JavaFX交换边界窗格'；s中心：按钮只工作一次
我现在对JavaFX有点困惑。基本上，当我运行代码时，我只能单击应用程序侧栏上的按钮一次，然后它会将中心窗格切换为我想要显示的窗格。但在那之后，ActionEvent似乎不会触发。。。我试着在处理后重新连接它们，但不起作用，我不知道出了什么问题 我花了两天的时间试图破解这个问题，我确信这是一件非常简单的事情 控制器：JavaFX交换边界窗格'；s中心：按钮只工作一次,java,javafx,fxml,Java,Javafx,Fxml,我现在对JavaFX有点困惑。基本上，当我运行代码时，我只能单击应用程序侧栏上的按钮一次，然后它会将中心窗格切换为我想要显示的窗格。但在那之后，ActionEvent似乎不会触发。。。我试着在处理后重新连接它们，但不起作用，我不知道出了什么问题 我花了两天的时间试图破解这个问题，我确信这是一件非常简单的事情 控制器： @FXML private Button fooButton, barButton; @FXML private Pane fooPane, barPane; @FXML priv

脚注：为了便于阅读，上面的代码被略微删减和修改。我从Android的剧本中汲取了一个想法。 如果知道如何到达节点的父节点，并且知道节点的fx:id，则可以使用此方法 完整代码根据按下的按钮将不同窗格加载到场景的中心。下面的代码是一个示例，显示如何加载一个窗格。如果您知道节点的父节点、节点的fx:id和节点的类型，则可以使用此方法获取任何节点 控制器代码
