ZK listbox 两种分页使用及比较

参考：http://tsinglongwu.iteye.com/blog/849923

以下代码模拟数据量大时情况，采用“<paging>”组件方式

前台Listbox.zul ：

<?page title="Listbox使用" contentType="text/html;charset=UTF-8"?>
<zk xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns="http://www.zkoss.org/2005/zul" 
        xsi:schemaLocation="http://www.zkoss.org/2005/zul http://www.zkoss.org/2005/zul">
<window id="listboxWin" border="normal" apply="test.ListboxCtrl">
<listbox id="listbox">
<listhead sizable="true" >
<listheader id="nameListHeader" label="姓名" align="center"/>
</listhead>
</listbox>
<paging id="pagetest" pageSize="10" totalSize="50000" detailed="true"/>
</window>
</zk>

ListboxCtrl.java :

package test;

import java.util.ArrayList;
import java.util.List;

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.event.EventListener;
import org.zkoss.zk.ui.util.GenericForwardComposer;
import org.zkoss.zul.Label;
import org.zkoss.zul.ListModelList;

import org.zkoss.zul.Listcell;
import org.zkoss.zul.Listitem;
import org.zkoss.zul.ListitemRenderer;

import org.zkoss.zul.event.PagingEvent;

public class ListboxCtrl extends GenericForwardComposer<Component>{

private static final long serialVersionUID = 1L;

private Listbox listbox;
private ListModelList<String> model;
private List<String> testList = new ArrayList<String>();
private Paging pagetest;
private int count = 1;

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

//填充第一页数据
for (int i = 1; i < pagetest.getPageSize()+1; i++) {
            testList.add(i+"");
        }

        model = new ListModelList<String>(testList);
        listbox.setModel(model);
        listbox.setItemRenderer(new testItemRenderer());

//监听分页改变事件
        pagetest.addEventListener("onPaging", new EventListener<Event>() {

            @Override
public void onEvent(Event event) throws Exception {
// TODO Auto-generated method stub
                PagingEvent pe = (PagingEvent) event;

                redraw(pe.getActivePage()+1,pagetest.getPageSize());
            }
        });
    }

public class testItemRenderer implements ListitemRenderer<String>{

        @Override
public void render(Listitem item, String data, final int index)
throws Exception {
// TODO Auto-generated method stub
            
            item.setValue(data);
            Listcell listcell2 = new Listcell();
            Label label = new Label(data);
            listcell2.appendChild(label);
            listcell2.setParent(item);
        }
    }

private void redraw(int activePage,int pageSize) {  

//清空所有数据
        listbox.getItems().clear();  
        testList.clear();

int total = activePage * pageSize;

for (int i = total-pageSize+1; i <= total; i++) {

//当超过总页数时
if (i > pagetest.getTotalSize()) {
break;
            }

            testList.add(i+"");
        }

        model = new ListModelList<String>(testList);
        listbox.setModel(model);
    } 
}

效果：
