You are not supposed to put any code in there.

Yes, just use the signal/slot mechanism of Qt Designer to generate the 
slots (don't bother that they have C++ names) and just write your Python 
  (!, no C++-to-Python translation) into the editor of Designer. The 
functions are saved in the .ui.h file, which will be scanned by pyuic 
and added to your Python class. You might also want to add the -x switch 
to pyuic, so that it adds code to show the class (but I do not know 
whether this works, because I never used it).
But remember, the normal way of using those Qt Designer generated files 
is to subclass them, if you want to do something more complex.

If you have more questions, maybe you want to have a look at the 
PyQt/PyKDE mailing list (addresses are on the PyQt page, 
www.riverbankcomputing.co.uk)
