Primefaces : how to create dynamically in primefaces 4?

问题

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;
}

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

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 !!!.

回答1:

Please, have a look at the page:

PrimeFaces - New MenuModel.

Simple example:

MenuModel model = new DefaultMenuModel();

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

model.addElement(subMenu);

model.generateUniqueIds();

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

Personally i create my menu dynamically like this on primeface 4.0 :

Bean:

private MenuModel menumodel = new DefaultMenuModel();

//create the first menu item
DefaultMenuItem accueil = new DefaultMenuItem("Accueil");
accueil.setStyleClass("accueil");
accueil.setUrl("/accueil.jsf");
this.menumodel.addElement(accueil);
//Start here i create submenu with personal access for all user
for (Autorisation auto : this.permList) {
    if (auto.getRessource().getSousMenu() != null) {
        if (auto.getRessource().getSousMenu().size() != 0) {
            //Create submenu
            DefaultSubMenu submenu = new DefaultSubMenu();
            submenu.setIcon(null);
            submenu.setLabel(auto.getRessource().getMenu());
            this.menumodel.addElement(submenu);
            for (Ressource r : auto.getRessource().getSousMenu()) {
                //Feed submenu with menu item
                DefaultMenuItem item = new DefaultMenuItem();
                item.setValue(r.getMenu());
                item.setUrl(r.getPath());
                submenu.addElement(item);
            }
        }
    }
}
