanks for your reply.

It works for the horizontalHeader() as well.

The final solution to my problem looks a little different, I am now 
calling a custom function, because I would like to check some things 
before displaying the context menu:

         self.setContextMenuPolicy(Qt.CustomContextMenu)
         self.connect(self, SIGNAL("customContextMenuRequested(const 
QPoint &)"), self.on_context_menu_table)

         hdr = self.horizontalHeader()
         hdr.setContextMenuPolicy(Qt.CustomContextMenu)
         hdr.connect(hdr, SIGNAL("customContextMenuRequested(const 
QPoint &)"), self.on_context_menu_header)


In the handler, I am using something like this

         self.datasetMenu.exec_(self.cursor().pos())
