Via the python mailing list:
there is an updated version of the Tkinter wrapper of the tktreectrl
widget available at :http://klappnase.bubble.org/TkinterTreectrl/index.html
The treectrl widget allows to create fancy things like sortable multi
column listboxes and hierarchical tree views. An impressive set of
screenshots of things you can do with treectrl can be found at the
treectrl project page : http://tktreectrl.sourceforge.net .
The TkinterTreectrl package makes this functionality available for
Python/Tkinter.
BTW, Tkinker has a very small binary of about 1.5 meg using Pyexe on MS Windows.
