Thanks for that. Yes, I think it should work. However, as I offer all 
available styles to my users for selection I'd have to do this for every 
single style... and it's probably not really usable when querying them 
via QStyleFactory::keys(). I actually don't want to change them 
"hard-coded", but it seems there's no other solution...

It might simply be a bug in which case I'd gladly file a bug report, but 
I would like to hear some developer's opinions on it before I do so... I 
think it's pointless to file a bug if it's wanted behavior - for 
whatever weird reason.

@Andreas: yes, I'm sure about this. Changing the default in KDE (or any 
other desktop environment) doesn't change the situation. I haven't yet 
tried it on anything else than Linux, though.
Not using the activated() or itemActivated() signals is pointless IMHO 
because it would mean a drastic change in *many* parts of the code and 
doesn't really sound like the way to go, simply because of API 
compatibility (which according to the docs hasn't changed in this 
area)... also, note that I'm still using Qt 4 primarily.

Thanks again for your replies!
