Help needed in selecting multiple nodes in Jtree

[Swetha Krish]

on typing the string in the text box, event must be triggered to search the Jtree for the string and make them selected .
Also when the string is deleted, the nodes in the tree must be deselected

m_searchText.getDocument().addDocumentListener(new DocumentListener()
      {
        @Override
        public void insertUpdate(DocumentEvent e)
        {
          fireDocumentChangeEvent();
        }
        @Override
        public void removeUpdate(DocumentEvent e)
        {
          fireDocumentChangeEvent();
        }
        @Override
        public void changedUpdate(DocumentEvent e)
        {
          fireDocumentChangeEvent();
        }       
      });

 private void fireDocumentChangeEvent() {
        String q = m_searchText.getText().toLowerCase();
        TreePath root = tp.tree.getPathForRow(0);
        collapseAll(tp.tree, root);
        if (!q.isEmpty())
        searchNode(q);
        tp.tree.repaint();
    }

If you check the JTree API, you'll see three methods that you'll find useful: expandRow / expandPath, and getSelectionModel. The latter returns the TreeSelectionModel which has methods to clear the selection, and to add a TreePath to the selection. To convert from row number to TreePath you can use JTree's getPathForRow method.
