摘要
本文讨论了怎样在X窗口系统Motif界面开发接口的基础上，通过合理封装，建立门座起重机CAD系统界面开发平台。该界面开发平台提供了比Motif更高级的界面构件，更简便实用的调用接口，使功能模块的编程人员可以采用近似自然描述的方式来编制界面，大大提高了CAD系统开发的效率。该界面开发平台的设计思想和方法对其他CAD系统也是适用的。
This paper discusses how to set up an User Interface Developing Platform for Portal Crane CAD system byencapsulation of Motif. UIDP provides programmer more advanced and complex user interface components than Motif aswell as easier and more practical programming interface, which enables programmer to design user interface with anapproximately natural description style. UIDP improves the developing efficiency of Portal Crane CAD system greatly.The principles and methods in this paper is also approperiate to other CAD systems.
