It has been about 12 months since I first got involved with gtkmm (after 
trying gtk first), and I must say I found the Gtk::TreeView 
implementation confusing having come from windows and the CList.   I 
have to agree that it was daunting.  However, once I got a handle on it, 
I find it to be a very useful tool.  I love the ability to switch 
Gtk::TreeModel's in and out of the same Gtk::TreeView.  Because I have 
not had a situation that required displaying "zillions of rows", I 
cannot comment on that except to say that I don't think the display of 
that much data in a GUI makes a lot of sense in the real world.  <Bob
