PERSONALITY NEUTRAL GRAPHICS SUBSYSTEM

A graphics management system resident in a computer operating system provides a generic graphics interface which allows application programs written to operate with various specific graphical user interfaces, to operate on a non-native graphical user interface. The graphics management system includes a common graphical user interface (GUI) which receives graphics related application programming interface (API) calls from the application programs, and transforms the various types of graphics API calls native to a particular GUI, into a generic format compatible with a personality neutral graphics engine. The personality neutral calls are then passed from the CGUI to the personality neutral graphics engine which services the calls, and controls the drawing of lines, circles and other drawing tasks for each of the windows presented on the display. The present invention allows users to "port" application programs written for one GUI, to a computer system operating a different GUI.
