Ahh, yes, that works! Thank you!! I should indeed have looked at the source
myself.
The Tk website is often informative, but not everything is exposed by
Tkinter/Pmw.
This is also the first time I tried Pmw. A lot less verbose than Tkinter, but
it takes some time
to learn the names/meaning of various parameters. They differ from the
equivalent params in
Tkinter and are often more descriptive, but pre-existing knowledge of Tkinter
creates some "noise".
Best wishes,
Albert-Jan
