What is the proper method to Embed a Java Applet in an EXT-Gwt Container?

I'm using Sencha EXT-Gwt and trying to embed a Java Applet in a ContentPanel. I want the container to fill the whole screen (adding it to the rootpanel), and then i want the applet to be 100% width and height of the available space, minus whatever border, header, footer, etc I put in the Surrounding Ext widget.

When I try to do this intuitively, it results in the size of my applet overrunni开发者_开发知识库ng the bottom of the container (i.e, the applet ends up bigger than the available space. How do i get it to "stay" in it's available space?

    ContentPanel cp = new ContentPanel();
    cp.setHeading("Folder Contents");
    cp.setHeaderVisible(false);
    cp.setCollapsible(false);
    cp.setFrame(false);
    cp.setBottomComponent(toolBar);

    RootPanel.get().add(cp);

    cp.layout();
    cp.add(widgetAppletOne);
    cp.layout();

Thanks,

Turns out I had to use a FitLayout in a Viewport to achieve the full-browser window effect I wanted.

    ContentPanel cp = new ContentPanel();
    cp.setHeading("Folder Contents");
    cp.setHeaderVisible(false);
    cp.setCollapsible(false);
    cp.setFrame(false);
    cp.setBottomComponent(toolBar);
    cp.add(widgetAppletOne);
    cp.setLayout(new FitLayout());  

    Viewport v = new Viewport();  
    v.setLayout(new FitLayout());  
    v.add(cp);

    RootPanel.get().add(v);

    v.layout();
    cp.layout();
