1. Start up NonModalProblem.main, e.g.

  D:\jdk1.3.1Beta\bin\java -cp . NonModalProblem

A frame appears with a button to pop up a non modal dialog.
On my PC the non modal dialog does not move to the backgound
if the main frame is selected. However on a Sparc machine
(OS: Solaris 2.6, jdk1.3.0) the dialog does move to the background.

2. Source:

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

class NonModalProblem implements ActionListener {

  NonModalDialog dialog;
  int number;

  NonModalProblem(JFrame frame) {
    dialog = new NonModalDialog(frame);
  }

  public void actionPerformed(ActionEvent e) {
    dialog.setVisible(true);
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame("NonModalProblem");
    frame.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {System.exit(0);}
    });

    JButton button = new JButton("Dialog");
    button.addActionListener(new NonModalProblem(frame));
    button.setAlignmentX(Component.CENTER_ALIGNMENT);
    button.setToolTipText("Show dialog");

    Box box = Box.createVerticalBox();
    box.add(Box.createRigidArea(new Dimension (240, 40)));
    box.add(button);
    box.add(Box.createVerticalStrut(40));

    frame.getContentPane().add(box);
    frame.pack();
    frame.setVisible(true);
  }

  class NonModalDialog extends JDialog implements ActionListener {
    JTextField textField1;
    JTextField textField2;

    NonModalDialog(JFrame frame) {
      super(frame, "Non Modal Dialog", false);
      Box box = Box.createVerticalBox();

      box.add(Box.createRigidArea(new Dimension (240, 40)));

      JButton button = new JButton("OK");
      button.addActionListener(this);
      button.setAlignmentX(Component.CENTER_ALIGNMENT);
      box.add(button);
      box.add(Box.createVerticalStrut(20));
      setContentPane(box);
      pack();
    }

    public void actionPerformed(ActionEvent e) {
      setVisible(false);
    }
  }
}
