摘要
本文讨论了在GTMS图文菜单规范基础上设计并实现的生成系统的系统模型和各个子系统的功能;描述了目标系统的环境,着重论述了在目标系统中引入菜单卡的优越性;介绍了屏幕定义子系统实现的自扩展方法。该生成系统为开发用户界面提供了一有用的工具。
A menu is very often used as a user interface in an interactive system. The graph-text automatic generating system is a tool for developing a pull-down menu program. It is designed and implemented on the basis of GTMS graph-text menu specifications and by referring to the theory of UIMS. The programming language mode and the interactive mode are integrated with the former as a basis to define the menu. The menu program generated makes it possible to use the graph and the text menu alternately or in a mixed way. The model and the subsytem functions of the generating system, and the tactics for analyzing the topological message of the menu are discussed. The environment of the object system, the advantage of bringing the menu card into the object system in particular, is described. The technical procedures for running the whole system and the self-expanding method for the screen-defined subsystem are also given.
