The problem is that a Gtk::TreeModelFilter only "wraps over" the actual 
Gtk::TreeModel, but it is still only the underlying Gtk::TreeModel 
underneath.  Getting the flags of the Gtk::TreeModelFilter is equivalent 
to getting the flags of the underlying Gtk::TreeModel.

A Gtk::TreeStore's rows can have children and is therefore not usable by 
a Gtk::IconView.  You really need to use a Gtk::ListStore with the 
Gtk::IconView.
