Adding Mac OS X Close Behavior to AIR Application

Just a quick post because I have seen this done on other sites but it no longer is valid in AIR 1.5. Most Mac OS X applications minimize to system tray on closing the application using the “x” close button on the app. To achieve this in AIR 1.5 you will need to do the following on creationComplete event of the main application:

 // on application creation complete setup default Mac OS X behavior
 private function init():void
 {
 if (NativeApplication.supportsMenu) { // we are on a Mac
 //this.nativeWindow.addEventListener(InvokeEvent.INVOKE, handleAppInvoke);
 NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE, handleAppInvoke);
 this.nativeWindow.addEventListener(Event.CLOSING, handleAppHide);
 NativeApplication.nativeApplication.addEventListener(Event.EXITING, handleAppExit);
 NativeApplication.nativeApplication.autoExit = false;
 } else { // we are on a Windows machine
 this.nativeWindow.addEventListener(Event.CLOSING, handleAppClosing);
 NativeApplication.nativeApplication.autoExit = true;
 }
 }

// active that application
 private function handleAppInvoke(event:InvokeEvent):void
 {
 this.nativeWindow.activate();
 }

// close all open windows
 private function handleAppClosing(event:Event):void
 {
 event.preventDefault();
 for (var i:int = NativeApplication.nativeApplication.openedWindows.length - 1; i >= 0; --i) {
 NativeWindow(NativeApplication.nativeApplication.openedWindows[i]).close();
 }
 }

// hide the application instead of closing it
 private function handleAppHide(event:Event):void
 {
 if( this.nativeWindow.visible ) { // if the window is visible the event behaviour is canceld and the window is hidden
 event.preventDefault();
 this.nativeWindow.visible = false;
 }
 }

// close all open windows, remove event listener for hiding application and close applicatin
 private function handleAppExit(event:Event):void
 {
 this.nativeWindow.removeEventListener(Event.CLOSING, handleAppHide);

for (var i:int = NativeApplication.nativeApplication.openedWindows.length - 1; i >= 0; --i) {
 NativeWindow(NativeApplication.nativeApplication.openedWindows[i]).close();
 }
 this.close();
 }
