我可能在想这个，这就是为什么它让我难过。我已经构建了一个包含多个场景的应用。每个都有用户填写的文本字段和复选框，然后他们将该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来保存文件，该按钮调用每个控制器中基本相同的功能。我在根上有一个菜单栏，允许切换到不同的场景，加载默认值或以前的值，然后退出。我想在那里也有一个保存选项。我可以将Save_As指向将写入文件的控制器或模型，但我需要从当前场景中获取数据。我想我需要能够访问当前的控制器才能够做到这一点。
这是我的MainApp

非常感谢任何帮助。
答案 0 :(得分：0)
我发布这个作为一个潜在的答案，但对我来说似乎很复杂。简而言之，我添加了一个类，它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。
