That's what I guessed already...

Can you give me an example for this (via PM if you want to)? Would it
then be possible to do something like

if python_version==2.4:
  @pyqtSignature..
else:
  <the older decorator-stuff>
def the_slot():

Does PyQt4 allow that, Phil?

Or at least
if python_version=2.4:
  @pyqtSignature
def the_slot():

And in the constructor of the class I could check wether
python_version==2.3 and then manually connect the slots?

I'd really like to have the programs work with Python2.3 and Python2.4.

Andreas
