Part of the EurographicSeminars book series (FOCUS COMPUTER)


Sapphire (the Screen Allocation Package Providing Helpful Icons and Rectangular Environments) is a very powerful window management system running on the PERQ personal workstation. Design for the system started early in 1982 and it has been a product of PERQ Systems Corporation since mid-1983. A description of the user interface for Sapphire is given in [44] while some experiments to judge the effectiveness of the progress bars is given in [43]. This paper will concentrate on the design decisions that were made during the development, how such design decisions interact and, finally, the issues that need to be addressed by future designers of window management systems.
