如何解决需要在舞台上改变场景的 VBox 按钮，而舞台变量在另一个方法中
这是我目前编写的代码。除了解决我的问题之外，我也很乐意接受任何关于它的批评（请记住我是新手）。第一的。我有一个舞台，我已经按照我想要的方式配置了场景，包括按钮、图像等等。 GUI 控件左侧 VBox 中的 3 个按钮，GridPane 出现在 borderpane 的中心部分。每个 GridPane 中有 5 个按钮（以及我不担心的其他装饰性东西）这 5 个按钮，在每个 3 GridPanes 上，我想打开另一个全屏窗口，或者将舞台上的当前场景更改为不同的场景（但一旦该窗口关闭，它就必须恢复到原始场景）。我如何让这些按钮打开另一个阶段？还是改变原来舞台上的场景？或者我应该让它打开一个全屏 AnchorPane 并将主舞台设置为 false？当用户单击 15 个按钮中的一个（每个屏幕 5 个）时，我希望 15 个按钮中的每一个都有不同的屏幕，因为这些屏幕中的每一个都有不同的功能。这样做的最佳方法是什么？此外，当新的舞台/屏幕/面板启动时，我需要它是用户可以访问的唯一屏幕，直到他们关闭它或返回到第一个主屏幕。这是代码。
