Thanks for the tip, that did it for me, too.

I needed a similar modification here. 

I ask the authors, if I'm allowed to publish the PyQt variants in the 
Wiki, but unfortunately they refused.

This is quite sad, since some of their examples contain pretty nice 
(and partly dirty) tricks.

On the other hand, if somebody bought the book, the allowed me to 
share the code, if I make sure, they own it, just ask me directly.

Have a good day,
