No longer possible to display URL in Window?

In Vaadin 6, one could display external content in a Window like this:

final Window win = new Window();
            final ExternalResource url = new ExternalResource("http://www.google.com");
            win.setContent(url);
            win.open(url);
            win.setWidth("50%");
            win.setHeight("50%");
            ui.addWindow(win);
            win.center();

But in Vaadin 7, the open() method no longer exists.  Is there another way of doing this now, or is this functionality lost?

All help much appreciated

Hi Thomas, I wasn't actually even aware Vaadin 6 had this functionality, but you should be able to do it in Vaadin 7 simply by setting a full-sized BrowserFrame component as the Window's content.

Hi Johannes,
Many thanks!  Yes, the BrowserFrame did the trick.
