I think it translates to something like this:

---------------------------------------------------------------------------------------
enum Columns { ID, NAME, N_COLUMNS }

void on_treeview_row_activated (TreeView view, TreePath path, TreeViewColumn column) {
        TreeIter iter;
        bool valid = view.model.get_iter (out iter, path);
        if (valid) {
                int id;
                string name;
                view.model.get (iter, Columns.ID, out id, Columns.NAME, out name, -1);
                stdout.printf ("Row activated: ID=%d, Name=%s\n", id, name);
        }
}
