Rocco,

I read the above as saying that decorators are only in C++.  Not so.  They are 
implemented in Python, too.  The implementation may well be a "wrapper" of a 
C++ code, but why you or I should care?  Like you, I am new to PyQt, though 
being very  old, I am hardly new to anything... Important thing is that 
decorators are in Python and they do work in Python, even though AFAIK they 
were introduced to it recently.

You are lucky - you are a C programmer.  I am not a programmer at all, though 
I use and love Python and have programmed and sometimes taught  a whole range 
of programming languages - George II, Fortran, APL, Basic, Pascal...

So don't feel alone amongst these masters of PyQt. like Phil, Andreas etc,  
Mugs like I read with interest your mail, too!

Kind regards,
OldAl.
