[Tkinter-discuss] Changing the label of a tix.NoteBook tab

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.
