Hi Phil,
These are indeed nice results. But how is the performance of the
python implemented widgets? I've never done one myself and I wonder if
there is any visible speed difference.

By the way, are there any Python-implemented widgets available on the
net? There are some nice widgets in KDE (like Date selector), I would
like to integrate into my application. But I don't want my application
depend on PyKDE, since I want it to be portable on Unix, Mac OS X and
Windows.

mfg.
