public class Viewport
extends SimpleContainer

A LayoutContainer that fills the browser window and monitors window resizing. Viewports are best used for applications that will fill the browser without window scrolling. Children of the viewport can allow scrolling.

Example

  public void onModuleLoad() {
    Viewport viewport = new Viewport();
    viewport.setWidget(new ContentPanel(), new MarginData(10));
    RootPanel.get().add(viewport);
  }
 

The viewport is not added to the root panel automatically. Is is not necessary to call ResizeContainer.forceLayout() after adding the viewport to the RootPanel. Layout will be called after being added to the root panel.
