Re: [computer-go] Event-driven programming

[Thomas Johnson <thomas_johnson@xxxxxxx>]

I think that you may be confusing event-driven programming with the
subject/observer pattern. Event driven programming is "A kind of
program, such as a graphical user interface, with a main loop which just
waits for events to occur. Each event has an associated handler which is
passed the details of the event, e.g. mouse button 3 pressed at
position" (ref:
http://wombat.doc.ic.ac.uk/foldoc/foldoc.cgi?event-driven). I may not be
understanding your approach, but I can't think of a program structure
where the main loop of the program sits idle and waits for events.

The subject-observer design pattern, which is described at
http://sern.ucalgary.ca/courses/SENG/609.04/W98/lamsh/observerLib.html
as well as in the classic "Gang of Four" Design Patterns book (Design
Patterns by Gamma, Helm, Johnson, and Vlissides) sounds closer to what
you are describing.
