Detecting various output options in an AIR application on Mac
I have an AIR application running on a Mac and I want the behavior to hide the window when someone "closes" the application (for example, hits a red "x" or cmd-w button). However, if someone hits cmd-q or selects "Quit" from the dock context menu or top level menu, I want the application to actually close.
I can prevent Default for the "close" event dispatched by the application, however this causes all "closed" methods to simply hide the window. The only way to close the app at this point is by ForceQuit (or through a separate interface I provide, such as the context menu option on the dock icon).
I also tried to capture the cmd-q keyDown event manually, but it is not dispatched. Also, it won't help if people try to log out of the app using menu options.
Also, if I prevent the Default method on the close method, it causes my application to immediately cancel the closing process (which is a terrible user experience).
Is there a way to detect the different methods for closing an AIR application? I want to be able to distinguish between these closing methods and react accordingly.

Try this to close, from what I understand there was / is a bug in the framework so that if you enable AIR update it breaks support for cmd-q, with this thread being used here: http: //www.adobe. com / cfusion / webforums / forum / messageview.cfm? forumid = 72 & catid = 670 & threadid = 1373568
This may or may not be applicable to your situation.
NativeApplication.nativeApplication.addEventListener(Event.EXITING,
function(e:Event):void {
var opened:Array = NativeApplication.nativeApplication.openedWindows;
for (var i:int = 0; i < opened.length; i ++) {
opened[i].close();
}
});

Try this, I'm sure there must be a better way to handle this, but it worked for me.
