如何在 Flex4 中加载并运行 Flex3 SWF，反之亦然？

我有兴趣了解如何在 Flex-4 SWF 中运行 Flex-3 SWF。

我的 Flex-4 主机应用程序如下所示：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <mx:SWFLoader source="SimpleFlex3App.swf" loadForCompatibility="true"/>

</s:Application>

这是 Flex-3 应用程序：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="400" height="400">

    <mx:Script>
        <![CDATA[

            private function onClick():void
            {
                labelField.visible = true;
            }   

        ]]>
    </mx:Script>

    <mx:Button label="Click Me" click="onClick();" horizontalCenter="0" verticalCenter="-20"/>
    <mx:Label text="Clicked" visible="false" id="labelField" horizontalCenter="0" verticalCenter="20"/>

</mx:Application>

我在 SWFLoader 尝试设置桥的位置处获得一个空对象引用。我假设它没有获得 IMarshalSystemManager 实现的实例。

IMarshalSystemManager(sm.getImplementation("mx.managers::IMarshalSystemManager")).addChildBridge(_swfBridge, this);

通过使用 SWFLoader 并将 loadForCompatibility 设置为 true，我遵循了 adobe 文档：

我必须错过了一些非常简单的事情，因为我的主机和托管应用程序基本上不做任何特别的事情。

此外，是否可以采取相反的做法，在 Flex-3 中运行基于 Flex-4 的 SWF？在我看来，adobe 文档并没有明确表示是或否。

谢谢。

I am interested in understanding how to run a Flex-3 SWF inside a Flex-4 SWF.

My Flex-4 host app looks like this:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <mx:SWFLoader source="SimpleFlex3App.swf" loadForCompatibility="true"/>

</s:Application>

And this is the Flex-3 app:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="400" height="400">

    <mx:Script>
        <![CDATA[

            private function onClick():void
            {
                labelField.visible = true;
            }   

        ]]>
    </mx:Script>

    <mx:Button label="Click Me" click="onClick();" horizontalCenter="0" verticalCenter="-20"/>
    <mx:Label text="Clicked" visible="false" id="labelField" horizontalCenter="0" verticalCenter="20"/>

</mx:Application>

I get a null object reference where the SWFLoader tries to set up the bridge. I assume it does not get an instance for the IMarshalSystemManager implementation.

IMarshalSystemManager(sm.getImplementation("mx.managers::IMarshalSystemManager")).addChildBridge(_swfBridge, this);

By using the SWFLoader and setting loadForCompatibility to true I was following the adobe documentation:

I must be missing out on something very simple as both, my host and hosted apps, basically don't do anything special.

Further, is it possible to do the opposite and run a Flex-4 based SWF inside a Flex-3 one? In my opinion the adobe doc does not clearly say yes or no.

Thanks.
