How to open real popup window in Flex

I need to open popup window in my flex / air application that will be displayed like normal application window. All I could manage is to open a window which is displayed inside my main flex window.

Is it something like that possible, and is there some workarounds if not?

From stackoverflow

• You'll have to use a NativeWindow for that. More info the API docs: http://livedocs.adobe.com/flex/3/langref/flash/display/NativeWindow.html

  import flash.display.NativeWindowInitOptions;
  import flash.display.NativeWindowSystemChrome;
  import flash.display.NativeWindowType;
  import flash.display.NativeWindow;
  import flash.display.StageAlign;
  import flash.display.StageScaleMode;
  import flash.geom.Rectangle;
  
  var windowOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
  windowOptions.systemChrome = NativeWindowSystemChrome.STANDARD;
  windowOptions.type = NativeWindowType.NORMAL;
  
  var newWindow:NativeWindow = new NativeWindow(windowOptions);
  newWindow.stage.scaleMode = StageScaleMode.NO_SCALE;
  newWindow.stage.align = StageAlign.TOP_LEFT;
  newWindow.bounds = new Rectangle(100, 100, 800, 800);
  
  newWindow.activate();
  

• For a Flex application, you'll want to use mx.core.Window. For a non-Flex ActionScript application, you should use flash.display.NativeWindow.

  Dev er dev : Thanks, mx.core.Window did the trick.

• There is a good example here for flex 3.
