怎么去掉Flex4生成的SWF加载时的进度条

方法1：

 

<?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" usePreloader="false">

 

 

方法二:

重写Preload的进度条类

 

package com.haso.flex4SH.component
{
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.ProgressEvent;

    import mx.events.FlexEvent;
    import mx.preloaders.DownloadProgressBar;

    public class pbarunsee extends DownloadProgressBar
    {
        public function pbarunsee()
        {
            super();
        }
        override public function set preloader( preloader:Sprite ):void    {
            preloader.addEventListener( ProgressEvent.PROGRESS , SWFDownloadProgress );
            preloader.addEventListener( Event.COMPLETE , SWFDownloadComplete );
            preloader.addEventListener( FlexEvent.INIT_PROGRESS , FlexInitProgress );
            preloader.addEventListener( FlexEvent.INIT_COMPLETE , FlexInitComplete );
        }
        private function SWFDownloadProgress( event:ProgressEvent ):void {
            this.visible=false;
        }

        private function SWFDownloadComplete( event:Event ):void {this.visible=false;}

        private function FlexInitProgress( event:Event ):void {
            this.visible=false;
        }

        private function FlexInitComplete( event:Event ):void
        {
            dispatchEvent(new Event(Event.COMPLETE));
        }
    }
}
