总结flex各种用法

 //获得屏幕的分辨率
var x:Number=Capabilities.screenResolutionX;
var y:Number=Capabilities.screenResolutionY;
Alert.show("x="+x+"y="+y);
第二种方法
Alert.show(stage.fullScreenWidth+"=="+stage.fullScreenHeight);
//获得stage（工作区）的宽、高
Alert.show(stage.stageWidth+"=="+stage.stageHeight);
//读取xml文件
private function readxml2():void
{
var urlrequest:URLRequest=new URLRequest("file/stu.xml");
var urlloader:URLLoader=new URLLoader(urlrequest);
urlloader.addEventListener(Event.COMPLETE, completehandler);
}
private function completehandler(event:Event):void
{
var xml:XML=new XML(event.target.data);
// var arr:Array=new Array(xml);
this.dg.dataProvider=xml.children();
this.tree.dataProvider=xml;
this.cb.dataProvider=xml.children();
// this.hlist.dataProvider=xml.children();
}
//flex 获得系统路径
var add:String=ExternalInterface.call("window.location.href.toString",1);
Alert.show(add);
//背景颜色不断变化
 private function changeBG():void{
var mytime:Timer=new Timer(2000);
mytime.addEventListener(TimerEvent.TIMER,changHandle);
mytime.start();
 }
 private function changHandle(e:TimerEvent):void{
this.setStyle("backgroundColor",Math.random()* 0xffffff);
 }
//获得键盘按下的键的值
public function getCode():void
{
btn.addEventListener(KeyboardEvent.KEY_DOWN, keyHandle);
}
function keyHandle(event:KeyboardEvent):void
{
Alert.show("你按下了:" + String.fromCharCode(event.charCode));
}
//动态加载不同界面
import commont.Two;
import commont.One;
var t:Two=new Two();
var o:One=new One();
private function showOne():void{
tw.removeAllChildren();
tw.addChild(o);
}
private function showTwo():void{
tw.removeAllChildren();
tw.addChild(t);
}
//flex 绑定图片
[Bindable]
[Embed(source="img/1.jpg")]
public var phone1:Class;
//日期中文标题
<mx:DateChooser id="dtchoose" x="219" y="83" dayNames="[日,一,二,三,四,五,六]" monthNames="[一月,二月,三月,四月,五月,六月,七月,八月,九月,十月,十一月,十二月]" chang
