Hi, So at the very end of that email that you linked, I mentioned the problem that paraview hangs when it encounters a runtime error, instead of reporting the error. I haven't had the chance to investigate the problem, but it's really annoying!
Anyway, I think your problem is just a few typos... try adding: from PyQt4.QtCore import * at the top. Also, you had commas instead of periods in two places: foo,input1 --> foo.input1 self, acceptfoo --> self.acceptfoo I debugged the problems by running your script in regular python. I commented out the callback_wrapper and then just added: import sys app = QApplication(sys.argv) before the main script begins. Doing it this way made it easy to spot the typos.
