ZK ListBox Two types of paging usage and comparison

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

The following code simulates a large amount of data, using the "<paging>" component approach

Front desk Listbox.zul:

<?page title= "listbox using" contenttype= "Text/html;charset=utf-8"?><ZKXmlns: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"><windowID= "Listboxwin"Border= "normal"Apply= "Test.
