Question

Developing on the blackberry (OS 7.0) and I have an extended Vertical Field manager created as such:

_myVFM = new MyViewManager(Manager.USE_ALL_WIDTH | Manager.USE_ALL_HEIGHT | Manager.VERTICAL_SCROLL){};

However, when I scroll the view, the virtual scroll view size appears way too big.
i.e, I can scroll quite alot further down than is needed and I cant work out why?

Any body any quick ideas? I do have a background image in there that is created as such:

public void paint(Graphics graphics)
{
    Bitmap backgroundBitmap = Bitmap.getBitmapResource("bg.png");
    Bitmap newBackground = new Bitmap(Display.getWidth(), Display.getHeight());
    backgroundBitmap.scaleInto(newBackground, Bitmap.FILTER_LANCZOS, Bitmap.SCALE_TO_FILL);

    graphics.clear();
    graphics.drawBitmap(0, 0, Display.getWidth(),            
             Display.getHeight(), newBackground, 0, 0);                 
    super.paint(graphics);
}

Please and thanks,

Answer 1

    public MyScreen() {
    super(NO_VERTICAL_SCROLL);

I managed to fix the issue in my extension of MainScreen using ‘NO_VERTICAL_SCROLL’ style parameter

Combined with Rupak’s suggestion of setting the Background in the constructor of my Vertical Field Manager rather than overriding paint (

everything seems Good now – thanks all for your help.
