我需要从我的 FXML 文件中定义的 JavaFx 按钮关闭我的 JDialog。我发布了由主应用程序调用的类的代码：

ExampleWindow.java

public class ExampleWindow extends JDialog 
{
@FXML
Button closeButton;

public ExampleWindow()
{
}

public void initAndShowGUI()
{
    final JFXPanel fxPanel = new JFXPanel();
    add(fxPanel);

    Platform.runLater(new Runnable()
    {
        @Override
        public void run()
        {
            AnchorPane parent = null;
            FXMLLoader fxmlLoader = new FXMLLoader();

            fxmlLoader.setRoot(this);
            try {
                parent = fxmlLoader.load(getClass().getResource("WindowControlPanel.fxml"));
            }
            catch (IOException e) {
                e.printStackTrace();
            }

            scene = new Scene(parent);
            fxPanel.setScene(scene);
        }
    });
}

public void onAction(ActionEvent ac)
{
this.dispose();
}

}

方法 onAction 由 JavaFx Button 调用（在 FXML 文件上）

窗口控制面板.fxml

<AnchorPane id="AnchorPane" fx:id="windowPanel" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="50.0" prefWidth="1024.0" style="-fx-border-color: white, grey; -fx-border-width: 2, 1; -fx-border-insets: 0, 0 1 1 0" xmlns:fx="http://javafx.com/fxml" fx:controller="ExampleWindow">
<children>
<FlowPane alignment="CENTER_RIGHT" columnHalignment="CENTER" prefHeight="50.0" prefWidth="1024.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
  <children>
    <Button fx:id="closeButton" mnemonicParsing="false" onAction="#onAction" prefHeight="35.0" prefWidth="100.0" text="Close">
      <FlowPane.margin>
        <Insets bottom="5.0" left="20.0" right="20.0" top="5.0" />
      </FlowPane.margin>
    </Button>
  </children>
</FlowPane>
</children>
</AnchorPane>

当我按下 closeButton 时，方法 onAction 被正确调用，但我的 JDialog 没有关闭。有任何想法吗？我哪里错了？
