    import mx.skins.ProgrammaticSkin;  
    import flash.text.StyleSheet;

        public function RepeatBackground() {
        }

        override protected function updateDisplayList(w:Number,h:Number):void {  
            super.updateDisplayList(w,h);  
            
            graphics.clear();
            var b:BitmapFill = new BitmapFill();  
            b.source = getStyle("backgroundImage");;  
            b.begin(graphics,new Rectangle(0,w,h));  
            graphics.drawRect(0,h);  
            b.end(graphics);  
        }  
    }
}

使用方法也很简单，只需要设置一下css就可以了

Application
{
    backgroundImage: Embed(source="assets/bg1.gif"); 
    border-skin:ClassReference("RepeatBackground");
}
