GWT使用DOM.clone克隆小部件

Question

我希望以編程方式克隆小部件。我能夠用Dom.clone克隆Widget中的Element，但我似乎無法從此克隆的元素中創建Widget。這可能嗎？

 //somewhere in onModuleLoad()...   
    Button button = new Button("Original"); 
    RootPanel.get().add(button); 

    //.....later on... 
    Element buttonCloneElement = DOM.clone(button.getElement(), true); 
    Widget buttonClone; 

    buttonClone = new Button(buttonCloneElement); //FAIL - No such constructor 
    buttonClone.setElement(buttonCloneElement); //FAIL - No such setter method 

    //This may work but looks messy to me 
    buttonClone.getElement().setInnerHTML(button.getElement().getInnerHTML()); 

    //add the clone to the root panel?? 
    RootPanel.get().add(buttonClone); 

有沒有克隆Widget的另一種方法？

buttonClone = Button.wrap(buttonCloneElement)
