You want to wrap the GtkTreeModelFilter you create here in a
GtkTreeModelSort.  See the API documentation here:

  http://pygtk.org/docs/pygtk/class-gtktreemodelsort.html

To the constructor of gtk.TreeModelSort you want to pass in self.filter
as child model.  Then set the resulting "sort model" as model to show in
the tree view.
