     Hi John,
     
     good idea to talk with the gtk folks. I guess the listbox-c shows the 
direct data retrieval
     in a a nice way. But it would not only require to add columns but also all 
this editing
     and selecting based on mouse and keys. Maybe some clean extension of 
listbox-c is nicer
     than building something around treeview.

You are right.  Looking at that demo code however, 
it might be a simple matter of changing that GtkButton for a GtkEntry or 
similar widget.
I think the harder problem is the 2D issue.  I might be wrong of course.
     
     Do the gtk guys see the problem of gtktreeview with large datasets and do 
they have a plan?
     Is there a chance that something like the extended listbox-c-lazy-gtksheet 
would ever make it
     into gtk?
     

Your guess is as good as mine!  At any rate, it is more likely to get into
Gtk if we give them some positive feedback, and maybe a patch or two.
