Calling Application.application.enable from a TitleWindow in a different mxml component

I have a Flex RIA App, and in the application tag there is a button when it's pressed calls upon a TitleWindow from another .mxml file, and sets

application.enable = false

That way the user can't use any of the components in the application, and still can use the components in the TitleWindow.

The problem is when the TitleWindow is closed I want it to restore the application back to

application.enable = true

Which enables the application once again. But I can't call that code from inside the TitleWindow .mxml

How can I do it?

Here is the Source:

Loja.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="585" height="450" xmlns:ns1="com.*">
<mx:Style source="theme/simplicitygray.css" />

    <mx:Script>
        <![CDATA[
            import mx.managers.PopUpManager;
            private var clientid = 0;       
            
            public function openWindow() : void
            {
                if (clientid == 0) 
                {
                    PopUpManager.createPopUp(this,Login,false);
                    application.enabled = false;
                } else {
                    PopUpManager.createPopUp(this,Conta,false);
                    application.enabled = false;
                }
            }
        ]]>
    </mx:Script>
    
    <mx:Panel x="10" y="40" width="565" height="400" layout="absolute">
    </mx:Panel>
    <mx:MenuBar x="10" y="10" width="565" height="22"></mx:MenuBar>
    <mx:Button x="508" y="10" label="Aceder" click="openWindow();"/>
    
</mx:Application>

And one of the title windows. Once they are the same.

Login.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="350" height="200" creationComplete="centerWindow()" showCloseButton="true" close="closeWindow()" title="Login">
    
    <mx:Script>
        <![CDATA[
            import mx.managers.PopUpManager;
            public function centerWindow():void
            {
                PopUpManager.centerPopUp(this);
            }
            
            public function closeWindow():void
            {
                PopUpManager.removePopUp(this);
            
            }
            
       ]]>
       
    </mx:Script>
    
</mx:TitleWindow>

Solution

application is a static property of the Application class and can be called from the TitleWindow

public function closeWindow():void
{
    PopUpManager.removePopUp(this);
    Application.application.enabled = true;
}

BTW, There is another easier way to achieve the following:

That way the user cant use any of the components in the application, and still can use the components in the TitleWindow.

That is to use a modal popup. Set the third parameter of the createPopUp to true and that's it - you don't have to enable/disable the application manually: flex will take care of it.

PopUpManager.createPopUp(this,Login, true);

application will automatically become functional once you call removePopUp.
