[PyKDE] QWidgetFactory problems

[Eli Yukelzon]

Thanks for your reply.
I've tried to overcome the fact that closeEvent is not copied.
I tried just overwriting the attr, that didn't work. Then i tried
using 'instancemethod' to apply
the new closeEvent to ui class. No luck.

Maybe i'm missing something?

thanks in advance,

eli yukelzon
