Re: 2 Questions on Tree widget

The idea is rather that when the user opens or closes a node, an
-opencommand or -closecommand is invoked and calls your code back to do
what's needed.

The x/yview methods just service the standard scrollbar protocol.
Consider this snippet from http://mini.net/tcl/LemonTree :

 Tree .t -background white -opencmd {LemonTree::open .t}
-yscrollcommand {.y set}
 pack [scrollbar .y -command {.t yview}] -side right -fill y

The additional arguments are automagically added when the scrollbar is
moved.
