Here you can find some Gtkmm-related tests I wrote.

This class diagram illustrates class dependancy in Gtk::TreeView class hierarchy (at least the way I understand it). You might also want to check out an excellent GTK+ 2.0 Tree View Tutorial by Tim-Philipp Müller for very mature discussion of View-Model concepts in GTK+ 2.0.

Window hierarchy in the example:

Gtk::Window (top_level)
 |
 \__MainWindow_ui
     |
     \_Gtk::VBox
        |
        +-Gtk::ScrolledWindow
        |  |
        |  \_Gtk::TreeView (not managed)
        |
        \_Gtk::HButtonBox
           |
           +--Gtk::Button
           +--Gtk::Button
           \__Gtk::Button
	

Test source code TreeViewTest-1.4.tar.gz (also illustrates how to implement correct scrolling window adjustments calculations).
