I currently develop many applications in a Qt heavy C++/Python environment on Linux, porting to PC/Mac as needed. I use Python embedded in C++ as well as in a stand alone GUI. Qt is used fro xml parsing/event handling/GUI/threading and much more. Right now all my Python work is in PyQt and I wanted to see how everyone views PySide. I'm interested because it is in house and as such should support more components with hopefully better integration. What are your experiences?
I know this has been asked before, but I want to revive the conversation.
We were recently thinking about using PySide, but we haven't found any information about whether it is supported by py2exe. That's why we kept to PyQt. If you need to develop for Windows, it's safer to use good ol' PyQt :-)
As of PySide 1.0 beta (Qt 4.7.1), there is an official Windows installer that works. It doesn't include QtDesigner and other tools, only uic.
PySide currently does not run on Windows, which limits your capability. If you were developing on Linux and needed to avoid pure GPL, then PySide is a candidate.
From an API standpoint, I find the signal/slots capability feels more "Pythonic".
