Scripting the AIR HTML Container
2 Override methods of the new class to handle changes in the user interface-related settings. For example, the
following class, CustomHost, defines behaviors for calls to window.open() and changes to

window.

import flash.html.*;
import flash.display.StageScaleMode;

}
public class CustomHost extends HTMLHost
{
import flash.html.*;

createWindow(windowCreateOptions:HTMLWindowCreateOptions):HTMLLoader
{
var initOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
var bounds:Rectangle = new Rectangle(windowCreateOptions.x,
windowCreateOptions.y,
windowCreateOptions.width,
windowCreateOptions.height);
var htmlControl:HTMLLoader = HTMLLoader.createRootWindow(true, initOptions,
windowCreateOptions.scrollBarsVisible, bounds);
htmlControl.htmlHost = new HTMLHostImplementation();
if(windowCreateOptions.fullscreen){
htmlControl.stage.displayState =
StageDisplayState.FULL_SCREEN_INTERACTIVE;
}
return htmlControl;
}
override public function updateTitle(title:String):void
{
htmlLoader.stage.nativeWindow.title = title;
}
}

the new class. Assign the new object to the htmlHost property of the HTMLLoader. The following Flex code uses
the CustomHost class defined in the previous step:
