How to create Custom Menu in our Application.

How To implement Custom Menu in our Blackberry Application:-

Step1)
Create a class called BaseMainScreenwhich extends MainScreen.
I ll define the custom menu inside this class.

public class BaseMainScreen extends MainScreen {
    Border _menuBorder;
    Background _menuBackground,_caretBackground;
    Font _menuFont;

    protected BaseMainScreen() {
        super(MainScreen.NO_VERTICAL_SCROLL | MainScreen.NO_VERTICAL_SCROLLBAR);
       
        XYEdges thickPadding = new XYEdges(10, 10, 10, 10);
        _menuBorder = BorderFactory.createBitmapBorder(thickPadding,
                Bitmap.getBitmapResource("bb-menu.png"));
        /*Bitmap bitmapImage = Bitmap.getBitmapResource("user_pass_bg.png");
        _menuBackground=BackgroundFactory.createBitmapBackground(bitmapImage);*/
       
    _menuBackground = BackgroundFactory.createSolidBackground(
                Color.DARKGREEN);
        _caretBackground = BackgroundFactory.createSolidBackground(
                Color.LIMEGREEN);
        try {
            FontFamily family = FontFamily.forName("Arial");
            _menuFont = family.getFont(Font.PLAIN, 30, Ui.UNITS_px);
        } catch (final ClassNotFoundException cnfe) {
            UiApplication.getUiApplication().invokeLater(new Runnable() {
                public void run() {
                    Dialog.alert("FontFamily.forName() threw "
                            + cnfe.toString());
                }
            });
        }
    }

    protected void makeMenu(Menu menu, int context) {
        menu.setBorder(_menuBorder);
        menu.setBackground(_menuBackground);
        menu.setFont(_menuFont);
        menu.setCaretBackground(_caretBackground);
        super.makeMenu(menu, context);
    }

}

Step2)
How to use This BaseMainScreen.
Note:-- create a class called Home and instead of extending MainScren , Simpley extend BaseMainScreen.

public final class Home extends BaseMainScreen implements FieldChangeListener
{
    /**
     * Creates a new Home object
     */
    public Home()
    {      
        setTitle("Amit Blogs");
        ButtonField submit=new ButtonField("Submit");
        submit.setChangeListener(this);
        add(submit);
    }

    public void fieldChanged(Field arg0, int arg1) {
        UiApplication.getUiApplication().pushScreen(new FirstPage());
    }
}
