Hi, Some time ago I collected a pageful of links to the discussions on gui design in the mail archives. I just uploaded the page as is to the wiki: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?BoostDevelGui... - also I very impolitely linked to it at the *top* of the wiki BoostGUI page. I thought it might be one resource for future discussions - it feels some of the threads cover a lot of the same ground. Uh, rephrase to a more positive note: There's quite a bit there to learn or at least consider if you're thinking about the design of a modern gui toolkit! Regards, re
