[PyKDE] Qtranslator problems w/ setAccel

[stuff at mailzilla.net]

Thanks for the reply Phil.  I suppose that fix you mentioned in the change
log did indeed fix the problem.  However, since I'm somewhat committed to
making things work w/ earlier versions of PyQt I created a small python
script that fixes the pyuic created file (such that translations will 
work).  Since I'm working on an open source project I have little control 
of which PyQt distributions people are using (for instance, I am using 3.8 
because it shipped with BlackAdder).

If anybody is interested in the script please email me directly 
and I will be happy to provide it.  Basically, I have a shell script which 
calls pyuic and then my python "fixer" script.  Rather than calling pyuic 
directly, I call my wrapper shell script which does everything seemlessly 
and I'm left with a python file that works well with older versions of 
PyQt.  The "fixer" script itself simply replaces lines in the 
pyuic-created module that look like this:

    self.fileNewAction.setAccel(self.__tr("Ctrl+N"))

with:

    self.fileNewAction.setAccel(QKeySequence(self.__tr("Ctrl+N")))

The explicit cast to QKeySequence fixes the problem for PyQt versions 
released prior to 12/23/2003.
