I was actually surprised that something like this hasn’t come in the sdk with AIR 1.0 release. I built this during the AIR beta and adjusted it now to run on 1.0. It acts as a global window manager and manages all your window instances in an Air application.

It uses SimpleWindow class which extends mx.core.Window and adds some needed functionalities.

For the ones interested in the ways things work here’s an image which speaks better english.

A short example of how it should be used.
First, create a window component extending SimpleWindow. Let’s say MyWindow.mxml:

<?xml version="1.0" encoding="utf-8"?>
<core:Simplewindow>
      xmlns:core="com.flexwizz.core.*"
      xmlns:mx="http://www.adobe.com/2006/mxml"
      width="400" height="300"
      title="My Window">
      <mx:Text width="100%" text="I am MyWindow">
      </mx:Text>
</core:Simplewindow>

Then you can simply use WindowManager.openWindow(MyWindow) . Simple enough…

I often needed to restrict more then 1 windows of a specific type to be opened at once. And you can achieve that pretty simple here by specifying the windowUID on that component above. The property windowUID should always be set on component declaration, must be a const (binding isn’t made here) and before opening it with WindowManager. Example (MyWindow.mxml):

MXML:

<?xml version="1.0" encoding="utf-8"?>
<core:Simplewindow>
      xmlns:core="com.flexwizz.core.*"
      xmlns:mx="http://www.adobe.com/2006/mxml"
      width="400" height="300"
      title="My Window"
      windowUID="com.wins::MyWindow">
      <mx:Text width="100%" text="I am MyWindow">
      </mx:Text>
</core:Simplewindow>

And open it:

WindowManager.openWindow(MyWindow)

When you try to open a 2nd window with the same windowUID, WindowManager will activate the window that is already opened with that windowUID. Or you can specify it to notify that the window is already opened which can be done using the 3rd argument of the openWindow methods.

You can use any string on windowUID property and the WindowManager will never open 2 instances with the same windowUID. But actually, the way I thought it, if you want to easily keep track of your windows in the application you can set this property to package+”::”+ClassName string as I did above in the MyWindow component. This way you can easily use getQualifiedClassName(ClassName) to get the windowUID of that. For example for MyWindow.mxml:

WindowManager.getOpenedWindow(getQualifiedClassName(MyWindow); // returns the window's instance

Anyways, there is a example application + source-code which explains all the functionalities better.

You can get the recommended Example Application - Air file included, the Lib SWC, Lib Source and AsDocs.

Btw, you should also check the code license page.

Hope this helps! and let me know if it’s useful or if you run into trouble, find bugs, etc.
