    • 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.
    • 驻留在计算机操作系统中的图形管理系统提供通用图形接口,其允许用各种特定图形用户界面编写的应用程序在非本地图形用户界面上操作。 图形管理系统包括通用图形用户界面(GUI),其从应用程序接收图形相关的应用程序编程接口(API)调用,并将本机的各种图形API调用转换为特定GUI的本机,调整为与 一个个性中性的图形引擎。 然后,个性中性调用从CGUI传递给服务于呼叫的个性中性图形引擎,并且控制对显示器上呈现的每个窗口的线,圆和其他绘图任务的绘制。 本发明允许用户将为一个GUI编写的应用程序“移植”到操作不同GUI的计算机系统。
