motif图形用户界面编程接口的可移植性封装

The Transplantable Encapsulation of OSF/Motif GUI

跨平台软件开发是工程实践中经常遇到的难题。采取了封装图形界面接口的方法,建立一层接口,称之为界面抽象层,当移植整个程序时,只需修改此层接口,使得工作量最少,从而较好的解决了程序移植性问题。以Alpha工作站上利用Motif开发可移植性的图形界面封装接口为例,从消息循环、界面基本组件以及事件回调等方面实现了Alpha-Unix平台到PC-Window平台跨平台软件开发,实际效果良好。

Multi-platform software development is a difficult problem frequently met in engineering practice. In practice, we adopt the method of GUI encapsulation in establishing one layer of interface called the interface abstracts layer. In transporting the whole program, the only thing to do is to revise this layer of interface, which only needs the least work load, thus better solving the problem of program transportability. On the Alpha work station, by taking the exploitation of GUI interface with Motif for example, the development in message loop, base widget of GUI interface and Event Callback is realized from Alpha-Unix's platform to PC-window's platform, and a good practical effect is obtained.
