开发工具 (FlashBuilder4.7)
程序类型（Adobe Air）
Flex Air做的桌面程序，效果还挺好看的。最主要是Socket这一块，它也是异步的，而且在Flex中的事件机制比較强大（个人觉得）
有改一些样式，又一次看看新的效果吧：
大致的实现方式：
在WindowedApplication中包括登陆窗体和主界面，用Flex中的状态来切换，聊天窗体时Window组件。好友列表用树菜单
实现好友分组。好友上线时改成在线图标，收到消息时头像抖动，聊天显示实现图文混排，系统托盘。其他貌似没了。
看下client的详细实现吧：
首先我们把Flex air的默认窗体样式改一改
打开 （项目名称-app.xml）文件，把凝视去掉相应改成例如以下
<systemChrome>none</systemChrome>
<transparent>true</transparent>
上面是把默认的样式去掉了，然后新建一个WindowedApplication的皮肤。例如以下
WindowAppSkin.xml
<s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:fb="http://ns.adobe.com/flashbuilder/2009"
alpha.disabledGroup="0.5" >
<fx:Metadata>
[HostComponent("spark.components.WindowedApplication")]
</fx:Metadata> <s:states>
<s:State name="normal" />
<s:State name="disabled" stateGroups="disabledGroup" />
<s:State name="normalAndInactive" stateGroups="inactiveGroup" />
<s:State name="disabledAndInactive" stateGroups="disabledGroup, inactiveGroup" />
</s:states>
<s:Rect width="100%" height="100%" alpha="0">
</s:Rect>
<s:Rect horizontalCenter="0" verticalCenter="0"
width="{this.width-20}" height="{this.height-20}"
topLeftRadiusX="6" topRightRadiusX="6">
<s:fill>
<s:SolidColor color="#EBF2F9"/>
</s:fill>
<!-- 边框发光效果 -->
<s:filters>
<s:GlowFilter color="0x000000" alpha="0.6" blurX="7" blurY="7" strength="1" inner="false" quality="3" knockout="false"/>
</s:filters>
</s:Rect>
<!-- 主题内容 -->
<s:Group id="contentGroup" top="10" left="10" right="10" bottom="10"/>
</s:SparkSkin>
然后在主程序中引用这个皮肤 skinClass=“WindowAppSkin” ,这个皮肤文件我们在聊天窗体文件也能够用到
接下来看看主程序（WindowedApplication）的代码。它包括了登陆窗体和主界面，然后通过状态来切换界面显示
chat.mxml
<? xml version="1.0" encoding="utf-8"? >
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
skinClass="com.bufoon.skins.WindowAppSkin"
width="450" height="350" initialize="init(event)" xmlns:components="com.bufoon.components.*">
<fx:Style>
@namespace s "library://ns.adobe.com/flex/spark";
@namespace mx "library://ns.adobe.com/flex/mx";
.treeStyle{
/*去掉默认目录图标*/
folderClosedIcon: ClassReference(null);
folderOpenIcon: ClassReference(null); /*去掉叶子节点图标*/
defaultLeafIcon: ClassReference(null);
textIndent:5;
leading:5;
/*
defaultLeafIcon 指定叶图标
disclosureClosedIcon 指定的图标旁边显示一个封闭的分支节点。 默认的图标是一个黑色三角形。
disclosureOpenIcon 指定的图标旁边显示一个开放的分支节点。默认的图标是一个黑色三角形。
folderClosedIcon 关闭指定的目录图标的一个分支节点。
folderOpenIcon 指定打开的目录图标的一个分支节点。
例：三角图标改动例如以下代码使用就可以换成自己的了：
disclosureOpenIcon:Embed(source='images/a.png');
disclosureClosedIcon:Embed(source='images/b.png');
*/
}

注：主要就是这几个界面组件和Socket的操作类，还有就是Flex air同一个应用程序不能开多个窗体，这点不知道为什么。要开多个窗体就是新建几个项目名称不一样即可，还有就是导出air安装包的时候将项目-app.xml文件里的ID。name。filename改掉，再安装就能够。
