是否可以在MXML（flex）中克隆复杂的可视对象？

Question

function setLabel():void {
    var cloneObject = UtilFunctions.clone(t_1) as VBox;
    ticketList.push(cloneObject);
    tickets.addChild(cloneObject);
}

我收到了t_1 id（id是VBox的一个属性），我想他所包含的所有子容器（所有子容器）也将被复制，然后将其保存到数组中，最后将其添加到某个视觉中容器，因此制作一些视觉对象的副本，但这不起作用，所以我想知道是否可能，我认为的另一个解决方案是将它放到模块然后动态创建模块并将它们添加到displayList你能给我一些提示吗？哪个更快？

**UPDATE**

package library
{
 import flash.utils.describeType;
 import flash.utils.getDefinitionByName;
 import flash.utils.getQualifiedClassName;

     public static function newSibling(sourceObj:Object):* {
         if(sourceObj) {

             var objSibling:*;
             try {
                 var classOfSourceObj:Class = getDefinitionByName(getQualifiedClassName(sourceObj)) as Class;
                 objSibling = new classOfSourceObj();
             }

             catch(e:Object) {}

             return objSibling;
         }
         return null;
     }

     public static function clone(source:Object):Object {

         var clone:Object;

                         }

                     }
