AT&T Co has, as reported briefly last week (CI No 1,343), signed with Solbourne Computer Inc for the distribution of Solbourne’s C++-based Object Interface Library, a graphical user interface development system. The agreement includes Solbourne’s window manager, swm, an X Window system manager developed with the OI Library and AT&T’s C++ language. The Library makes it easier for developers to implement graphical user interface features such as windows, buttons and menus. Current development versions support both Open Look and OSF/Motif, but could be configured to conform to future user interface standards that might emerge. Source code for the OI Library and swm application is available from AT&T’s Unix Software Operation for computer vendors and software houses, who can then pass on binary versions for any system supporting the X Window System. Longmont, Colorado-based Matsushita Electric Industrial Co affiliate Solbourne, which says it has created a number of software tools with its OI Library, has been demonstrating the product at UniForum: it runs with Massachusetts Institute of Technology’S X11 Release 4 and AT&T’s C++ Language System Release 2.0.
