my panda3d scene editor

Hi I’ve installed PyCEGUI and downloaded your code. Executing main.py gave no response at all. I’ve run it with the console and executing it with panda’s ppython gives this result:

ImportError: No module named PyQt4.QtCore

I also ran it with my default python with the same result.
Using pythonw had no effect whatsoever: No error message but also nothing else.

I’m using windows 7 64bit. I’ve installed a running copy of panda3d which works great and python 3.2 as well as python 2.7. The installer of PyCEGUI detected python 2.7 on my pythonpath and I installed PyCEGUI in the directory the installer suggested.

What can I do?
