[PySide] animate QStackedLayout?

Sat Apr 7 17:23:57 CEST 2012

Hello Frank!

I slightly changed my code to your new informations and added comments 
for better understanding;-)! I also changed the sorting method to show 
you a possibility to separe checked from unchecked checkboxes. Because I 
first thought, that multiple pages must be visible at once, I created 
two versions, but according to your mail, the second possibility will 
meet your requirements closer I guess. But the multi-version might be 
interesting for others:

Mutliple pages visible:

Only one page visible:

Easter-greetings
