在我的应用程序中，当用户按下按钮时，当前窗口将隐藏/关闭并打开一个新窗口。在这个新窗口中是一个“退出”按钮。当用户点击它时，它也会关闭/隐藏当前窗口并“重新打开”父窗口。标题栏中的“x”按钮具有相同的行为。目前我通过为两个按钮/事件设置不同的代码块来解决它。由于该操作的代码基本相同，我的目标是只有一个代码块处理标题栏中的“退出”按钮和“x”按钮。JavaFX关闭窗口并通过“x”打开另一个标题栏中的按钮和窗口中的按钮
这里是我的代码至今：

此代码的工作，我想，但我希望有尽可能多的相同代码，可能在一类，这样我只能这个类调用，而不是一次又一次地重写相同的代码。对于“退出”按钮的onAction事件，我已经创建了一个类。需要哪些修改，我可以在stage.setOnCloseRequest事件上运行它？
