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( new tray()).bitmapData;
SystemTrayIcon(NativeApplication.nativeApplication.icon).tooltip= this .title;
SystemTrayIcon(NativeApplication.nativeApplication.icon).addEventListener(MouseEvent.CLICK, undock);
SystemTrayIcon(NativeApplication.nativeApplication.icon).menu=createSystrayRootMenu();
}
}
private function 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= new NativeMenu();
var openNativeMenuItem:NativeMenuItem= new NativeMenuItem( "Open" );
var exitNativeMenuItem:NativeMenuItem= new NativeMenuItem( "Exit" );

openNativeMenuItem.addEventListener(Event.SELECT, undock);
exitNativeMenuItem.addEventListener(Event.SELECT, closeApp);

menu.addItem(openNativeMenuItem);
menu.addItem( new NativeMenuItem( "" , true ));
menu.addItem(exitNativeMenuItem);

return menu;
}
//系统退出
private function 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=[];
}
