1-首先写一个加载外部swf文件的类
package Package
{
import flash.display.DisplayObject;
import flash.display.Loader;
import flash.events.*;
import flash.net.URLRequest;
import mx.core.UIComponent;
import mx.events.FlexEvent;
public class CtmObjLoader extends UIComponent
{
private var loader:Loader;
private var ProgressHandle:Function=null;
public var _bLoaded:Boolean=false;
public function CtmObjLoader(UrlRequest:String=null,progressHandle:Function=null)
{
super();
if(UrlRequest)LoadThis(UrlRequest,progressHandle);
}
public function LoadThis(UrlRequest:String,progressHandle:Function=null):void{
RemoveChild();
loader = new Loader();
ProgressHandle=progressHandle;
//DeleteListeners(loader.contentLoaderInfo);
configureListeners(loader.contentLoaderInfo);
addChild(loader);
var request:URLRequest = new URLRequest(UrlRequest);
loader.load(request);
}
public function UnLoadThis():void{
try{
RemoveChild();
this.parent.removeChild(this);
}catch(e:Error){}
//this=null;
}
public function get content():DisplayObject{
if(!_bLoaded)return null;
return loader.content;
}
private function RemoveChild():void{
if(_bLoaded){
try{
DeleteListeners(loader.contentLoaderInfo);
loader.unload();
removeChild(loader);
loader=null;
_bLoaded=false;
}catch(e:Error){}
}
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.COMPLETE, completeHandler);
//var a:FlexEvent
dispatcher.addEventListener(FlexEvent.APPLICATION_COMPLETE, tttt);
dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
if(ProgressHandle!=null)dispatcher.addEventListener(ProgressEvent.PROGRESS,
ProgressHandle);
}
private function tttt(event:FlexEvent):void{
dispatchEvent(new Event(FlexEvent.APPLICATION_COMPLETE));
}
private function DeleteListeners(dispatcher:IEventDispatcher):void {
if(dispatcher.hasEventListener(Event.COMPLETE))dispatcher.removeEventListener
(Event.COMPLETE, completeHandler);
if(dispatcher.hasEventListener(HTTPStatusEvent.HTTP_STATUS))
dispatcher.removeEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
if(dispatcher.hasEventListener(IOErrorEvent.IO_ERROR))
dispatcher.removeEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
if(dispatcher.hasEventListener(ProgressEvent.PROGRESS))
if(ProgressHandle!=null)dispatcher.removeEventListener(ProgressEvent.PROGRESS,
ProgressHandle);
}
private function completeHandler(event:Event):void {
this.width=loader.content.width;
this.height=loader.content.height;
_bLoaded=true;
dispatchEvent(new Event(Event.COMPLETE));
//if(CmpHandle)CmpHandle
}
private function httpStatusHandler(event:HTTPStatusEvent):void {
dispatchEvent(new Event(HTTPStatusEvent.HTTP_STATUS));
}
private function ioErrorHandler(event:IOErrorEvent):void {
dispatchEvent(new Event(IOErrorEvent.IO_ERROR));
}
}
}
这个类用来加载外部swf文件[flex-flash]，当然也可以加载图片文件
2.写主文件main.mxml
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
xmlns:ns1="ManageView.*" fontSize="12">
<mx:Script>
<![CDATA[
/*
Flex 控制加载外部的swf文件[子文件为flex版]
*/
import mx.managers.SystemManager;
import mx.controls.Alert;
import Package.CtmObjLoader;
import flash.utils.setTimeout;
[Bindable]private var _CtmObjLoader:CtmObjLoader;
private var LoadedSM:SystemManager;
private function LoadSwf():void{//加载文件函数
LoadedSM=null;//子文件管理器
if(_CtmObjLoader){
_CtmObjLoader.LoadThis(''child.swf'');//child.swf为子文件名称,同级目录
}else{
_CtmObjLoader=new CtmObjLoader(''child.swf'');
_CtmObjLoader.addEventListener(IOErrorEvent.IO_ERROR,OnFailHandle);//监听失败事件
_CtmObjLoader.addEventListener(Event.COMPLETE,OnCompleteHandle);//监听加载完成事件
this.addChild(_CtmObjLoader);//将加载容器加入主程序
}
_CtmObjLoader.setStyle(''horizontalCenter'',0);
_CtmObjLoader.setStyle(''verticalCenter'',0);
}
private function OnFailHandle(e:Event):void{
mx.controls.Alert.show(''error'');
}
private function OnCompleteHandle(E:Event):void{
LoadedSM=SystemManager(_CtmObjLoader.content);
}
private function OnTestCall(e:Event):void{//响映子文件事件
Alert.show(''Child Event Call'');
}
private function MCtestCall():void{//调用子文件函数
if(LoadedSM){
try{
LoadedSM.document.TestCall(''From Parent Call'');
}catch(e:Error){
Alert.show(e.message);
}
}else{
Alert.show(''请加载文件'');
return;
}
}
private function testAddChildListener():void{//为子文件设置回调事件，如不设置，将收不到子
文件事件响映
if(!_CtmObjLoader){Alert.show(''请加载文件'');return;}
var d:DisplayObject=_CtmObjLoader.content;
try{
LoadedSM.document.addEventListener("EventGoTOParent",OnTestCall);
Alert.show(''设置成功'');
}catch(e:Error){Alert.show(e.message)}
//_Url=urltxt.text;
}
]]>
</mx:Script>
<mx:Button label="加载flex子文件" click="LoadSwf();" x="26" y="10"/>
<mx:Button label="为加载的文件设置Listener" click="testAddChildListener();" x="150" y="10"/>
<mx:Button label="测试加载的文件函数" click="MCtestCall();" x="342" y="10"/>
</mx:Application>
3.写子文件child.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="750" height="444"
applicationComplete="initApp()" styleName="Border3" fontSize="12">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
private function initApp():void{
}
public function TestCall(msg:String):void{
mx.controls.Alert.show(msg);
}
private function EventGoToParent():void{
dispatchEvent(new Event(''EventGoTOParent''));
}
]]>
</mx:Script>
<mx:Button x="327" y="148" label="向Parent通知事件" click="EventGoToParent()"/>
</mx:Application>
完成，文件都可以直接copy后编译运行
