All of the code relating to the treeview (as opposed to the tree model)
should only be called once.

The idea here is that display (the treeview) and the underlying data model
(treemodel) are separate. You set up a treeview with columns, etc., only
once -- changes in the treemodel will then automatically be reflected in the
display.

So the only call above that you need to repeat are:

self.group_model.clear ()
self.group_treeiter =3D self.group_model.get_iter_first()
for name in name_list:
            self.treeiter =3D self.group_model.append(None,name)
