Problem updating a window

[Scott Carlson]

What I am trying to do is have a logout frame popup once a user clicks on Logout from the menubar. This is working fine. What I want to do is once the user pushes the Logout button, I want some of the menu items on the main frame to be disabled.

Here is the code I have but it's not updating the main window called mainFrame. Any Ideas?

public class Logout extends JFrame
{
    JPanel contentPane;
    BorderLayout borderLayout1 = new BorderLayout();
    GridBagLayout logoutGridBag = new GridBagLayout();
    JButton buttonLogout = new JButton();
    JButton buttonCancel = new JButton();
 
    public Logout()
    {
        try
        {
            jbInit();
        }
        catch (Exception exception)
        {
            exception.printStackTrace();
        }
    }
 
    private void jbInit() throws Exception
    {
        contentPane = (JPanel) getContentPane();
        contentPane.setLayout(logoutGridBag);
        buttonLogout.setText("Logout");
        //Logout, return to main menu
       /////////////////////////////////////////////////////////////////
       buttonLogout.addActionListener(new ActionListener()
       {
           public void actionPerformed(ActionEvent evt)
           {   //THIS IS WHERE I AM HAVING THE PROBLEM
               mainFrame mf = new mainFrame();
               mf.mEdit.setVisible(false);  //want to disable mEdit
               mf.mView.setVisible(false);  //want to disable mView
               
               dispose();
           }
       });
       /////////////////////////////////////////////////////////////////
        buttonCancel.setText("Cancel");
        //Cancel Logout, return to main menu
        /////////////////////////////////////////////////////////////////
        buttonCancel.addActionListener(new ActionListener()
        {
            public void actionPerformed(ActionEvent evt)
            {
                dispose();
            }
        });
        /////////////////////////////////////////////////////////////////
        contentPane.add(buttonCancel,
                        new GridBagConstraints(1, 0, 1, 1, 0.0, 0.0
                                               , GridBagConstraints.SOUTHEAST,
                                               GridBagConstraints.NONE,
                                               new Insets(9, 10, 7, 3), 4, 51));
        contentPane.add(buttonLogout,
                        new GridBagConstraints(0, 0, 1, 1, 0.0, 0.0
                                               , GridBagConstraints.NORTH,
                                               GridBagConstraints.NONE,
                                               new Insets(8, 16, 4, 17), 2, 52));
    }
}

Try 'setEnabled' from the JMenuItem api.
