有序JList控件的设计与实现

JList控件可以显示一组相似的数据列表,但其显示的数据通常是无序的。本文详细描述了如何设计和实现有序Jlist控件,运用一个简单的应用程序示范了其设计思想。使用装饰器设计模式为已有的ListModel接口提供了更多的功能,这样可以只需对已有的应用程序进行少量的修改,就可以充分获得使用有序列表样式所带来的好处。

Designing and Implementing a Sorted JList Component

Java programmers often use the JList component to provide list views of similar data, Despite the convenience of this user interface component , a JList doesn' t sort its elements. This article describes how to produce sorted lists and uses a simple applica- tion to demonstrate concepts. The application uses the decorator design pattern to provide additional functionality to the ListModel ob- ject you already use. This allows you to use and benefit from a sorted model after making only minimal changes to your existing ap- plication code base.
