java - 我的 zkoss 代码出了什么问题？

Question

 <listbox id="lbx" rows="4">
   <listhead><listheader label="Name"></listheader><listheader label="Album"></listheader></listhead>
  </listbox>
public class page extends GenericForwardComposer{
    Combobox searchBox;
    private Grid SuggestGrid;

    private String q;
     Button b;
    Page p;
    Label la; Listcell h,m;
    protected Listbox lbx; // autowired

    private ListModelList list,listq; // the model of the listbox
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);


        for(int i=0;i<=10;i++)
        {
            Listitem li = new Listitem();
            new Listcell("example").setParent(li);
            new Listcell("google").setParent(li);

           Label subTotalLb = new Label("$example ");
           subTotalLb.setParent(li);
            li.setParent(lbx);
        }


    }

我只能在此列表单元格中添加字符串。

为什么我不能在此添加按钮或标签......

您可以在Listcell中创建自己的按钮

public void doAfterCompose(Component comp) throws Exception {
    super.doAfterCompose(comp);

    for(int i=0;i<=10;i++){
        Listitem li = new Listitem();
        Listcell lic = new ListCell();
        li.appendChild(lic);
        Button myBtn = new Button("Btn");
        myBtn.setParent(lic);

        //...

    }
}
