[pygtk] gtk.CellRendererCombo usage question

[Kestas -]

Hello

I using gtk.TreeView. I added in one of many colums gtk.CellRendererCombo.
But i have problem ..
Code works good, but not as i want ..

I rendering gtkCellRendererCombo like this .. It's OK

 def make_cell_render(self):

        liststore =3D gtk.ListStore(gobject.TYPE_STRING)
        tiekejai =3D self.db.get_names_from_database() # i am getting from
database(mysql) companies names
        for t in tiekejai:
            liststore.append((t))
        self.cell =3D gtk.CellRendererCombo()
        self.cell.set_property("text-column", 0)
        self.cell.set_property('editable', True)
        self.cell.set_property('model', liststore)
        self.cell.connect('editing-started', self.text_editing_started)
        self.cell.connect('edited', self.cell_edited_cb)
        return self.cell

I created callback self.cell_edited_cb
Because i want to change combo box value ..

my callback:

 def cell_edited_cb(self, cell, path, new_text):

        model =3D self.treeview.get_model()
        iter =3D model.get_iter_from_string(path)
        k =3D self.db.tiekejo_id_by_name(new_text)
        model.set(iter, 3, new_text) # 3 it's number of column in treeview
(with CellRenederCombo)

This code changes combo box text .. And there's problem .. I need to track
not just companies names, but companies ID's .. i have company table .. with
name and and ID's and other information ...

I need somehow store additional value (companie id, not just company name)
.. because i don't want to perform search ( by using just company name
value) .. Because there's can be company by  the same name, but the address
different ..

Actually i think:

liststore =3D gtk.ListStore(gobject.TYPE_STRING)
i need to change to liststore =3D gtk.ListStore(gobject.TYPE_STRING,
gobject.TYPE_STRING) .. and somehow extract 2nd value in callback code ..
But i don't know how ..

Any help will be appropriate ..
