The selection itself emits a signal when it is changed.  You can  
access it via TreeView::get_selection(), and see the documentation  
for TreeSelection::signal_changed. You could, in your signal handler,  
turn right around and unselect(), for example.

A word of warning, though: in my experience, the signal can be  
emitted at unexpected times...you can get two callbacks per selection  
event sometimes. I'm not sure why.
