BlackBerry:禁用垂直滚动

Question

在BlackBerry我开发了一个屏幕,在背景中显示大小为480×360的图像.我的BB屏幕大小为480×360.由于图像有点大,当我垂直滚动时,屏幕会滚动并扰乱我的屏幕.我想锁定滚动,这样我就无法进行垂直滚动.可能是我问一个非常简单的问题,但我现在没有时间去谷歌了.请帮我这样做

我的代码如下:

public LaunchXtcMsngrScreen()
{
    int intwidth = Display.getWidth();
    int intheight = Display.getHeight();


    //getting the height/width of BB screen
    Debugger.debug(UrlInfo.workflow_File,"Screen Height ="+intheight);
    Debugger.debug(UrlInfo.workflow_File,"Screen Width ="+intwidth);

    BMbackground = Bitmap.getBitmapResource("xtclogo.jpg");

    VerticalFieldManager VFM = new VerticalFieldManager(VerticalFieldManager.USE_ALL_WIDTH 
                                                                | VerticalFieldManager.USE_ALL_HEIGHT
                                                                | VerticalFieldManager.NO_VERTICAL_SCROLL
                                                                | VerticalFieldManager.NO_VERTICAL_SCROLLBAR)
    {
        //Override the paint method to draw the background image.
        public void paint(Graphics graphics)
        {   
            //Draw the XTC Messenger logo
            graphics.drawBitmap(0, 0,Display.getWidth(),Display.getHeight(),BMbackground, 0, 0);
            super.paint(graphics);
        }
    };

    Bitmap registerbitmap = Bitmap.getBitmapResource("register_button.PNG");
    BFregister = new ImageButtonField(registerbitmap);

    BFregister.setMargin(245,0,0,190);//vertical pos,0,0,horizontal pos

    VFM.add(BFregister);
    add(VFM);

}

将以下代码添加为函数声明的下一行

超(NO_VERTICAL_SCROLL | NO_VERTICAL_SCROLLBAR);
