I guess you could use a ListSelectionListener . 我想你可以使用ListSelectionListener 。 It will generate an event every time the selection changes. 每次选择更改时，它都会生成一个事件。

Read the section from the Swing tutorial on How to Write a ListSelectionListener for more information and working examples. 阅读Swing教程中有关如何编写ListSelectionListener的部分，以获取更多信息和工作示例。
