The preferred approach is a higher-level"toolkit" of user interface components, such as menus and scroll bars. Experience with current toolkits shows the need for an object-oriented interface to these components.NeWS, the Network/extensible Window System, allows user interface components to be programmed in PostScript. Fortunately, object-oriented interfaces are natural in PostScript, and they have been used to create a toolkit with some novel properties. Among these are the use of concurrent processing and run-time inheritance of component methods."Postscript is the future of words on paper."Arthur C. Clarke10.1111/j.1467-8659.1987.tb00537.x171-179
