我沒有使用您使用的特定小部件，但這是一般想法。

public class Index implements EntryPoint { 

    public void onModuleLoad() { 
     // the panel that holds the content widgets 
     final SimplePanel mainPanel = new SimplePanel(); 
     // the panel that holds the links 
     FlowPanel leftPanel = new FlowPanel(); 
     // the first content widget 
     final Label oneContent = new Label("one content"); 
     // the second content widget 
     final Label twoContent = new Label("two content"); 
     // the anchor to load the first content widget when clicked 
     Anchor one = new Anchor("one menu"); 
     // add the click handler to do the content swap 
     one.addClickHandler(new ClickHandler() { 

      @Override 
      public void onClick(ClickEvent event) { 
       // remove any previous content 
       mainPanel.clear(); 
       // add the first content widget 
       mainPanel.add(oneContent); 
      } 
     }); 

     // the anchor to load the first content widget when clicked 
     Anchor two = new Anchor("two menu"); 
     // add the click handler to do the content swap 
     two.addClickHandler(new ClickHandler() { 

      @Override 
      public void onClick(ClickEvent event) { 
       // remove any previous content 
       mainPanel.clear(); 
       // add the second content widget 
       mainPanel.add(twoContent); 
      } 
     }); 

     leftPanel.add(one); 
     leftPanel.add(two); 
     // add everything to the RootPanel 
     RootPanel.get().add(leftPanel); 
     RootPanel.get().add(mainPanel); 
    } 
}
