MenuBar Error

[Rubén V]

Hi

I am trying to make use of a traditional menu that appears at the bottom of the form (not lateral or contextual).

The error that appears to me is:

java.lang.ClassCastException: com.mycia.menubar.MenuBar cannot be cast to com.codename1.ui.MenuBar

I appreciate if you provide me with an example to continue moving forward in my project.

My code:

public class MenuBar {

    private Form current;

    public void init(Object context) {

        try {

            // use two network threads instead of one

            updateNetworkThreadCount(2);

            Resources theme = Resources.openLayered("/theme");

            UIManager.getInstance().setThemeProps(theme.getTheme(theme.getThemeResourceNames()[0]));

            UIManager.getInstance().getLookAndFeel().setMenuBarClass(MenuBar.class);

        } catch (IOException ex) {

        }

    }

    public void start() {

        if (current != null) {

            current.show();

            return;

        }

        Image imSelect = null;

        Image imCancel = null;

        Image imMenu = null;

        try {

            imSelect = Image.createImage("/m_brasilia.png");

            imCancel = Image.createImage("/m_brasilia.png");

            imMenu = Image.createImage("/m_brasilia.png");

        } catch (IOException ex) {

        }

        //

        Form menuBar = new Form("Menu Prueba");

        menuBar.addCommand(new Command("Command 1", imSelect));

        menuBar.addCommand(new Command("Command 2", imCancel));

        menuBar.addCommand(new Command("Command 3", imMenu));

        menuBar.addCommandListener(new ActionListener() {

            public void actionPerformed(ActionEvent evt) {

                Dialog.show("WARNING !", ((Command) evt.getSource()).getCommandName() + " pressed !", "OK", null);

            }

        });

        menuBar.show();

    }

    public void stop() {

        current = getCurrentForm();

    }

    public void destroy() {

    }

}

Hi,

what's the stack of the error?

I wouldn't call a class "MenuBar" as we have a public Codename One class with that exact name and imports might be problematic here...

I also wouldn't use commands for that. Most of the menus with the buttons in the bottom are really just tabs so for 90% of the cases you should just use tabs.

For the rest I would use a border layout form and place buttons in the south area to create these options.
