Primefaces:如何创建< p:menubar>动态地在primefaces 4中? [英] Primefaces : how to create <p:menubar> dynamically in primefaces 4?

问题描述

我正在从素面3.4迁移到素面4.我在素面3.4中创建了动态菜单栏，没有任何问题. 这是豆子:

i'm migrating from primefaces 3.4 to primfaces 4.I had the menubar created dinamically in primefaces 3.4 with no probleme. here is the bean:

public MenuBean() {
    MenuItem menuItem = new MenuItem();
    Submenu submenu = new Submenu();


    submenu.setLabel("Nos Solutions");
    menuItem.setValue("Computers");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    menuItem = new MenuItem();
    menuItem.setValue("Clothes");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    simpleMenuModel.addSubmenu(submenu);

    submenu = new Submenu();
    submenu.setLabel("Nos Problemes");
    menuItem.setValue("Computers");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    menuItem = new MenuItem();
    menuItem.setValue("Clothes");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    simpleMenuModel.addSubmenu(submenu);

    submenu = new Submenu();
    submenu.setLabel("Nos Solutions");
    menuItem.setValue("Computers");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    menuItem = new MenuItem();
    menuItem.setValue("Clothes");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    simpleMenuModel.addSubmenu(submenu);

    submenu = new Submenu();
    submenu.setLabel("Nos Solutions");
    menuItem.setValue("Computers");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    Submenu submenu1 = new Submenu();
    submenu1.setLabel("Offres");
    menuItem = new MenuItem();
    menuItem.setValue("Stage Etudiants");
    menuItem.setUrl("#");
    submenu1.getChildren().add(menuItem);
    menuItem = new MenuItem();
    menuItem.setValue("Jeunes diplomés");
    menuItem.setUrl("#");
    submenu1.getChildren().add(menuItem);

    submenu.getChildren().add(submenu1);
    menuItem = new MenuItem();
    menuItem.setValue("Clothes");
    menuItem.setUrl("#");
    submenu.getChildren().add(menuItem);

    simpleMenuModel.addSubmenu(submenu);
    menuItem = new MenuItem();
    menuItem.setValue("Clothe");
    menuItem.setUrl("#");
    simpleMenuModel.addMenuItem(menuItem);

}

public MenuModel getSimpleMenuModel() {
    return simpleMenuModel;
}

此处是xhtml: <p:menubar model="#{menuBean.simpleMenuModel}"/>

here the xhtml: <p:menubar model="#{menuBean.simpleMenuModel}"/>

现在在primefaces 4中，类/接口似乎已更改，而我不知道在此版本中会这样做. 谁能帮忙！！！

now in primefaces 4 the classes/interfaces seems to be changed, and i don't know to do it in this version. can anyone help please !!!.

推荐答案

请查看页面:

PrimeFaces-新的菜单模型.

简单的例子:

MenuModel model = new DefaultMenuModel();

DefaultSubMenu subMenu = new DefaultSubMenu("some submenu");
DefaultMenuItem menuItem = new DefaultMenuItem("some item");
subMenu.addElement(menuItem);

model.addElement(subMenu);

model.generateUniqueIds();

方法generateUniqueIds()将使您免于自己创建和设置ID字符串.

Method generateUniqueIds() will spare you from creating and setting id strings yourself.
