本文主要是介绍wicket 中ListView和WebMarkupContainer以及AjaxButton的使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
此例子为wicket中在页面中点检索后，在本页面显示出检索结果所用到的控件：import java.util.ArrayList;
import java.util.List;
import jp.co.infomart.foods.common.admin.page.BasePage;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.form.AjaxButton;

import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.list.ListItem;
import org.apache.wicket.markup.html.list.ListView;
/**

public class Test_ListView extends BasePage {
private Form form;
private static List books = new ArrayList();
WebMarkupContainer container;
public Test_ListView(){
super();
form = new Form("myForm");
this.add(form);
container = new WebMarkupContainer("listViewContainer");
container.setOutputMarkupId(true);
//
ListView listView = new ListView("books",books){
@Override
protected void populateItem(ListItem item) {
Test_ListViewModel book = (Test_ListViewModel)item.getModelObject();
item.add(new Label("id",Integer.toString(book.getId())));
item.add(new Label("title",book.getTitle()));
item.add(new Label("author",book.getAuthor()));
}
};
container.add(listView);
form.add(container);
AjaxButton ajaxButton = new AjaxButton("ajaxButton") {
@Override
protected void onSubmit(AjaxRequestTarget art, Form<?> form) {
init();
art.addComponent(container);
}
@Override
protected void onError(AjaxRequestTarget art, Form<?> form) {
throw new UnsupportedOperationException("Not supported yet.");
}
};
form.add(ajaxButton);
}
public void init(){

for(int i=1;i<10;i++){
Test_ListViewModel book = new Test_ListViewModel();
book.setId(i);
book.setAuthor("author"+i);
book.setTitle("title"+i);
books.add(book);
}
}
}
