Mina airQQ聊天 客户端篇(三)
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,并且在Flex中的事件机制比较强大(个人认为)
有改一些样式,重新看看新的效果吧:
大致的实现方式:
在WindowedApplication中包含登陆窗口和主界面,用Flex中的状态来切换,聊天窗口时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,其它貌似没了。
看下客户端的具体实现吧:
首先我们把Flex air的默认窗口样式改一改
打开 (项目名称-app.xml)文件,把注释去掉对应改成如下
<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,如下
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口文件也可以用到
接下来看看主程序(WindowedApplication)的代码,它包含了登陆窗口和主界面,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口,这点不知道为什么,要开多个窗口就是新建几个项目名称不一样就行,还有就是导出air安装包的时候将项目-app.xml文件中的ID,name,filename改掉,再安装就可以。
