Java CardLayout Manager问题/困惑

我目前正在做一个我要求的项目

从那时起，我取得了很大的进步，现在我准备开始客户端程序的infoPanel部分。我已经阅读了文档和其他问题，但我还是有点困惑。我如何设置面板，你知道，工作？如何将其与JList链接（如果可以使用JList而不是组合框），然后如何确定哪些选择引用了哪张卡

非常感谢您的帮助

我会将ListSelectionListener添加到JList中，并在该listener的内部更改CardLayout显示的卡

您确实需要阅读第一篇文章，因为在那里您会看到您的add方法是错误的。考虑使用JLIST保存的字符串作为在使用面板添加CARDayDebug时使用的常数。

非常感谢您的帮助！！
