Hi
Im a beginner to java/jbuilder and ive been trying to build a tree where
nodes can be inserted/deleted....
Ive been trying to use examples from the web and this is what ive got

...
JTree myTree ;
DefaultMutableTreeNode rootNode = TreeNodes.getRoot() ;             // a
call to another class file
Defai;tTreeModel treeModel = new DefaultTreeModel(rootNode) ;
....
...
myTree = new JTree(rootNNode) ;
...
...
myTree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_S
ELECTION) ;
myTree.addTreeSelectionListener(new TreeSelectionListener()
{
      public void valueChanged(TreeSelectionEvent e)
      {
        DefaultMutableTreeNode node =
(DefaultMutableTreeNode)myTree.getLastSelectedPathComponent();
        parentNode = (MutableTreeNode)(node.getParent());

          if (parentNode != null)
          {
                ????????? remove node HOW???????
           }
       }
 });

OR IS THIS TOTALLY WRONG

Any help would be greatly appreciated
thanks in advance
