[PySide] animate QStackedLayout?

Sat Apr 7 01:51:40 CEST 2012

I agree, it does seem off, which is why I'm throwing it out here to get 
some ideas on how to tackle this from more experienced peeps.

I will try to clarify what I'm after:
The idea is to have a collection of buttons per category, let's say a 
"page" of buttons. When the category is chosen via the buttons on the 
left, the requested page with buttons slides into view pushing the 
current one out of view. It's like an animated toolbox.

I like your suggestion, will investigate.

Cheers,
frank
