[pygtk] How do I add Scrollbar in a TreeViewModel?

[Markus W. Barth]

A (more or less) real world example

<snippet>
 phone_model = models.SlaveListModel('phones', model.Phone)
        controller.add_slave_model(phone_model)
        self.phone_list.set_model(phone_model)
        
        self.phone_list.set_foreign_key(3, model.LineType,'lineTypeID','name')
        
        scrolled_window = gtk.ScrolledWindow()
        scrolled_window.add_with_viewport(self.phone_list)
        self.pack_start(scrolled_window)
        self.phone_list.show()
