Good morning, sorry for the delay, but the internet is kind of unreliable these days. I attach my proposal for the basic framework of the CGA. It seems that the three platforms Windows, Gnome and Mac, can be modelled by choosing between a control application and a document based application. In the former case there is one primary window (no multiplicity) and in the second case there are as many document windows as needed. Beyond that, for both setups there are Toolboxes (map to toolbars on Windows and to little windows on the other platforms) and Utility windows (anything else one might need). I haven't talked about Dialogs yet. I didn't find a style guide for Athena/X. David, could you point something out to me? Critics and comment appreciated, Axel. __________________________________________________________________________ Die sicherste Form der Kommunikation: E-Mails verschluesseln, Spam-Filter, Adressverifizierung, digitale Unterschrift: http://freemail.web.de
