JTree - Highlighting a different node dynamically

Question

Hello All,
I am using a JTree to display a tree hierarchy. I have a situation, in which, the Tree window should update in the sense, point to a different node ( A different node has to be selected) based on user input.
Say the tree has root and then 3 children
root
- A
- - B
- - C
- D
- E
Each hyphen indicates a level, now when the user types B in the text box I need to update the currently selected node as B, and when he types E it should update to E Automatically. I googled online in general, and also saw that the action listeners are based on some action performed on the tree... but is there any function that can be trigged externally to update the tree selected data?
Also It will be great if there is a way in which my TreeSelectionListener event is not triggered during this change.
Regards,
Sirish

you can add key listener to your text field. Then invoke the method valueForPathChanged() of tree model. For example see small piece of code
final JTree tree = new JTree();
textField.addKeyListener(new KeyAdapter(){
            public void keyReleased(KeyEvent e) {
                TreePath path = tree.getSelectionPath();
                if(path == null) return;
                tree.getModel().valueForPathChanged(path, textField.getText());
        });
