??? 两个SWF间共享事件，那末这两个SWF就可以通过共享事件通信，例子是改动网上的，例如：
? public class Main extends Sprite
?{
??public var shared:EventDispatcher;
??public function Main()
??{
???var loader:Loader = new Loader();
???shared = loader.contentLoaderInfo.sharedEvents;
???shared.addEventListener("fromChild",fromChild);
???
???var url:String = "http://localhost:9080/lcds/Flex3007/Child.swf";
???loader.load(new URLRequest(url));
???addChild(loader);??
??}
??
??private function fromChild(event:TextEvent):void {
??????????? ?trace(event.text); // Good day
???????????? var replyMessage:TextEvent = new TextEvent("fromParent");
??????????? replyMessage.text = "Same to you";
??????????? shared.dispatchEvent(replyMessage);
?? }
?}
?这个是使用contentLoaderInfo的属性sharedEvents， 该EventDispatcher可用于跨安全边界交换事件，从而达到通信的目地；
? http://localhost:9080/lcds/Flex3007/Child.swf
?public class Child extends Sprite
?{
??public function Child()
??{
???var shared:EventDispatcher = loaderInfo.sharedEvents;
???shared.addEventListener("fromParent",fromParent);
???
???var firstMessage:TextEvent = new TextEvent("fromChild");
???firstMessage.text = "Good Day";
?? //child实例时，抛出事件信息“Good Day”
???shared.dispatchEvent(firstMessage);
??}
??
?? ?public function fromParent(event:TextEvent):void {
??????????????? ?trace(event.text); // Same to you
????????????? ??var label01:TextField=new TextField();
?????????????? ?label01.text=event.text;
?????????????? ?addChild(label01);
?? ??}
?}
运行：
