class HomeScene extends eui.Component{
        private testScroll:eui.Scroller;
 
        public constructor() {
                super();
                this.skinName = "HomeSceneSkin";
        }
        private bar:TestBar;
        public childrenCreated(){
                this.testScroll.scrollPolicyV = eui.ScrollPolicy.ON;
                let thumb:any = this.testScroll.verticalScrollBar.thumb;
                thumb.texture  = RES.getRes("thumb_png");
        }
}
