This code is all for the TreeModel, not for the TreeView, so it does not
seem relevant.
You probably want TreeView::set_cell_data_func():
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeViewColumn.html#765296845c9e9757ba405becbbc13d96
This is used in some of the gtkmm TreeView examples:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/sec-treeview-examples.html
By the way, you are more likely to get gtkmm-specific help on the
gtkmm-list mailing list.
