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

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。
