如何在多个场景中使用JavaFX菜单项

javafx

如何在多个场景中使用JavaFX菜单项,javafx,javafx-8,fxml,Javafx,Javafx 8,Fxml,我可能是想得太多了，这就是为什么我被难住了。我构建了一个包含多个场景的应用程序。每个都有文本字段和用户填写的复选框，然后将这些信息输出为文本文件。我可以毫无问题地切换场景，我可以使用一个按钮保存文件，该按钮调用每个控制器中基本相同的函数。我在根目录上有一个菜单栏，可以切换到不同的场景，加载默认值或以前的值，然后退出。我也希望有一个“另存为”选项。我可以将“另存为”指向将写入文件的控制器或模型，但我需要从当前场景获取数据。我想我需要能够访问当前控制器才能做到这一点 这是我的主应用程序 packag

任何帮助都将不胜感激。

我将此作为一个可能的答案发布，但对我来说似乎很复杂。简而言之，我添加了一个类，该类始终从每个场景控制器获取更新。从主Save_As，我可以简单地调用文件编写器代码。我不接受这个作为最终答案，因为它似乎过于复杂，而且有点慢

有没有人想过如何清理这个问题，让它更有效率？

我将此作为一个可能的答案发布，但对我来说似乎很复杂。简而言之，我添加了一个类，该类始终从每个场景控制器获取更新。从主Save_As，我可以简单地调用文件编写器代码。我不接受这个作为最终答案，因为它似乎过于复杂，而且有点慢

为什么不在
VistaNavigator
中保留对当前控制器的引用（这实际上是一个视图模型）？然后，您可以轻松检索当前控制器等。您可以使这些控制器都实现某种接口，该接口具有允许访问数据的方法（或从这些控制器执行保存操作所需的任何功能）。我最初使用了该接口，但最终得到了我所认为的，是不必要的代码复制。它复制了什么？为什么不在
