Dynamically resizing DefaultMutableTreeNode

Question

Does anyone know how to resize a DefaultMutableTreeNode after it's been created and initially sized? I have a tree that can be resized, but if I dynamically resize it so that some nodes are wider than the tree, I'd like the last few visible characters within the nodes to be replaced by three dots "..." instead of just clipping the text. The JTable does this when you resize a column.
Thanks,
Steve Sinai

I change the two lines below:
1. This: textField.text = val        to this:  textField.htmlText = val;
2.  This: return textField.text;     to this:  return textField.htmlText;
Here we go:
import flash.events.Event;
import flash.text.StyleSheet;
import mx.controls.TextArea;
public class DynamicTextArea extends TextArea
   public function DynamicTextArea(){
      super();
      super.horizontalScrollPolicy = "off";
      super.verticalScrollPolicy = "off";
      this.addEventListener(Event.CHANGE, adjustHeightHandler);
    private function adjustHeightHandler(event:Event):void{
      //trace("textField.getLineMetrics(0).height: " + textField.getLineMetrics(0).height);
      if(height <= textField.textHeight + textField.getLineMetrics(0).height){
        height = textField.textHeight;     
        validateNow();
    override public function set htmlText(val:String):void{
      textField.htmlText = val;
      validateNow();
      height = textField.textHeight;
      validateNow();
    override public function set height(value:Number):void{
      if(textField == null){
        if(height <= value){
          super.height = value;
      }else{       
        var currentHeight:uint = textField.textHeight + textField.getLineMetrics(0).height;
        if (currentHeight<= super.maxHeight){
          if(textField.textHeight != textField.getLineMetrics(0).height){
            super.height = currentHeight;
        }else{
            super.height = super.maxHeight;         
    override public function get htmlText():String{
        return textField.htmlText;
    override public function set maxHeight(value:Number):void{
      super.maxHeight = value;
