这个组件是一个独立于其他组件的滚动条,可以根据Position以及其他信息实现一些功能,比如可以作为分页什么的.
<?xml version="1.0" encoding="utf-8"?> <!-- Simple example to demonstrate the HScrollBar control. --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ import mx.events.ScrollEvent; // Event handler function to display the scroll location // as you move the scroll thumb. private function myScroll(event:ScrollEvent):void { showPosition.text = "HScrollBar properties summary:" + '\n' + "------------------------------------" + '\n' + "Current scroll position: " + event.currentTarget.scrollPosition + '\n' + "The maximum scroll position: " + event.currentTarget.maxScrollPosition + '\n' + "The minimum scroll position: " + event.currentTarget.minScrollPosition ; } ]]> </mx:Script> <mx:Panel id="panel" title="HScrollBar Control Example" height="75%" width="75%" paddingTop="10" paddingBottom="10" paddingLeft="10" paddingRight="10"> <mx:Label width="100%" color="blue" text="Click on the scroll bar to view its properties."/> <mx:HScrollBar id="bar" width="100%" minScrollPosition="0" maxScrollPosition="{panel.width - 20}" lineScrollSize="50" pageScrollSize="100" scroll="myScroll(event);" repeatDelay="1000" repeatInterval="500" /> <mx:TextArea height="100%" width="100%" id="showPosition" color="blue" /> </mx:Panel> </mx:Application>
