Henning,

I missed your email on the list, so I am late to reply.  I for one am 
very interested in a Python editor.  I have downloaded your sample 
code and plan to study it with a view of learning about the plain 
textEdit.  

As a start, I started playing with the demo edit program and ma really 
impressed with it. I've noticed that typing "print{" gets corrected 
and interpreted as "print()".  Very pleasing, particularly as my 
eysight is too poor to distinguish between the curly bracket "{" and 
the ordinary bracket "(" without using magnifying glass!  

My interest in Qt is rather limited - I want to further improve the 
GUI I wrote for my Python program for structural analysis of 
engineering structures (the book and the program are under GPL).  

In spite of my lack of knowledge of Qt and PyQt, I hope to gain 
considerably by studying your code.  I have not noticed if it is GPL 
or similar.  Would you please clarify.

Thank you for the fine piece of work - a pleasure to browse it!

OldAl.
