推荐答案

不要使用 java.awt.Dialogjavax.swing.JDialog.而是查看 JOptionPaneshowInternal..' 开头的 code> 方法.例如

Don't use a java.awt.Dialog or javax.swing.JDialog. Instead look to the JOptionPane methods that start with 'showInternal..'. E.G.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;

public class InternalDialog {

    public static void main(String[] args) throws Exception {
        Runnable r = new Runnable() {

            @Override
            public void run() {
                // the GUI as seen by the user (without frame)
                JPanel gui = new JPanel(new BorderLayout());
                gui.setBorder(new EmptyBorder(2, 3, 2, 3));

                JDesktopPane dtp = new JDesktopPane();
                gui.add(dtp);

                ActionListener listener = new ActionListener() {

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        Component c= (Component)e.getSource();
                        JOptionPane.showInternalMessageDialog(c, "Message");
                    }
                };
                for (int ii=0; ii<3; ii++) {
                    JInternalFrame jif = new JInternalFrame();
                    dtp.add(jif);
                    jif.setLocation(new Point(ii*30, ii*20));
                    jif.setSize(200,50);
                    jif.setVisible(true);

                    JButton b = new JButton("Click me!");
                    b.addActionListener(listener);
                    jif.add(b);
                }

                // TODO!
                gui.setPreferredSize(new Dimension(280, 150));
                gui.setBackground(Color.WHITE);

                JFrame f = new JFrame("Demo");
                f.add(gui);
                // Ensures JVM closes after frame(s) closed and
                // all non-daemon threads are finished
                f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                // See http://stackoverflow.com/a/7143398/418556 for demo.
                f.setLocationByPlatform(true);

                // ensures the frame is the minimum size it needs to be
                // in order display the components within it
                f.pack();
                // should be done last, to avoid flickering, moving,
                // resizing artifacts.
                f.setVisible(true);
            }
        };
        // Swing GUIs should be created and updated on the EDT
        // http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html
        SwingUtilities.invokeLater(r);
    }
}
