个人总结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
