如何在Uibinder .ui.xml模板中添加项目到GWT ListBox？

如何使用UiBinder添加列表框项？

这是枚举的翻译列表框，我想这也适用于具有字符串值的列表框(GWT版本：2.1.0)

您只需要渲染器来翻译枚举值。

// UI XML

<g:ValueListBox ui:field="requesterType"/>

// JAVA CODE

@UiField(provided = true)
 ValueListBox<RequesterType> requesterType = new ValueListBox<RequesterType>(requesterTypeRenderer);

 static EnumRenderer<RequesterType> requesterTypeRenderer = new EnumRenderer<RequesterType>();

 public Constructor() {
     requesterTypeRenderer.setEmptyValue(Translations.translateEmptyValue(RequesterType.class));
     requesterType.setAcceptableValues(Arrays.asList(EnumUtil.getRequesterTypes()));
 }

/**
  * Translates enum entries. Use setEmptyValue() if you want to have a custom empty value. Default empty value is "".
  * 
  * @param <T>
  *            an enumeration entry which is to be registered in {@link Translations}
  */

public class EnumRenderer<T extends Enum<?>> extends AbstractRenderer<T> {

   private String emptyValue = "";

   @Override
   public String render(T object) {
       if (object == null)
           return emptyValue;
       return Translations.translate(object);
   }

   public void setEmptyValue(String emptyValue) {
       this.emptyValue = emptyValue;
   }

}
