[flexcoders] Programatically deselecting tree branch objects

[hardaur55]

Good morning all,

I'm trying to set up a tree control so that branch items open and close
on select just as if somebody had clicked the twirly.

I've got everything taken care of but I need to find a way to
programatically deselect the branch item.

Here's the code problem:

In my Tree change event handler

public function handleTreeChangeEvent(event:Event):void
{
         //some code

if (selectedVideoId != '')
     {
         trace(selectedVideoId + " is the selected video");
     }
     else
     {
         if (videoTree.isItemOpen(selectedVideo))
         {
             videoTree.expandItem(selectedVideo, false, true);
             //**** I now need to deselect this tree item
         }
         else
         {
             videoTree.expandItem(selectedVideo, true, true);
             //****  I now need to deselect this tree item.
         }
     }
}

See the //**** comments for details on what I'm trying to do.

I very much appreciate any light anybody can shine on this, I've been
beating up google and the API docs for the last few hours with no
results.

Thanks!!

H
