我正在构建一个 flex 应用程序，它基本上是一些网站的包装器。其中一个是谷歌文档网站，我正在尝试让 flex 允许下载或弹出窗口或允许我这样做的东西。我在网上尝试了一大堆解决方案，但都没有奏效。这是到目前为止的代码：
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="100%" height="100%"
creationComplete="onCreationComplete()">
<s:layout>
<s:HorizontalLayout/>
</s:layout>
<fx:Style source="style.css"/>
<fx:Script>
<![CDATA[
include "CustomHTMLLoader.as";
private function onCreationComplete():void
{
// ... other stuff ...
var custom:object;
custom.htmlHost = new MyHTMLHost();
}
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

和自定义类代码：
package
{
import flash.html.HTMLHost;
import flash.html.HTMLWindowCreateOptions;
import flash.html.HTMLLoader;
public class MyHTMLHost extends HTMLHost
{
public function MyHTMLHost(defaultBehaviors:Boolean=true)
{
super(defaultBehaviors);
}
override public function createWindow(windowCreateOptions:HTMLWindowCreateOptions):HTMLLoader
{
// all JS calls and HREFs to open a new window should use the existing window
return HTMLLoader.createRootWindow();
}
}
}
任何帮助，将不胜感激。
