Flex Get Width of List Item in Horizontal List
===

I have list `<s:List>` in my Flex application that is displaying its list items horizontally, like so:

    <s:List id="horzList">
      <s:Layout>
        <s:HorizontalLayout/>
      </s:Layout>

      <s:dataProvider>
        <s:ArrayList>
          <fx:String>Short Item</fx:String>
          <fx:String>Looooonnnnggggeeerrrrr Item</fx:String>
          <fx:String>A really, really, really long item for this list</fx:String>
        </s:ArrayList>
      </s:dataProvider>
    </s:List>

Using the `change` event, how can I fetch the width of one of these items in the horizontal list?

Thank you for your time.
