I've just released a draft (beta) version of a paper called "Event-Driven Programming: Introduction, Tutorial, History".
It is available at http://eventdrivenpgm.sourceforge.net/ A few years ago I was trying to learn event-driven programming. I searched the Web for an introduction to the basic concepts, but I couldn't find one. This is my attempt to fill that void. Suggestions for improvements can be sent to me at steve(at)ferg(dot)org. -- http://mail.python.org/mailman/listinfo/python-list
