Now in cvs with one change.  xw??.py --> *.py (which allows access to all
the python scripts in the current directory which I believe is a better
approach).  I too noticed that you could type import xw08 (for example)
before and run it, but you could not open xw08 with the widget and run it.
Now you can.  Thanks very much for this fix to the problem.

Now in CVS (although I also hope you try out python-1.5).

Discussed elsewhere with question for you about whether you still see this
problem.

For an example of the problem, try xw08.py.  (This problem also occurs in
xw01.py, but it goes by so fast you literally cannot see it.) How do you get
access to the various pages of xw08 (and other multi-page examples)? For a
KDE solution of a similar problem, look at how kview allows you to go
forward and back between various image files using arrow keys on the
toolbar.

./pythondemos.py -fam -fflen 2 -dev png -o test.png

kview test.png.*

(Be sure to enable the toolbar so you can see the arrows used for moving
between files.) It would be nice to have something similar for the pyqt
widget to navigate between various pages of an image.  Viewing various pages
of an image is, of course, different than viewing various image files, but the
widget part of it is similar.

Yes, please use the pyqt facilities to provide page access if that is possible.
(I am assuming here that the pyqt widget has this possibility.)

If this is difficult and not obvious, then I don't mind if you put it off
until after the release.  Probably a higher priority at the moment is getting
everything working cleanly under python-1.5 (note my request for your
comments on my hack to qplplot.py so it would work under python-1.5).

Thanks once again for your help.
