Gordon;Opps my bad; to early in the morning;I read to much into this,He needed
item_button.label = "As";override protected function updateDisplayList({ super.updateD ... item_button.move(0, 0); item_button.setActualSize( item_button.measuredWidth, item_button.measuredHeight);
Heh, sorry about that but, what I said still does pertain to the border. ;-)Peace, MikeOn 8/15/06, Gordon Smith <

A general rule in Flex layout management is
that children get positioned and sized by their parents. I suspect that the
reason you don't see anything is that item_button has a width and height of 0
by default.
If you extend UIComponent, then it is your
responsibility to position and size all of your component's children (in this
case, item_button) in an override of updateDisplayList().
When you extend HBox, HBox's override of
updateDisplayList() implements the horizontal box layout algorithm for the
children.
