Heya

I'm quite new to PyQt. I'm trying to find some examples as to how to use savestate but so far I come up empty handed with python examples. Maybe I'm missing the elephant in the room so maybe point me out to it please. Most of my QT code learning experience come from zetcode and few other tutorials. Also I use pyuic4 to convert QT code to python and then study it. Now if some one could either point me to a way to set up savestate in QT Creator - then I could pyuic4 and back learn it and its all good but if Its not doable in creator here is my piece of code. If some1 could be so kind to show me few examples how I can add save/load states to it it would be great!
