个人总结flex各种用法【经典】

//获得屏幕的分辨率

var?x:Number=Capabilities.screenResolutionX;

?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;

?commont.One;

?t:Two=new?Two();

?o:One=?One();

private?function?showOne():void{

tw.removeAllChildren();

tw.addChild(o);

}

?showTwo():tw.addChild(t);

}

//flex?绑定图片

[Bindable]

Embed(source="img/1.jpg")]

public??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?dateChoose

?disDate():{

txtDate.text=fm.format(dtchoose.selectedDate.toLocaleDateString());

}

?

//flex?中添加html标记

<mx:TextAreatext"?creationComplete="init()"?width="248"?height="59>

<mx:htmlText>

<![CDATA[

<input?type='file'/>

<a?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'?target='_blank'>新?闻</a>";
<mx:Label?x="524393"?text="Hellollll"?id="lblLink"?rollOver="focusManager.deactivate()"?color="blue"?opaqueBackground="#ffffff"

?rollOut="focusManager.activate()"?styleName="Label?creationComplete="link()"/>
.Label{text-roll-over-color:red;?text-decorationunderlinebackground-colorgreenfont-size12pxtext-selected-color;}

?

//flex?转向?URL

Var?url:URLRequest=new?URLRequest(“http://www.google.cn”);

navigateToURL(url,_self);//在本页打开

_blank);//在新的一页打开

?

//弹出对话框
---------非模式打开---------

PopUpManager.createPopUp(类（界面）的名称---------模式打开---------

?ep:Main=??();

PopUpManager.addPopUp(ep,255); font-size: 11pt; font-weight: bold; ">true);//界面，打开窗口父类，是否模式

PopUpManager.centerPopUp(ep);//在父类窗口居中

?

//-----Alert的用法

?test():void

{

?glow:GlowFilter=?GlowFilter();

glow.color=StyleManager.getColorName("blue"//边框颜色

glow.strength=5;

glow.alpha=0.8;

?alert:Alert=Alert.show("是否选择"提示alert.filters=[glow];

?alertHandle(event:CloseEvent):if(event.detail==Alert.YES){

lbl.text=是;

}else否<mx:Button6280"?label="Button"?click="test()"/>

?

//flex?Combobox添加?–请选择-

?loadCB(){

?arr:Array=?Array("-请选择-"for(?i:int=1;i<10;i++){

arr[i]=i;

.cb.dataProvider=arr;

}

?

?

//combobox?选择的值和下标

?selected():Alert.show(cb.selectedItem.toString()+下标:"+cb.selectedIndex);

<mx:ComboBox194cb"?creationComplete="loadCB()"change="selected()">

.btn.scaleY=1;

//flex?panel?拖动效果

?ondragStart(event:MouseEvent):Panel(event.target).startDrag();
