i am developing a blackberry app. i want to paint the screen. i have implemented this
VerticalFieldManager hfmBg = new VerticalFieldManager(Field.USE_ALL_HEIGHT )
            {
                protected void paint(Graphics g)
                {
                    g.setBackgroundColor(Color.SILVER);
                    g.clear();
                    super.paint(g);
                }//end of paint method
            };//end of vertical field manager
but tell me is there any other approach to paint the whole screen?
