Hello.
I'm having problems with KXMLGUIClient; in particular, it seems
subclassing from it does not work when multiple inheritance is involved.
See the script below. If this gets fixed, the attached example should
work as well.
(I seem to be pushing PyKDE to its limits, and I've already found three
non-working features which I need for my application. As I've said
before, I understand that you're not very inclined to fix them for KDE 3,
but what are the odds that they'll work in KDE 4? I guess my application
can live without them until then, but I'd like to know if the future
will indeed be better. I'm afraid all I can provide is working/non-working
C++/Python examples.)
