[Gtk-sharp-list] Implementing a tree model using the Gtk.Treemodel interface

[Jeroen Asselman]

Hello,

I want to implement my own treemodel and I inherited from the
Gtk.Treemodel interface. 
This doesn't seem to work though, none of the methods in my own model is
called.

Is implementing the Gtk.Treemodel the right way to go? Or should I
inherit from a baseclass? Or is inherting from the Gtk.Treemodel not
enough.
