AIR : How to create air app which does not appear in taskbar

There are a couple of needs in Flex users group in Japan, So I test it.

The important thing is to use "mx:Application" instead of "mx:WindowedApplication".

Cautions :
WinTest2.mxml appears in taskbar because it uses binding for type property. When you use mxml class based on mx.core.Window, you should write it directly (see WinTest5.mxml).

You can download sources from here.
WinTest.zip

WinTest.mxml ( Main app )
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"> <mx:Script> <![CDATA[ import mx.core.Window; private function init():void { createWindow("WinTest1-1"); createWindow("WinTest1-2"); var win2:WinTest2 = new WinTest2(); win2.open(true); var win3:WinTest3 = new WinTest3(); win3.open(true); var win4:WinTest4 = new WinTest4(); win4.open(true); var win5:WinTest5 = new WinTest5(); win5.open(true); createWindow("WinTest1-3"); } private function createWindow(title:String):void { var win:Window = new Window(); win.systemChrome = NativeWindowSystemChrome.NONE; win.type = NativeWindowType.LIGHTWEIGHT; win.transparent = true; win.title = title; win.open(true); } ]]> </mx:Script> </mx:Application>

WinTest2.mxml
<?xml version="1.0" encoding="utf-8"?> <mx:Window xmlns:mx="http://www.adobe.com/2006/mxml" systemChrome="none" type="{NativeWindowType.LIGHTWEIGHT}" transparent="true" title="WinTest2"> </mx:Window>

WinTest3.as
package { import flash.display.NativeWindowSystemChrome; import flash.display.NativeWindowType; import mx.core.Window; public class WinTest3 extends Window { public function WinTest3() { super(); type = NativeWindowType.LIGHTWEIGHT; systemChrome = NativeWindowSystemChrome.NONE; transparent = true; title = "WinTest3"; } } }

WinTest4.mxml
<?xml version="1.0" encoding="utf-8"?> <WinTest3 xmlns="*" xmlns:mx="http://www.adobe.com/2006/mxml" title="WinTest4"> </WinTest3>

WinTest5.mxml
<?xml version="1.0" encoding="utf-8"?> <mx:Window xmlns:mx="http://www.adobe.com/2006/mxml" systemChrome="none" type="lightweight" transparent="true" title="WinTest5"> </mx:Window>
