2 楼 easonet 2009-04-04  

测试了一下有两个问题不解

如何控制加载进来的SWF文件的尺寸呢？

        private function completeHandler(event:Event) : void {  
            this.loadSwfComplete = true;  
            this.width = loader.content.width;  
            this.height = loader.content.height;  
            dispatchEvent(new Event(Event.COMPLETE));  
        } 
改为
            loader.content.width = 1024;          loader.content.height = 768;
可以改变swf文件的尺寸，可是loader.content.width的单位好相关不是像素
不知道怎么转换的我709x359的FLASH被转换了152.25 和54

另外还有一个问题
private function onCompleteHandle(e:Event):void{
try{
if(externalSwfLoader.content!=null){
flashMovieClip = externalSwfLoader.content as MovieClip;
//这里得到的flashMovvieClip的结果为null 执行下条语句就报错了.
addListenersForMovieClip(flashMovieClip);
//
Alert.show("Load swf successful.please click button in swf.");
}
}catch(e:Error){
Alert.show(e.message);
}
}

不知道是不是我SWF文件的问题,能否帮忙看看,或者将这个DEMO给我发一份或者提供一下您调用的swf文件。

谢谢。
