From the layout sample that is provided, is it possible to keep a window's height and width set at a 100% so that when the browser is resized, the window will maintain the aspect ratio?

For example if you look at this : http://www.extjs.com/deploy/dev/exam...t/complex.html you will notice how the window will automatically resize to the browser's width and height. I cannot find a way to do this with Coolite extender control, eg(ext:window control). Maybe I'm missing something.

Thanks for any help you could provide.
