Abstract : File characteristics: computer program (1 file); ASCII character set. Physical description: 1 computer tape reel; 6250 bpi. System requirements: UNIX/SUN 3; TAR. This reusable software component implements a graphical user interface for browsing over the contents of an object management system. It is intended to facilitate the construction of various browsing tools by serving as a user interface component for those tools. The generic application interface and tailorable user interface provided by this component allow it to be adapted to a wide range browsing applications. They also serve to promote the portability of graphical browsing tools by insulating them for the details of the underlying graphics system. Because the details of the graphics system are hidden by an abstract application interface, tool builders need not be familiar with the intricacies of graphics packages for window system in order to use this product. The RGB is implemented in Ada, with the exception of one small routine coded in C. The current implementation uses the MIT X toolkit: Ada Language Implementation (Based on X Version 11, Release 3) as the underlying graphics system. This makes it compatible with numerous hardware platforms.
