[PyKDE] How to do *INTERACTIVE* plotting with PyQt (or PyQwt)

[Peter Lipa]

Thanks, Boudewijn, for your help and insight!
It looks like we converge to the one-and-only clean solution to run
a new command window from with a pyqt shell.

That's exaclty what I've been trying to do - use the plain shell - and
failed.
Thanks for putting it in clear words. I think the embedding with MFC is not
a big problem since the MFC and python shell are very clearly separated (we
essentially
run a windows console with python inside the MFC GUI).

Thanks for your insight here. I might have tried such an alternate approach
for a few days (or longer?). That saves me some valuable time.

I think we can mangage from here. 
Thanks a lot!
