import net.rim.device.api.ui.Graphics;

public class MyField extends Field{
    private int ttwidth;
    private int hhheight;
    private Graphics graphic;
    
    public MyField() {
        
    }
    
    protected void layout(int width, int height) {
        ttwidth = Display.getWidth();
        hhheight = Display.getHeight();

Re: Making new Graphics problem

you get the graphics object as a parameter, and as it is empty you can do whatever you want with it, no need to create a bitmap or a new graphics object.
