JAVA FX - 如何将表单数据从一个窗口传递到另一个窗口？

Question

我是JavaFx的新手，在我看来这是一个常见的问题，但根据每个人开始编码答案的方式不同，这就是为什么我在这里找不到我的所以我只会问。 / p>

计划：管理诊所的软件
说明
1 - 应用程序打开，显示菜单按钮（医生，患者等）
2 - （假设）点击医生，显示一个带表格的经理窗口，查看所有医生注册到系统
3 - 在这里，有一个添加新的按钮
4 - （假设）单击addNewDoctor按钮并填写表格
5 - （这是我被困的地方）如何将这些数据发送到表格

这就是我的尝试：

这是怎么回事：
  我想弄清楚如何在javaFx中的另一个控制器的一个控制器中使用一个方法，我知道如何将值添加到表视图中，但这是发生的事情：

从addNewDoctor类（其中是带有表单的dialogBox）我从Doctor类（我在哪里创建表）中调用一个方法，在这个方法中我向表添加值，我还使用sysout在控制台上打印值（只是为了查看值是否已通过），它们是因为它们已被打印，但它没有将它们添加到表中。

但是如果我在Doctor类（表所在的位置）创建一个方法来添加一个新医生并将其链接到一个按钮，在这个窗口中它会添加一个新的医生（但我想添加来自一个新的dialogBox，控制器是addNewDoctor类）。

这是我的代码：
