2.X了JavaFx - 摇摆:未对外汇应用程序线程(JavaFx 2.x - Swing : N

2019-06-27 13:06发布

我试图用的JInternalFrame中附加一个JFXPanel使用了JavaFx 2.x和Swing应用程序

我下面的代码

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);
        }
    });
}                 
}

我有这样的例外

对于我而言,我必须使用的JInternalFrame:我怎样才能解决这个问题?

Answer 1:

见“的JavaFX在Swing”教程。 您正在执行应Swing线程(事件指派线程)对JavaFX的线程上运行JavaFX的操作。

幸运的是,他们从以前的错误中汲取教训,当你错误的线程上执行操作,现在抛出异常。 这是你遇到的异常。

使用Platform#runLater如该教程

Platform.runLater(new Runnable() {
        @Override
        public void run() {
          //javaFX operations should go here
        }
   });

所述的结构JFXPanel可以保留在EDT(其在该教程还示出)
