将JPanel克隆到另一个JFrame中

Question

我想将JPanel从<{1}} A 克隆到JFrame B 。

我研究了有关深度克隆的http://www.agiledeveloper.com/articles/cloning072002.htm并遵循了指南。 但JFrame克隆JFrame后，add() B 仍为空白

后来我在Duplicating a JPanel - (Copy JPanel's static image to different JPanel)找到了一个类似的问题，但答案并不是我想要的，因为我的jpanel涉及用户互动，这不应该只是一个图像。

任何人都可以给我一个提示吗？

JframeA.java

JPanel

JframeB.java

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;


public class JframeA extends JFrame {

    private JButton addToSecondFrame;
    private JframeB secondFrame = new JframeB();
    ;
    private SomeJPanelClass myJPanelOri = new SomeJPanelClass();
    private SomeJPanelClass myJPanelClone;

    public JframeA() {
        setTitle("cloning JPanel");
        setSize(500,500);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);

    }

    public void run() {

        addToSecondFrame = new JButton("Add to Second Frame");
        addToSecondFrame.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent e) {

                myJPanelClone = (SomeJPanelClass) myJPanelOri.clone();
                secondFrame.getContentPane().add(myJPanelClone);
                secondFrame.validate();
                secondFrame.setVisible(true);

            }
        });

        this.add(myJPanelOri);
        this.add(addToSecondFrame);
    }

    public static void main(String[] args) {
        JframeA test = new JframeA();
        test.run();
    }

}
