java - 关闭框架java后重新启用按钮

Question

所以我正在为我的项目制作一个程序。 当我单击一个按钮时，它必须打开另一个框架并使该按钮不可单击。当您关闭弹出框时，按钮必须重新启用。所以这是

我的主框架

    package Option2;

关于我的编码的任何建议都被接受。抱歉，还在学习 Java :)

Answer 1

and when i clicked a button it must open anohter frame

您不应该创建另一个 JFrame。

相反，您应该创建一个modal JDialog。在对话框关闭之前，对话框不允许您单击框架。

Any Suggestions about my coding is accepted

遵循 Java 命名约定。变量名称不应以大写字符开头。有时您会遵循此准则，有时则不会。保持一致!

不要使用 setBounds(...)。 Swing 旨在与布局管理器一起使用!
