java - ZK 从组合框中获取选定的项目

Question

我试图在组合框中获取选定的值，但它作为 ComboItem 返回。如何获取字符串形式的值？

<zscript>
  <![CDATA[
    String[] months = { "Ada", "Basic", "C", "C++", "Cobol", "Forth",
            "Fortran", "Go", "Groovy", "Haskell", "Java", "JavaScript", "Lisp",
            "Python", "Ruby", "Scala", "Scheme" };
  ListModel lmonths = new SimpleListModel(months);
]]></zscript>
                    <combobox id="searchCombo"
                        forward="onChange=onSearch" model="@{months}" >
<!-- 
                        <comboitem self="@{each='months'}"
                            label="@{months}" value="@{months}">
                        </comboitem>
 -->

                        </combobox>

这是我的 onSearch 方法

public void onSearch(ForwardEvent event) {


        System.out.println(searchCombo.getSelectedItem());


    prodevt.search(searchCombo.getSelectedItem().toString());
        filterCbox.setChecked(true);



        AnnotateDataBinder binder = (AnnotateDataBinder) win.getVariable(
                "binder", true);

        binder.loadAll();

    }

我是这样解决的

searchCombo.getSelectedItem().getValue().toString();
