Hello, 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. Best regards Michael
