Menu calling classes, or view

General

Hello good afternoon!

Dear today with the help of examples
http://demo.vaadin.com/book-examples-vaadin7/book/
build the menu, most unfortunately what the swing is quiet in vaadin’m picking up ugly, met along the way such a navigator and could not make it work then peopl who can assess what I did (better what I copied) and where I am going wrong .

Note. The menu is being rendered can not call the classes linked to the menu, does not give any error, do not simply nothing.

@Override
    protected void init(VaadinRequest request) {
        setLocale(new Locale("pt", "BR"));
        VerticalLayout layout = new VerticalLayout();
        layout.setSizeFull();
        setContent(layout);
        
        // Mostrar uma view controlada pelo navigator
        Panel viewDisplay = new Panel();
        viewDisplay.setSizeFull();
        // Criar um navigator
        Navigator navigator = new Navigator(this, viewDisplay);
        //navigator.addView("beverages", new MyView("Beverages View"));
        //navigator.addView("snacks",    new MyView("Snacks View"));
        //navigator.addView("Serviços",  new MyView("Services View"));
        navigator.addView("Beverages", new Beverages()  ); 
        navigator.addView("Snacks", new Snacks()  ); 
        navigator.navigateTo("Beverages");
        
        NavigableMenuBar menu = new NavigableMenuBar(navigator);
        menu.addStyleName("mybarmenu");
        layout.addComponent(menu);
        
        layout.addComponent(viewDisplay);
        layout.setExpandRatio(viewDisplay, 1.0f);
        
        navigator.addViewChangeListener(menu);
        
        menu.addView("Beverages", "Beverages", null);
        menu.addView("Snacks", "Snacks", null);
        
        
        //updateContent();
    }

menu.addView("Beverages", "Beverages", null); menu.addView("Snacks", "Snacks", null) instead of null (third parameter) pass an instance of Menu.Command class.

Hello Good morning!

Vikrant Thanks for the feedback. I will proceed as recommended and put the return.

Olá bom dia!

Vikrant Obrigado pelo retorno. Vou proceder como recomendado e posto o retorno.

Hi!

I did not see how to proceed because the third parameter is an icon, menu is a NavigableMenuBar object

the example
http://demo.vaadin.com/book-examples-vaadin7/book/#component.menubar.navigator

class NavigableMenuBar extends MenuBar implements ViewChangeListener {
   
    HashMap<String,MenuItem> menuItems = new HashMap<String,MenuItem>();
    
    private Navigator navigator = null;
    
    public NavigableMenuBar(Navigator navigator) {
        this.navigator = navigator;
    }
    
    MenuBar.Command mycommand = new MenuBar.Command() {

        @Override
        public void menuSelected(MenuItem selectedItem) {
            String viewName = selectItem(selectedItem);
            navigator.navigateTo(viewName);                                
        }    
    };
    
    public void addView(String viewName, String caption, Resource icon) {
        menuItems.put(viewName, addItem(caption, icon, mycommand));
    }

Probably you could allow remote access to your computer, so that I could look into your code.

You forgot to add the components in the Layout / View which is the Snacks and Beverages.

Você esqueceu de adicionar os componentes no Layout/View que é o Snacks e Beverages.

Snacks.java:51 && Beverages.java:51

        setSizeFull();
        [b]
addComponent(viewLayout);
[/b]

Hello!

Dear Pedro okay? so I was thinking it would not receive another return, the error that is lacking I insert these two classes this information you provided, I will do as suggested and post the application behavior.

Hi Pedro!

It worked! Was 15 days with the problem and now worked and all because of a little more accurate your comment.

Well I confess that my Java is not there these things, but now I can go ahead and try to do some screens since the menu is running.

Thank you so much.
