Thanks for the feedback Chris. We had discovered this route into the LCL documentation already. It's convenient, if rather spartan at present :-) We are investigating the use of Lazarus/LCL for some work here and if we do plunge in and use it in a production environment we would certainly contribute what information we can as we learn more about it. However what I was looking for right now was more do to with internal the design and structure of the LCL from an LCL developer's point of view rather than just the API and class definitions from an LCL user's point of view. For example, at present we're trying to learn what we need to know to be able to fix some internal LCL/GTK bugs (fixes for which would of course be fed back upstream). One of these: http://www.freepascal.org/mantis/view.php?id=9676 is a prime case in point. We have managed to refine our understanding of what the problem is but fixing it is going to require quite a bit more knowledge of GTK (which we're working on) and LCL's internal interfaces API that drives it. Thanks again for your feedback. Cheers, Bruce. _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
