我无法以编程方式设置组合框的值,有人能告诉我代码中缺少什么吗

 public class Profile extends Window implements AfterCompose {

    @Override
    public void afterCompose() {
       Session session = Sessions.getCurrent(false);
                ApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(
                (ServletContext) getDesktop().getWebApp().getNativeContext());

        UsersDao usersDao = (UsersDao) ctx.getBean("daoUsers");


        User user = (User) session.getAttribute("user");
        user = usersDao.getUser(user.getUsername(),user.getPassword());

        Textbox username_t = (Textbox) this.getFellow("username");
        Textbox password_t = (Textbox) this.getFellow("password");
        Textbox conpassword_t = (Textbox) this.getFellow("con_password");
        Textbox firstname_t = (Textbox) this.getFellow("firstName");
        Textbox lastname_t = (Textbox) this.getFellow("lastName");
        Textbox email_t = (Textbox) this.getFellow("email");
        Combobox hintQuestion_t = (Combobox) this.getFellow("hintQuestion");
        Textbox hintAnswer_t = (Textbox) this.getFellow("hintAnswer");
        Combobox locale_t = (Combobox) this.getFellow("locale");
        Combobox authority_t = (Combobox) this.getFellow("authority");

        username_t.setText(user.getUsername());
        firstname_t.setText(user.getUserDetails().getFirstName());
        lastname_t.setText(user.getUserDetails().getLastName());
        email_t.setText(user.getUserDetails().getEmail());
        Comboitem selectedItem = getSelectedIndexComboboxItem(hintQuestion_t, user.getHintQuestion());
        hintQuestion_t.setSelectedItem(selectedItem);
        hintAnswer_t.setText(user.getHintAnswer());
        selectedItem = getSelectedIndexComboboxItem(locale_t, user.getUserDetails().getLocale());
        locale_t.setSelectedItem(selectedItem);
        selectedItem = getSelectedIndexComboboxItem(authority_t, ((Authority)user.getAuthorities().toArray()[0]).getRole());
        authority_t.setSelectedItem(selectedItem);


    }

   private Comboitem getSelectedIndexComboboxItem(Combobox combobox, String value) {
        List<Comboitem> items = combobox.getItems();
        Comboitem item = items.get(0);
        for (int i = 0; i < items.size(); i++) {
            Comboitem comboitem = items.get(i);
            String label = (String)comboitem.getLabel();
            String cval = (String)comboitem.getValue();
            if ((label!=null && label.equalsIgnoreCase(value)) || (cval != null  && cval.equalsIgnoreCase(value))) {
                item = comboitem;
                break;
            }
        }
        return item;
    }
}

“getSelectedIndexComboboxItem()”确实返回了正确的选定项,但似乎对 UI 没有影响。例如,语言环境设置为默认保加利亚语,我需要将其设置为英语。

我认为这是您的 ZK 版本中的错误。您可以尝试使用 setSelectedItemApi 或 setSelectedItemIndex 而不是 setSelectedItem。

另一方面,即使它有效,您的解决方案也不正确。组合框允许输入与预定义列表中不同的值。组合框唯一真正的结果是文本标签。我认为有一个单独的组合项的“价值”不是一个好主意。
在 Combobox 上使用 setText(),或者如果要将选项限制为预定义列表,请使用 Listbox。

仅查看您的代码,除了 Miklos 指出的内容之外,我还发现了一些错误。

您正在使用基于 Java 的作曲家的 getfellow。但是,您不应该这样做,因为 ZK 会为您自动装配组件。您需要使用 MVC 模式并扩展 GenericForwardComposer。这是一个例子:

ZUL 文件

<window title="composer5 example" border="normal" width="300px" apply="example.MyComposer">
    <grid>
        <rows>
            <row>First Name: <textbox id="firstName"/></row><!-- forward is removed -->
            <row>Last Name: <textbox id="lastName"/></row><!-- forward is removed -->
            <row>Full Name: <label id="fullName"/></row>
        </rows>
    </grid>
</window>

Java 文件

package example;

public class MyComposer extends GenericForwardComposer {
    private Textbox firstName;
    private Textbox lastName;
    private Label fullName;

    @Override
    public void doAfterCompose(Component comp) throws Exception {
        // TODO Auto-generated method stub
        super.doAfterCompose(comp);
    }

    //onChange event from firstName component
    public void onChange$firstName(Event event) { 
        fullName.setValue(firstName.getValue()+" "+lastName.getValue());
    }

    //onChange event from lastName component
    public void onChange$lastName(Event event) {
        fullName.setValue(firstName.getValue()+" "+lastName.getValue());
    }
}

有关更多信息,您可以查阅文档

有了检索所选项目的功能,为什么不使用 Combobox 的getSelectedItem呢?即使您像 Miklos 建议的那样使用 Listbox,您也可以使用相同的功能。

关于设置选中项,您需要将您的 ZK 版本升级到最新。我这样做没有问题。
