flex加载外部swf文件.doc

济南盛世动漫游戏影视专修学院 flex加载外部swf文件引自： /news/LT/188.html第一步:建立加载类CtmObjLoader,此类可以加载文件类型 图片文件或swf文件package import flash.display.DisplayObject; import flash.display.Loader; import flash.events.*; import .URLRequest; import mx.core.UIComponent; public class CtmObjLoader extends UIComponent private var ProgressHandle:Function=null; public var loader:Loader; public var _bLoaded:Boolean=false; public var _bShow:Boolean=true; /UrlRequest 加载的地址 /progressHandle 加载中的处理过程 /bShow 加载后是否显示出来 public function CtmObjLoader(UrlRequest:String=null,progressHandle:Function=null,bShow:Boolean=true) super(); if(UrlRequest)LoadThis(UrlRequest,progressHandle,bShow); public function LoadThis(UrlRequest:String,progressHandle:Function=null,bShow:Boolean=true):void RemoveChild(); loader = new Loader(); _bShow=bShow; ProgressHandle=progressHandle; configureListeners(loader.contentLoaderInfo); if(_bShow)addChild(loader);/如果需要显示，则addchild 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; public function RemoveChild():void if(_bLoaded) try DeleteListeners(loader.contentLoaderInfo); loader.unload(); if(_bShow)removeChild(loader); loader=null; _bLoaded=false; catch(e:Error)throw new Error(Define ObjLoader Remove Error) private function configureListeners(dispatcher:IEventDispatcher):void dispatcher.addEventListener(Event.COMPLETE, completeHandler); dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); if(ProgressHandle!=null)dispatcher.addEventListener(ProgressEvent.PROGRESS, ProgressHandle); 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); private function httpStatusHandler(event:HTTPStatusEvent):void dispatchEvent(new Event(HTTPStatusEvent.HTTP_STATUS); private function ioErrorHandler(event:IOErrorEvent):void dispatchEvent(new Event(IOErrorEvent.IO_ERROR); 第二步:建立加载flash as3 swf文件类/此类专提供flash as3 swf文件加载,flex swf不需要,当然也可以写成一个类,我习惯这样package import flash.display.MovieClip; public class mySwfLoader extends CtmObjLoader public function mySwfLoader(UrlRequest:String=null, progressHandle:Function=null, bShow:Boolean=true) super(UrlRequest, progressHandle, bShow); public function get movieClip():MovieClip if(!_bLoaded)return null return content as MovieClip; 第三步:建立flex主文件1mainforflex.mxml加载flex swf外部文件用 第四步:建立flex swf子文件flexchild.mx
