From my experience using a tree view (not a lot, but maybe enough to 
point some things out), items are not selected automatically.  There are 
methods, such as "set_cursor()" that do modify the selection, but I 
don't think that anything is automatically selected even after 
constructing and adding items to a tree view.

This should not be necessary if you make sure that there are no calls to 
TreeView methods such as "set_cursor()" or setting the selection 
somewhere in you're code.
