I am having trouble not being able to see a JCheckBoxMenuItem on a JOptionPane. It Checks when you click it it just isn't visible. In addition when turning on the XP Theme in windows it completely disappears except for the text assigned to the JCheckboxMenuItem. I'm including the source:

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

public class JOptionPaneExamples {    
    public static void main(String[] args) {
       new Samp206GUI();
    }
}

class Samp206GUI {
   JLabel label;
   public Samp206GUI(){
     //Create a new JFrame object
     JFrame theFrame = new JFrame();
     theFrame.setSize(200,57);
     theFrame.setTitle("My Example");
                     
     //Create a JButton
     JButton buttonA = new JButton("JButton in Windows L&F");
     theFrame.getContentPane().add(buttonA);
               
     //Set the L&F for the GUI
     String plafClassName =
        "com.sun.java.swing.plaf." +
           "windows.WindowsLookAndFeel";
     try{
        UIManager.setLookAndFeel(plafClassName);
      }catch(Exception ex){System.out.println(ex);}
       
      //Cause the L&F to become visible.
      SwingUtilities.updateComponentTreeUI(theFrame);

     //Make the whole thing visible
     theFrame.setVisible(true);
     
     //Call JOptionPane
     buttonA.addActionListener(
       new ActionListener(){
         public void actionPerformed(ActionEvent e){
            JDialog m_dialog = null;
            JOptionPane pane = new JOptionPane("Transmit records",
                                JOptionPane.PLAIN_MESSAGE,
                                JOptionPane.OK_CANCEL_OPTION);
            JCheckBoxMenuItem deleteConfirm = new JCheckBoxMenuItem("Delete records from Table");            
            pane.add(deleteConfirm, 1);
            JDialog confirmDialog = pane.createDialog(m_dialog, "Confirm Transmit");
            confirmDialog.show();
             System.exit(0);
         }//end actionPerformed()
       }//end new ActionListener
     );//end addActionListener
     
     // close the JOptionPane
     theFrame.addWindowListener(new WindowAdapter(){
       public void windowClosing(WindowEvent e){
         System.exit(0);}});
   }//end constructor
 }//end GUI class

I can see the JCheckBoxMenuItem on my Windows XP/ Java 5.0 laptop and it also lets me check/ uncheck if I run your code. Can you explain the problem in more detail?

BTW instead of show () you should use setVisible ( true ) as the former is deprecated.

Thanks on the setVisible, I can check and uncheck but with the windows look and feel on I don't see the checkbox - I see the checkmark show up when I click the checkbox but the square for the box isn't there. If I turn xptheme on then the whole thing is dicolored but the text is there.  I am running the same as you as far as environment is concerned.

Ok didn't understand that aspect of it, it shows on without the windows look and feel. If I use a regular checkbox it's moved off way to the right. I'm awarding the points as is just curious if you know a way to do it with a checkbox - are gridbox layouts or something similair possible in a JOptionPane?

For such customized dialog boxes, I would say a modal JDialog is a better option - I won't use JOptionPane as you can't do much with it.

Menu items are usualy used with menus and not as stand alone....
