Question

I want to change the state of checkBox menuItems(Enabled or Disabled) for particular document not for all Documents.For example In my application, I create Multiple Documents and I want enabled the Viewspace checkbox menuItem for doc1,It was enabled for all the created Documents not for Doc1 only.Here problem is Checkbox is enabled for only Doc1 not for all.Please give me some suggestions or if possible please provide an example.

My code:

public class ResetState extends javax.swing.JFrame {
int i=0;
JTextPane textPane;
public ResetState() {
    initComponents();
    viewSpaces.setSelected(false);
}

    tabbedPane = new javax.swing.JTabbedPane();
    menuBar = new javax.swing.JMenuBar();
    file = new javax.swing.JMenu();
    create = new javax.swing.JMenuItem();
    viewSpaces = new javax.swing.JCheckBoxMenuItem();

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    file.setText("File");

    create.setText("Create");
    create.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            createActionPerformed(evt);
        }
    });
    file.add(create);

    viewSpaces.setSelected(true);
    viewSpaces.setText("ViewSpaces");
    viewSpaces.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(java.awt.event.ActionEvent evt) {
            viewSpacesActionPerformed(evt);
        }
    });
    file.add(viewSpaces);

    menuBar.add(file);

    setJMenuBar(menuBar);

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0, 400, Short.MAX_VALUE)
        .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addComponent(tabbedPane, javax.swing.GroupLayout.DEFAULT_SIZE, 400, Short.MAX_VALUE))
    );
    layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
