| 摘要: |
| 可视化编程环境的出现给人机界面的开发带来了巨大的变化,使人机界面的实现可以通过可视化操作,以"所见即所得"的方式进行定制,并在环境的支持下生成程序代码.这种变化给人机界面的面向对象设计提出了新的问题:既然界面的实现主要不是靠手工编程,那么在实现之前还要不要进行设计?面向对象的设计阶段建立的类图还有什么用?旨在对此问题作出回答.首先论述这种条件下的人机界面开发仍然需要设计,但设计策略应当改进.然后给出针对可视化编程环境的人机界面OOD(objected-oriented design)策略.该策略使设计工作大为简化,且更为有效、更适合基于可视化编程环境的人机界面开发. |

| Abstract: |
| Visual programming environment has brought about great changes in the development of human-machine interface. It enables the developers to implement human-machine interface using visual operations by means of “hat you see is what you get? and the program code can generate automatically by the environment. This change gives rise to some new problems to object-oriented design of human-machine interface. Since the implementation of the interface does not depend on manual programming, is it necessary to design before implementation?And whd what is the use of the class diagram built at the design stage?The answers to these questions can be found in this paper.It proves that the design is necessary yetin that environment,but its strategies should be improved.The OOD(object-oriented design)strategies for the development of human-machine interface are given,which makes the OOD work much simpler simpler,more efficent and more suitable for development in the visual programming environment. |
