[PyQt] QTabWidget subclassing woes

[Hans-Peter Jansen]

Hi,

I tried to subclass QTabWidget in order to do some processing before a tab 
is displayed or left. The problem is, that my setCurrentIndex methods are 
not called, if switching tabs via keyboard (cursor left/right on linux).

Interestingly, my keyPressEvent handlers are called. Out of desperation, I 
also intercepted QTabBar, but beside key presses, the expected calls to 
setCurrentIndex are missing. I've added some shortcuts (Alt+Left/Right) to 
switch tabs programmatically, but I would like to catch all set* calls.

Do I do something stupid, or do I need to handle the key presses myself 
(which would make the whole thing less robust and less portable)?

TIA, Pete
