How to remove folder and leaf icons from a tree

Question

Hi,
I know how to remove when we have a mx component i.e.,
<mx:Tree folderOpenIcon={null} ...../> similarly for
closed and default leaf icon.
But how do i achieve this from an action script like say i
have,
var tree:Tree = new Tree();
tree.setFolderOpenIcon(null); ///is there something like this
or any other alternative.
Please advice.
Thanks,
Lucky

Answer 1

the folderOpenIcon is a style so you have to set it with the
setStyle method
try:
tree.setStyle("folderOpenIcon",null);
