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();
}
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();
}

Using AIR 1.5.1 InovkeReason for friendlier applications
I recently discovered a new feature of AIR 1.5.1 that makes AIR applications more consumer friendly in certain situations. When you have your application set to start on user login using “NativeApplication.nativeApplication.startAtLogin = true”, you may want the application to start as a background process rather than show the entire application at login. In AIR 1.5.1 there is a new property of the InvokeEvent called “reason” that will report if the application was started at login or was started when the users invokes the application by launching the application.
By capturing this event and testing for InovokeReason.LOGIN, you can keep your application invisible and only show the windows docked in the system tray. If a users starts the application it will be InvokeReason.STANDARD and you can then show the application as normal. I find it annoying to have a ton of windows popping up on my screen when I restart my computer.
I usually set up an InvokeEvent when a users clicks on the system tray icon to activate the application and bring it to the forefront. I initially set WindowsApplicatoin visible=”false” so the application is invisible on start. If the the InvokeEventReason is “LOGIN”, I keep the application invisible, in other cases I activate the application and bring it to the forefront.
It should be noted that the InvokeEvent fires on application start up as well as from running the the application from the IDE (so you can’t test it fully unless you install the application and login again). Also, because of timing of events at start up, the application is invisible even when you set it to active, so it will blink if the InvokeEventReason is STANDARD. To avoid this behavior, I use the “windowComplete” event of the WindowedApplication to add the InvokeEvent listeners. So the code might look something like the following:
