java - JFrame 和 JDialog 链接

Question

我正在为 eclipse 使用 visual swing 插件 - 这就是问题所在。在我单击按钮时，它应该显示对话框(或其他 jForm，但我读过应用程序应该只使用一个 jfrom)并隐藏第一个不是问题的。但是在第二种形式上，我需要发生同样的事情，当单击按钮时，我需要显示第一种形式，然后处理第二种形式。这是代码(它可能没有很好地排序，因为我找不到绕过这个视觉 Swing 的方法)

Answer 1

我查看了您的代码并查看了您在何处创建了 JButton 和所有内容，但我没有看到任何地方已将 ActionListeners 添加到任何。如果没有 AcionListeners，JButtons 将不会在按下按钮时调用行为。我认为您需要先解决此问题，然后再阅读 Oracle Java 教程站点上的基本 Swing 教程。
