From: Martin Krischik on 15 Jan 2008 02:54 I guess we are now at: +--------------------------------+ | Ada GUI Thick bindings | (4) +--------------------------------+ | Ada GUI Thin bindings | (3) ---------------------------------+ | Convention C abstraction layer | (2) +------+--------+-------+--------+ | X11 | Gtk+ | QT | Win32 | (1) | +--------+-------+ | | | Win 32 / X11 | | +-----------------------+--------+ There is just one problem here: Both Gtk+ and QT are OO libraries which are not all that compatible with the Ada's OO way of live and this in turn mean that layer (2) and (3) might not be as tiny as we hope for.

GWindows is OK - but it is missing Unix support. But maybe WINE could help here. Martin -- mailto://krischik(a)users.sourceforge.net Ada programming at: http://ada.krischik.com

Some design suggestions? I have another suggestion: A GUI Library based on OpenStep [1]. Existing GUI Libraries tend to be rather complex with hundreds of classes - any binding is a huge work - especially since most GUI Libraries are OO - and binding to an OO Lib in another language is difficult. And a job without end as all libraries are constantly extended. Bare metal programming is only an option for Windows but not X11. In OpenStep all GUI work is done in Objective-C or Objective-C++ - languages which can be implemented by a pre-processor to C or C++. So here the Idea: If we create an Objective-Ada pre-processor we are done. And the Mac-Ada users would love it ;-).
