        public function Main()
        {
            super();
            for(var i:int = 0; i < array.length; i++)
            {
                var spr:Sprite = new Sprite();
    
                spr.graphics.beginFill(0x880088, 1);
                spr.graphics.drawRect(0, 0, 100, 30);
                spr.graphics.endFill();
    
                var txt:TextField = new TextField();
    
                txt.text = String(array[i]);
    
                spr.addChild(txt);
    
                addChild(spr);
    
                spr.y = i * 32;
            }

            graphics.beginFill(0xcccccc);
            graphics.drawRoundRect(0, 0, 20, 16, 4, 4);
            graphics.endFill(  );
            graphics.beginFill(0x333333);

            draw(  );
            dispatchEvent(new Event(Event.CHANGE));
        }

Volume Control

 
package{
   import flash.display.*;

            addEventListener(MouseEvent.CLICK, onClick);
            draw(  );
        }
        
        public function onClick(event:MouseEvent):void
        {
            // When user clicks the bar, set the volume

            dispatchEvent(new Event(Event.CHANGE));
        }
