[PySide] animate QStackedLayout?

[Frank Rueter | OHUfx]

Hi everyone,

I'm very new to Qt/PySide and am wondering if it's possible to add an 
animation effect to, let's say, QStackedLayout, for when the page 
changes. I guess it'd something similar to the way the AppStore works.

In this example I'd like to see the new button "push" the old button out 
of view when the combobox changes:

I'm happy to take a good ol' fashioned RTFM, I'm just having a hard time 
finding the right bit of information out there.

Any help would be greatly appreciated.

Cheers,
frank
