[PyKDE] Getting control over the Tab key

At least they never appear in keyPressEvent(), neither for the main
widget nor for the widget in focus.

I tried that, but how does one define an event filter in Python?
Here is what I tried:

  class FilterObject(QObject):

      def eventFilter(self, object, event):
	  sys.stderr.write(repr(object) + ':' + repr(event) + '\n')
	  return 1

  app = QApplication(sys.argv)
  ...
  app.installEventFilter(FilterObject())
  ...
  app.exec_loop()

This doesn't crash, but doesn't do anything either, the event filter routine
is never called.
