RootLayoutPanel is a container that takes up all the visible area and always resizes to cover the whole viewport. Other than that, it's a LayoutPanel, so it wraps all its children within a div to be able to accurately manage their position and size in all supported browsers. And it creates an additional, hidden, div (two in the case of IE6) as a way to measure EMs and EXs in pixels. So, yes, those divs are necessary. But RootLayoutPanel and RootPanel are not interchangeable, they have distinct purposes. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
