>>> from qt import QByteArray
>>> qb = QByteArray ()
>>> qb.duplicate ("Hello")
<qt.QByteArray instance at 0x819d7fc>
>>> qb.data()
'Hello'

But you should be able to use a Python string anywhere you need a
QByteArray, so the above shouldn't be necessary.

I'll check out the rest, but I'll have to see if I have noatun
working first - may take a little while to get to it
(dinnertime).

PyQt is supported on the PyKDE list:
