Adding native menus to an AIR application using ActionScript

Question

Hi,
I'm working on Mac and PC with Air application.
I'd creates a class extends Menu witch goal is to create a nativeMenu.
My class is
package
    import flash.desktop.DockIcon;
    import flash.desktop.NativeApplication;
    import flash.desktop.SystemTrayIcon;
    import flash.display.BitmapData;
    import flash.display.Loader;
    import flash.display.NativeMenu;
    import flash.display.NativeMenuItem;
    import flash.display.NativeWindow;
    import flash.display.NativeWindowDisplayState;
    import flash.display.NativeWindowSystemChrome;
    import flash.display.Screen;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.events.NativeWindowDisplayStateEvent;
    import flash.geom.Rectangle;
    import flash.net.URLRequest;
    import flash.sampler.NewObjectSample;
    import mx.controls.Alert;
    import mx.controls.Menu;
    import mx.core.Application;
    import mx.core.FlexGlobals;
    import mx.core.WindowedApplication;
    import spark.components.Application;
    import spark.components.WindowedApplication;
    public class createMenuBar extends Menu
        public function createMenuBar()
         * Initializes the app after loading
        public function initWindow():void{
            // Create root menu
            var rootMenu:NativeMenu = new NativeMenu();
            // Create root submenus
            rootMenu.addSubmenu(creerMenuFichier(),"Fichier");
            rootMenu.addSubmenu(creerMenuEdition(),"Edition");
            // Attach event listener routine to root menu
            rootMenu.addEventListener(Event.SELECT, dispatchMenuCommand);
            // Assign application menu (Mac OS X)
            if(NativeApplication.supportsMenu){
                NativeApplication.nativeApplication.menu = rootMenu;
            // Assign window menu (MS Windows)
            if(NativeWindow.supportsMenu ){
                stage.nativeWindow.menu = rootMenu;
         * createMenuCommand()
         * Creates a menu command based on parameters
        public function createMenuCommand(menuContainer:NativeMenu,
            itemLabel: String, itemKey:String,itemModifiers:Array,
            itemMnemonic:int, selectHandler:Function):NativeMenuItem{
            var cmd:NativeMenuItem = NativeMenu(menuContainer).addItem(new NativeMenuItem(itemLabel));
            cmd.mnemonicIndex = itemMnemonic; // index de la lettre de rappel du raccourci par dŽfaut 0
            cmd.keyEquivalent = itemKey;
            if(itemModifiers !=null){
                cmd.keyEquivalentModifiers = itemModifiers;
            if (selectHandler !=null){
                cmd.addEventListener(Event.SELECT, selectHandler);
            return cmd;
         * createMenuSeparator()
         * Creates a menu separator
        private function createMenuSeparator(menuContainer:NativeMenu):NativeMenuItem{
            var sep : NativeMenuItem = NativeMenu(menuContainer).addItem(new NativeMenuItem("sep", true));
            return sep;
         * Creates the File menu for app
        private function creerMenuFichier(): NativeMenu{
            var mnu:NativeMenu = new NativeMenu();
            createMenuCommand(mnu, 'Changer Utilisateur','k',null, 0, hChangeUser);
            createMenuCommand(mnu, 'Verrouiller/DŽverrouiller','', null, 0, hLock);
            createMenuCommand(mnu, 'Maintenance','', null, 0, hMaintenance);
            createMenuSeparator(mnu);
            // If Mac OS X, then use Quit label
            if (NativeApplication.supportsMenu) {
                createMenuCommand( mnu, 'Quitter', 'q', null, 0, hExit); 
            // If Windows, then use Exit
            else {
                createMenuCommand( mnu, 'Fermer', 'x', null, 0, hExit);
            return mnu; 
        public function creerMenuEdition() : NativeMenu{
            var mnu:NativeMenu = new NativeMenu();
            createMenuCommand( mnu, 'Annuler', 'z', null, 0, null); 
            createMenuCommand( mnu, 'RŽpŽter', 'y', null, 0, null);
            createMenuSeparator(mnu);   
            createMenuCommand( mnu, 'Couper', 'x', null, 2, null); 
            createMenuCommand( mnu, 'Copier', 'c', null, 0, null); 
            createMenuCommand( mnu, 'Coller', 'v', null, 0, null); 
            return mnu;
         * Catch-all menu dispatcher for all menus
        public function dispatchMenuCommand(evt: Event):void {
            var menuItem:NativeMenuItem = evt.target as NativeMenuItem;
            if (!menuItem.hasEventListener('select')) { 
                Alert.show(menuItem.label + " a ŽtŽ selectionnŽ!");
         * Simple handlers for certain menu commands
        public function hChangeUser(evt: Event):void {
            Alert.show( "Vous allez changer d'utilisateur");
On main air app.mxml file I create menu with
var menu : createMenuBar = new createMenuBar();
  menu.initWindow();
application menu appear but when I work on Windows system, windows menu is not visible.
Can you help me to solve that?
Thanks

I believe you ran into an AIR limitation.  In the class header for NativeMenu it mentions:
A native menu is a menu that is controlled and drawn by the operating system rather than by your application.       AIR supports the following types of native menus:
Application menus are supported on OS X. Use the NativeApplication.supportsMenu property to test whether        application menus are supported on the host operating system. An  application menu is displayed on the Menu bar at the top of the        Mac desktop. OS X provides a default menu for every application, but  many of the menu commands are not functional. You can add       event listeners to the default items, replace individual menus and  items, or even replace the default menu entirely.       Access the application menu object using the NativeApplication menu property.
Window menus are supported on Windows and Linux. Use the NativeWindow.supportsMenu property to       test whether window menus are supported on the host operating system. A  window menu is displayed below the window title bar. The area       occupied by the menu is not part of the window stage. Applications  cannot draw into this area. Assign a menu to a window using the        NativeWindow menu property.

Use the NativeMenu.isSupported property to check if OS supports it.  There is also NativeWindow.supportsMenu property that may help you.  I hope that helps.
