show two dialogs on top of each other using java swing

Question

i have a situation where i show a dialog where user has to fill some menus and then press OK. It works fine, but now i have another button on this dialog that if user wants to add some certain value, i want another dialog to popup where user fills the additional value and while pressing ok, this dialog disappears and user comes back to the main dialog.

I have tried this, but every time i call the new dialog, the focus does not go away from the main dialog, how can i do such a task.

Is there any relevant example or what is the proper way of doing such things.

EDIT:

public static class EdgeMenu extends JPopupMenu {
        // private JFrame frame; 
        public MyMenu(final JFrame frame) {
            super("My Menu");
            // this.frame = frame;

            this.addSeparator();
            this.add(new EdgePropItem(frame));           
        }  
    }  



 //this shows the first dialog, another class because i have some other  
 //functions to be performed here  

    public static class EdgePropItem extends JMenuItem{
            //...       

            public  EdgePropItem(final JFrame frame) {  
                super("Edit Properties");
                this.addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent e) {
                        EdgePropertyDialog dialog = new EdgePropertyDialog(frame, edge);
                        dialog.setVisible(true);
                    }

                });
            }

        }  

and now in other dialog, in the button even listener i am trying to call another dialog:

 private void newDialogHandler(java.awt.event.ActionEvent evt) {
        MyNewDialog rdialog = new MyNewDialog(edge);
        rdialog.setVisible(true);
    }  

It appears fine, but the previous dialog, does not leave the focus, and it goes away only if i press finish/done on that dialog, what i want is the new dialog to come in focus, while pressing ok on here, focus should come back to the old main dialog, but it is not working?

maybe this code could be demonstate your issues,

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

public class SuperConstructor extends JFrame {

    private static final long serialVersionUID = 1L;

    public SuperConstructor() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setPreferredSize(new Dimension(300, 300));
        setTitle("Super constructor");
        Container cp = getContentPane();
        JButton b = new JButton("Show dialog");
        b.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent evt) {
                FirstDialog firstDialog = new FirstDialog(SuperConstructor.this);
            }
        });
        cp.add(b, BorderLayout.SOUTH);
        JButton bClose = new JButton("Close");
        bClose.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent evt) {
                System.exit(0);
            }
        });
        add(bClose, BorderLayout.NORTH);
        pack();
        setVisible(true);
    }

    public static void main(String args[]) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                SuperConstructor superConstructor = new SuperConstructor();
            }
        });
    }

    private class FirstDialog extends JDialog {

        private static final long serialVersionUID = 1L;

        FirstDialog(final Frame parent) {
            super(parent, "FirstDialog");
            setPreferredSize(new Dimension(200, 200));
            setLocationRelativeTo(parent);
            setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
            setModalityType(Dialog.ModalityType.DOCUMENT_MODAL);
            JButton bNext = new JButton("Show next dialog");
            bNext.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent evt) {
                    SecondDialog secondDialog = new SecondDialog(parent, false);
                }
            });
            add(bNext, BorderLayout.NORTH);
            JButton bClose = new JButton("Close");
            bClose.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent evt) {
                    setVisible(false);
                }
            });
            add(bClose, BorderLayout.SOUTH);
            pack();
            setVisible(true);
        }
    }
    private int i;

    private class SecondDialog extends JDialog {

        private static final long serialVersionUID = 1L;

        SecondDialog(final Frame parent, boolean modal) {
            //super(parent); // < --- Makes this dialog 
            //unfocusable as long as FirstDialog is visible
            setPreferredSize(new Dimension(200, 200));
            setLocation(300, 50);
            setModal(modal);
            setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
            setTitle("SecondDialog " + (i++));
            JButton bClose = new JButton("Close");
            bClose.addActionListener(new ActionListener() {

                @Override
                public void actionPerformed(ActionEvent evt) {
                    setVisible(false);
                }
            });
            add(bClose, BorderLayout.SOUTH);
            pack();
            setVisible(true);
        }
    }
}

Answer 2

You can achieve this as follows:

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

public class MultipleDialogs
{   
    public MultipleDialogs()
    {
        JButton btnOpen = new JButton("Open another dialog!");
        btnOpen.addActionListener(new ActionListener()
        {
            @Override
            public void actionPerformed(ActionEvent e)
            {
                JOptionPane.showMessageDialog(null, "This is the second dialog!");
            }
        });
        Object[] options = {"OK", "Cancel", btnOpen};
        int selectedOption = JOptionPane.showOptionDialog(null,
                "This is the first dialog!", "The title",
                JOptionPane.NO_OPTION, JOptionPane.PLAIN_MESSAGE,
                null, options, options[0]);

        if(selectedOption == 0) // Clicking "OK"
        {

        }
        else if(selectedOption == 1) // Clicking "Cancel"
        {

        }
    }

   public static void main(String[] args)
   {
      SwingUtilities.invokeLater(new Runnable()
      {
          @Override
          public void run()
          {
              new MultipleDialogs();    
          });
       }
    }
}

You can replace "This is the first dialog!" and "This is the second dialog!" with JPanel's which can contain any swing components you want.

Answer 3

Create the second dialog from a constructor that takes dialog and boolean as parameters and that solves the problem.
