这个例子的IconManager封装在了一个SWC里，下面是它的Class源代码： /* Copyright (c) 2008 EverythingFlex.com. http://code.google.com/p/everythingflexairlib/ Permission is hereby granted,free of charge,to any person obtaining a copy of this software and associated documentation files (the “Software”),to deal in the Software without restriction,including without limitation the rights to use,copy,modify,merge,publish,distribute,sublicense,and/or sell copies of the Software,and to permit persons to whom the Software is furnished to do so,subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

看看这段代码： [Embed(source="assets/Aqua.png")] private var icon1:Class; [Embed(source="assets/alpha.png")] private var icon2:Class; private var _sysTray:SystemTrayIcon; private var _notifyTimer:Timer; //监听图标闪动 private var _state:int=0; //闪动状态 private var _bitmapDataArray:Array = []; //系统任务栏图标数组 /** 设置任务栏监听 **/ private function init(){ _notifyTimer = new Timer(500); _notifyTimer.addEventListener(TimerEvent.TIMER,onNotify); //监听Timer触发有新消息时任务栏闪动事件 /** 设置任务栏图标 **/ initSystenTray(); //初始化任务栏图标 _notifyTimer.start(); } /** * *初始化任务栏图标 * * */ private function initSystenTray():void{ /** 初始化任务栏菜单 **/ var iconMenu:NativeMenu = new NativeMenu(); var showMenuItem:NativeMenuItem = iconMenu.addItem(new NativeMenuItem("显示主窗体")); var settingMenuItem:NativeMenuItem = iconMenu.addItem(new NativeMenuItem("设置...")); iconMenu.addItem(new NativeMenuItem("-",true)); var exitMenuItem:NativeMenuItem = iconMenu.addItem(new NativeMenuItem("退出程序")); exitMenuItem.addEventListener(Event.SELECT,onExitApp); /** 初始化任务栏显示图标 **/ _bitmapDataArray[0] = (new icon1()).bitmapData; _bitmapDataArray[1] = (new icon2()).bitmapData; NativeApplication.nativeApplication.icon.bitmaps = [_bitmapDataArray[0]]; /* *绑定菜单、提示信息 **/ _sysTray = NativeApplication.nativeApplication.icon as SystemTrayIcon; /**.cp 添加任务图标单击事件**/ _sysTray.addEventListener(MouseEvent.CLICK,undock); //任务栏图标点击事件 _sysTray.tooltip = "在线提示"; _sysTray.menu = iconMenu; } /** * *退出系统 * * */ private function onExitApp(evt:Event):void{ NativeApplication.nativeApplication.icon.bitmaps = []; NativeApplication.nativeApplication.exit(); } /** * *每隔500ms触发Timer状态栏闪动提醒事件 * * */ private function onNotify(evt:TimerEvent):void{ if (_state == 0) _state = 1; else _state = 0; NativeApplication.nativeApplication.icon.bitmaps = [_bitmapDataArray[_state]]; } /** * * 系统任务图标点击事件 * * */ /**.cp 有新消息则显示新消息，没有暂不处理**/ public function undock(evt:Event):void { //自己写处理代码 }?
