[sonyerricsonk750i]

Hi,

I gone through many codes on internet but wasnt able to understand how can i do that.
i want to add JCheckbox to my Jtree.
How can i do that?

help is appreciated.


Here is my code for JTree

    DefaultMutableTreeNode node;
    File[] roots = File.listRoots();
    for (int k=0; k<roots.length; k++)
    {
      node = new DefaultMutableTreeNode(new IconData(ICON_DISK, null, new FileNode(roots[k])));

      top.add(node);
      node.add( new DefaultMutableTreeNode(new Boolean(true)));
    }

    m_model = new DefaultTreeModel(top);
    m_tree = new JTree(m_model);
    m_tree.putClientProperty("JTree.lineStyle", "Angled");

    TreeCellRenderer renderer = new 
    IconCellRenderer();
    m_tree.setCellRenderer(renderer);

    m_tree.addTreeExpansionListener(new 
    DirExpansionListener());

    m_tree.addTreeSelectionListener(new 
    DirSelectionListener());

    m_tree.getSelectionModel().setSelectionMode(
    TreeSelectionModel.SINGLE_TREE_SELECTION); 
    m_tree.setShowsRootHandles(true); 
    m_tree.setEditable(false);

    final JScrollPane s = new JScrollPane();
    s.getViewport().add(m_tree);
