Flex中如何利用Timer类创建一个计时器的例子
By Minidxer | April 10, 2009
接下来的例子演示了Flex中如何利用Timer类，创建一个计时器。
让我们先来看一下Demo（可以右键View Source或点击这里察看源代码）：
下面是完整代码(或点击这里察看)：
Download: main.mxml
- <?xml version="1.0" encoding="utf-8"?>
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
- layout="vertical"
- verticalAlign="middle"
- backgroundColor="white"
- creationComplete="init();">
- <mx:Script>
- <![CDATA[
- private var timer:Timer;
- private function init():void {
- timer = new Timer(1000);
- timer.addEventListener(TimerEvent.TIMER, timer_timer);
- timer.start();
- }
- private function timer_timer(evt:TimerEvent):void {
- var tmr:Timer = evt.currentTarget as Timer;
- var obj:Object = new Object();
- obj.currentCount = tmr.currentCount;
- obj.delay = tmr.delay;
- obj.repeatCount = tmr.repeatCount;
- obj.running = tmr.running;
- arrColl.addItemAt(obj, 0);
- }
- ]]>
- </mx:Script>
- <mx:ArrayCollection id="arrColl" />
- <mx:DataGrid id="dataGrid"
- dataProvider="{arrColl}"
- width="100%"
- rowCount="10"
- verticalGridLines="false"
- verticalScrollPolicy="on">
- <mx:columns>
- <mx:DataGridColumn dataField="currentCount" />
- <mx:DataGridColumn dataField="repeatCount" />
- <mx:DataGridColumn dataField="delay" />
- <mx:DataGridColumn dataField="running" />
- </mx:columns>
- </mx:DataGrid>
- </mx:Application>
