Using property() to extend Tkinter classes but Tkinter classes are old-style classes?

Michele and Terry,

Michele - your technique is *exactly* what I was searching for (and
works well so far!). Terry - your explanation why Tkinter still uses old
style classes (for compatibility with existing code) makes sense.

Thank you both.
