How do I set Children Equal Distance Apart?

Question

I am trying to do something like this:
My Code
function drop(e:MouseEvent):void {
     if (e.target.hitTestObject(ObjectsBar)) {
     ObjectsBar.addChild(DisplayObject(e.target));
    */Then how do I make it so all the children added are equal distance apart? I know I can set the X coordinates for each one,
but I want it so that the objects can be added in any sequence and then be set to equal distance apart./*

Answer 1

var nextX:Number=0;
var gapX:Number=10;
function drop(e:MouseEvent):void {
     if (e.target.hitTestObject(ObjectsBar)) {
     ObjectsBar.addChild(DisplayObject(e.target));
  e.target.x=nextX;
nextX+=e.target.width+gapX;
