Ah, of course. Tk configure methods aren't just setters, they're also two
kinds of getter! A silly oversight on my behalf.

Thank you very much for taking the time to explain / explore these variations.
It feels like there's certainly some scope for a bit of polish in the Tix
implementation, with NoteBook.pageconfigure not exposed and
PanedWindow.paneconfigure broken! Perhaps it is a low priority because, as I
understand, with upcomming versions of Tk, and something called Ttk, Tix may
become somewhat obselete anyway.
Thanks again for all your input.
