我试图通过使用JInternalFrame附加JFXPanel来使用JavaFx 2.x和Swing应用程序

我的代码如下

public class InternalFrameWithJavafx extends javax.swing.JFrame {
/**
 * Creates new form InternalFrameWithJavafx
 */
public InternalFrameWithJavafx() {
    initComponents();

    final JInternalFrame frame = new JInternalFrame();
    frame.setTitle("test InternalFrame");
    frame.setVisible(true);        
    frame.setResizable(true);
    frame.setIconifiable(true);
    frame.setMaximizable(true);
    frame.setIconifiable(true);
    frame.setClosable(true);
    frame.setSize(800,600);
    frame.setLocation(0,0);        
    frame.setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);

    SwingUtilities.invokeLater(new Runnable() {

    @Override
    public void run() {
    final JFXPanel javafxPanel = new JFXPanel();

    BorderPane pane = new BorderPane();
    javafxPanel.setScene( new Scene(pane) {
        Text text = new Text("Hello World");

    });
    frame.getContentPane().add(javafxPanel,BorderLayout.CENTER);
    }
});        
    this.add(frame);    
}
@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">                          
private void initComponents() {

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0,400,Short.MAX_VALUE)
    );
    layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0,300,Short.MAX_VALUE)
    );

    pack();
}// </editor-fold>

/**
 * @param args the command line arguments
 */
public static void main(String args[]) {
    try {
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch (UnsupportedLookAndFeelException e) {
        //handle exception
    } catch (ClassNotFoundException e) {
        //handle exception
    } catch (InstantiationException e) {
        //handle exception
    } catch (IllegalAccessException e) {
        //handle exception
    }
    java.awt.EventQueue.invokeLater(new Runnable() {

        public void run() {
            new InternalFrameWithJavafx().setVisible(true);
        }
    });
}                 
}

我有这个例外

就我的目的而言，我必须使用JInternalFrame：如何解决此问题？

public class JavaFXApplication4 extends Application {

@Override
public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));

    Scene scene = new Scene(root);

    stage.setScene(scene);
    stage.show();
}

/**
 * The main() method is ignored in correctly deployed JavaFX application.
 * main() serves only as fallback in case the application can not be
 * launched through deployment artifacts,e.g.,in IDEs with limited FX
 * support. NetBeans ignores main().
 *
 * @param args the command line arguments
 */
public static void main(String[] args) {
    launch(args);
}
}

<AnchorPane id="AnchorPane" prefheight="200.0" prefWidth="320.0"  xmlns:fx="http://javafx.com/fxml" fx:controller="javafxapplication4.SampleController">

public class SampleController implements Initializable {

@FXML
private Label label;

@FXML
private void handleButtonAction(ActionEvent event) {
    System.out.println("You clicked me!");
    label.setText("Hello World!");
    //Here I want to swap the screen!
}

@Override
public void initialize(URL url,ResourceBundle rb) {
    // Todo
}    
}

解决方法

@FXML
private void handleButtonAction(ActionEvent event) {
    System.out.println("You clicked me!");
    label.setText("Hello World!");
    //Here I want to swap the screen!

    Stage stageTheEventSourceNodeBelongs = (Stage) ((Node)event.getSource()).getScene().getwindow();
    // OR
    Stage stageTheLabelBelongs = (Stage) label.getScene().getwindow();
    // these two of them return the same stage
    // Swap screen
    stage.setScene(new Scene(new Pane()));
}
