there is no generic code because a TreeModel is a generic data
structure, of which only you know the contents because you created it in
the first place.

use the ::foreach() method of Gtk2::TreeModel.

it's usually a bad idea to replicate data across from data structures;
the good idea is to create your data structure as a Glib::Object
subclass and implement the Gtk2::TreeModel interface on it, so you can
use it directly to populate a TreeView.
