SmartGwt 下拉列表
下列代码实现的是 一个下拉列表的功能：
?
package com.tservice.PGA.smApp.client.Meeting;import com.google.gwt.core.client.GWT;import com.google.gwt.user.client.rpc.AsyncCallback;import com.google.gwt.user.client.rpc.ServiceDefTarget;import com.smartgwt.client.data.fields.DataSourceEnumField;import com.smartgwt.client.data.fields.DataSourceTextField;import com.smartgwt.client.widgets.form.fields.SelectItem;import com.tservice.PGA.smApp.client.service.SmService;import com.tservice.PGA.smApp.client.service.SmServiceAsync;public class publicUserStringArrayList {SmServiceAsync mainService = (SmServiceAsync) GWT.create(SmService.class);ServiceDefTarget endpoint = (ServiceDefTarget) mainService;String moduleBaseURL = GWT.getModuleBaseURL()+"rpc";DataSourceTextField peopleText=null;SelectItem select=null;public publicUserStringArrayList(String titleId,String name){endpoint.setServiceEntryPoint(moduleBaseURL);//"people","参与者" peopleText=new DataSourceTextField(titleId,name,10); select=new SelectItem(titleId,name);mainService.getUserLists(new AsyncCallback(){public void onFailure(Throwable caught) {}public void onSuccess(Object result) {String[] str=(String[])result;select.setValueMap(str);}});}}??
其他前端页面调用：
?
final publicUserStringArrayList userList=new publicUserStringArrayList("people","参与者");?
DynamicForm form=new DynamicForm();form.setUseAllDataSourceFields(true);//只有这样才能让DataSource控件与常规控件（SelectItem）同事显示 form.setDataSource(dataSource);form.setFields(userList.select);
?
DataSource dataSource=new DataSource();dataSource.setClientOnly(true);?
