In short: don't.
This issue is most probably due to parsing deficits in pylupdate4 (which
is still C++ inherited from lupdate). Don't defy it too much..
Your best bet is to adhere to the pyuic4 standard (e.g. check
resource/ui.py). In order to reduce your typing needs, it's common to
add a tr method to your classes, that may look like this:
def tr(self, msg):
return QtGui.QApplication.translate("YourClass", msg, None,
QtGui.QApplication.UnicodeUTF8)
That way, you have full control, and you can be sure, that translations
work in almost all contexts, which might not always be the case
otherwise (e.g. to trust on QWidget's tr implementation (please correct
me if I'm wrong, Phil)). Again pyqt4ref.html has a paragraph about this
very topic.
