clicked button brings object to front

hi guys,

so I currently have a set of buttons that when clicked, make certain objects visible. These objects are layered on top of each other and I want to bring each to the front when its button is clicked, but I'm struggling with the code snippets for "bring to front" - I'm pretty new to actionscript so the Child stuff is a little confusing

basically what I'm looking for is this:

button.addEventListener(MouseEvent.CLICK, showobject);

function showobject(event:MouseEvent):void

{

  *** code to bring the object to front ***

}

THANKS!
