Close a loaded HTML file

Question

Dear Friends,
i have developed a ticker, in that if the user clicks help
button, it will load a HTML file from the site. my file works fine,
wherever user clicks on that button it is creating new native html
file. i can disable my help button when they native HTML browser. i
need to enable my help button when they close the HTML window. i
dont know how to trace the closing of HTML window.
to load HTML iam using the following code:
var initOptions:NativeWindowInitOptions = new
NativeWindowInitOptions();
initOptions.resizable = false;
initOptions.maximizable = false;
initOptions.minimizable = false;
var bounds:Rectangle = new Rectangle(10, 10, 630, 500);
var html2:HTMLLoader = HTMLLoader.createRootWindow(true,
initOptions, true, bounds);
var urlReq2:URLRequest = new URLRequest("
http://www.xyz.com/desktop/help.html");
html2.load(urlReq2);
helpbutton.enable = false;
html2.stage.nativeWindow.activate();
i need to enable my helpbutton, when they close (unload),
this html page..
thanks and Regards,
Syed Abdul Rahim

Answer 1

Add an event listener for the window's close event:
html2.stage.nativeWindow.addEventListener(NativeWindow.CLOSE,
closeFunction);
function closeFunction( event:Event ):void
helpbutton.enable = true;
}
