Finally got some time to get back to python after a long break, only to find that I don’t have a working copy of PyQt4. Instead of spending time on google trying to figure out whether anyone has decided to share a copy of PyQt built against Qt4.5.3, decided to build one myself. Having Windows SDK already installed on my XP proved out to be handy since the Visual Studio version I was running was still 32-bit one. Downloaded SIP4.12 source and Qt4.5.3 SDK and within few seconds the PyQt4 module was successfully added to the site-packages.
Thought of sharing the build for those of you who are planning ahead to design awesome GUIs in Maya.You may download it here
