Center Adobe AIR Window

I always end up digging around in past projects for this snippet, so I’m putting it here for safe keeping, and maybe it’ll help you out too.

public static function centerWindow(win:WindowedApplication):void
   var screenBounds:Rectangle = Screen.mainScreen.bounds;
   win.nativeWindow.x = Math.floor((screenBounds.width - win.width)/2);
   win.nativeWindow.y = Math.floor((screenBounds.height - win.height)/2);

The real trick here is that you have to call this on creationComplete instead of one of the other events that seems like it might work like applicationComplete. A callLater() couldn’t hurt either. ;)
