Support system tray icon of Air application

Question

Hi All,
I developed a widget with flash builder 4 and I exported all the project in AIR application. Then, I packaged AIR application in .exe file for Windows, and dmg file for MAC. My application works correctly for both of OS.
When I launch application on OS Windows, an image on system tray (for my application a socceer ball) appears. On the other side, on OS MAC my icon appears, but after 3 or 4 seconds it disappears and it is replaced with an other icon (probably it's a default icon of mac for this kind of application?) ...
What can I do? Thanks in advance, regards
Gianni

Answer 1

I attached files reporting images of icon on system tray. I didn't set any option on app descriptor, I used SystemTrayIcon and DockIcon APIs.
Anyway I attach part of my application code ...
windowComplete event of WindowedApplication is handled by function preInit () ...
            private function onWindowActivate():void
                if (!this.windowActivateRequest)
                    this.dock();
            private function onInvoke( event:InvokeEvent ):void
                if( event.reason == InvokeEventReason.LOGIN )
                    //do background processing...
                    trace( "Running in background..." );
                    this.windowActivateRequest = false;
                    this.dock();                   
                else
                    trace("Running on screen");
                    this.windowActivateRequest = true;
                    if (this.stage != null)
                        this.stage.nativeWindow.activate();   
            public function dock(event:Event = null):void
                stage.nativeWindow.visible = false;
                var imgObj:BitmapAsset = new trayIcon() as BitmapAsset;
                var bitmampDataTmp:BitmapData = imgObj.bitmapData;
                var arrayTmp:Array = new Array();
                arrayTmp.push(bitmampDataTmp);
                NativeApplication.nativeApplication.icon.bitmaps = arrayTmp;
            public function undock(event:Event = null):void
                this.windowActivateRequest = true;
                stage.nativeWindow.visible = true;
                NativeApplication.nativeApplication.icon.bitmaps = [];
            private function preInit():void
                try
                    NativeApplication.nativeApplication.startAtLogin = true;
                catch ( e:Error )
                    trace( "Cannot set startAtLogin:" + e.message );
                NativeApplication.nativeApplication.addEventListener( InvokeEvent.INVOKE, onInvoke );
                if(NativeApplication.supportsDockIcon)
                    var dockIcon:DockIcon = NativeApplication.nativeApplication.icon as DockIcon;
                    NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE,undock);
                    dockIcon.menu = createIconMenu();
                }else{
                    if (NativeApplication.supportsSystemTrayIcon){
                        var sysTrayIcon:SystemTrayIcon = NativeApplication.nativeApplication.icon as SystemTrayIcon;
                        sysTrayIcon.tooltip = "Stopwatch";
                        sysTrayIcon.addEventListener(MouseEvent.CLICK,undock);
                        sysTrayIcon.menu = createIconMenu();   
            private function createIconMenu():NativeMenu
                var iconMenu:NativeMenu = new NativeMenu();
                var exitCommand: NativeMenuItem = iconMenu.addItem(new NativeMenuItem("Esci"));
                exitCommand.addEventListener(Event.SELECT, chiudi);
                return iconMenu;
trayIcon is name of .png which represent ball image ...  
I try to summarize ...In MAC OS DockIcon isn' t represented by ball image ...In Windows OS everything works.
I'm sorry for disturbing you but I hope that everything is clear.
Thanks
