Air实现系统托盘功能

最近做的一个应用类似于QQ，如果用户已经登录，关闭的时候自动最小化到系统托盘位置 主要实现如下:
1,添加窗体的closing事件，在事件处理中阻止系统默认的关闭事件

[Embed(source="resources/images/logo/tray.png")]

public static const tray:Class;

private var trayImage:BitmapData;

private function initTray():void {

this.addEventListener(Event.CLOSING, handleClosingApplication);

if(NativeApplication.supportsSystemTrayIcon) {

trayImage=Bitmap(newtray()).bitmapData;

SystemTrayIcon(NativeApplication.nativeApplication.icon).tooltip=this.title;

SystemTrayIcon(NativeApplication.nativeApplication.icon).addEventListener(MouseEvent.CLICK, undock);

SystemTrayIcon(NativeApplication.nativeApplication.icon).menu=createSystrayRootMenu();

}

}

privatefunction handleClosingApplication(event:Event):void{

if(stage.nativeWindow.visible) {

//判断是否需要退出

if(UserGenerator.user) {

stage.nativeWindow.visible=false;

//初始化系统托盘图标

NativeApplication.nativeApplication.icon.bitmaps=[trayImage];

if(event) {

event.preventDefault();

}

}else {

exit();

}

}

}

2,初始化系统托盘右键菜单

private function createSystrayRootMenu():NativeMenu {

var menu:NativeMenu=newNativeMenu();

var openNativeMenuItem:NativeMenuItem=newNativeMenuItem("Open");

var exitNativeMenuItem:NativeMenuItem=newNativeMenuItem("Exit");

openNativeMenuItem.addEventListener(Event.SELECT, undock);

exitNativeMenuItem.addEventListener(Event.SELECT, closeApp);

menu.addItem(openNativeMenuItem);

menu.addItem(newNativeMenuItem("",true));

menu.addItem(exitNativeMenuItem);

returnmenu;

}

//系统退出

privatefunction closeApp(evt:Event):void{

exit();

}

//还原界面

public function undock(evt:Event):void {

stage.nativeWindow.visible=true;

stage.nativeWindow.orderToFront();

NativeApplication.nativeApplication.icon.bitmaps=[];

}
