Vaadin 15 Open URL ?

I would like to open a URL within a dialog, is it possible? … in version 8, I used the BrowserFrame, but I can’t get it in 15 …
Could someone help me please

This seems to work:

Dialog dialog = new Dialog();
dialog.add(new IFrame("http://www.gwtproject.org/"));
dialog.open();

Thanks, it worked = D
