JavaFX同时具有多个控制器
我正在开发一个JavaFX应用程序，在制作应用程序的“仪表板”时遇到了以下问题。该申请的结构如下： 这是主控制器的菜单或“仪表板”。我遇到的问题是能否将命令从“控制面板”发送到主视图 appFrame和controlPanel的fx:id是显示这些视图的位置。如何让这两个面板（每个面板都有自己的控制器）进行通信JavaFX同时具有多个控制器,java,javafx,Java,Javafx,我正在开发一个JavaFX应用程序，在制作应用程序的“仪表板”时遇到了以下问题。该申请的结构如下： 这是主控制器的菜单或“仪表板”。我遇到的问题是能否将命令从“控制面板”发送到主视图 appFrame和controlPanel的fx:id是显示这些视图的位置。如何让这两个面板（每个面板都有自己的控制器）进行通信 <?xml version="1.0" encoding="UTF-8"?> <?import javafx.geometry.Insets?> <?im
