Hello,
I am testing the current beta of (k)ubuntu 10.10 maverick meerkat and
recognized that my pyqt application stopped to work properly.
After some time of research I could tie the problem down to the following
situation:
I have a qcheckbox in a subclassed qobject and connected the sigal
statechanged which works perfectly in the previous versions. E.g. ubuntu
lucid.
I also checked if the signal works without a subclass - it does on both pyqt
versions.
There might be a problem in my code as well which was not causing malfunction
before, so please see the code below. It could also be a bug in the nerw
version?
Can you take a look into this and help me?
Thank you
Peter
