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);//在Flex中获取当前窗口的长度与宽度使用下面的方法：var w = Application.application.width;var h = Application.application.height;//绝对定位TitleWindowvar myTitleWindow:MyTitleWindow= MyTitleWindow(PopUpManager.createPopUp(DisplayObject(Application.application),MyTitleWindow,true));myTitleWindow.x = (w-myTitleWindow.width)/2;myTitleWindow.y = 100;//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]" change="disDate()" minYear="2007"/>//选择日期 dateChoosefunction disDate():void{txtDate.text=fm.format(dtchoose.selectedDate.toLocaleDateString());}//flex 中添加html标记<mx:TextArea id="text" creationComplete="init()" width="248" height="59"><mx:htmlText><!--[CDATA[<input type='file'/><a href="http://www.baidu.com" mce_href="http://www.baidu.com">你哈!!!</a>]]--></mx:htmlText></mx:TextArea>//flex 带下划线的链接this.lblLink.htmlText="<a href="http://www.google.com" mce_href="http://www.google.com" target='_blank'>新 闻</a>";<mx:Label x="524" y="393" text="Hellollll" id="lblLink" rollOver="focusManager.deactivate()" color="blue" opaqueBackground="#ffffff"rollOut="focusManager.activate()" styleName="Label"creationComplete="link()"/>.Label{text-roll-over-color:red;
