Thanks for ur reply Grizzzzzzzzz,
                                                is there a way to identify the selected leaf from within MyTreeItemRenderer(Extends TreeItemRenderer)?
                                               If this is possible,i can add the image to the selected leaf of the tree.
Right now i am assigning images to all the leaf nodes of the tree as follows:
public  
class MyTreeItemRenderer extends TreeItemRenderer
* Override to draw a line in case current item is a leaf.
 override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):
void{ 
// Call super method 
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(super.data){
if(TreeListData(super.listData).hasChildren){
// logic for parent node comes here
else{ 
//Adding leaf Image
//Logic to add images to leaf 
myImage.source = leafImage;
myImage.x =
super.label.x;
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???
//HOW TO FIND THE SELECTED LEAF NODE FROM HERE??? SO THAT SELECTED LEAF WILL BE ADDED WITH THE IMAGE???
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???
