Graphics in a Class

Hi,
I'm writing a class that displays an image and can be called from an Applet or something.
Anyway, I have a function setGraphics(Graphics g) which sets a global graphics variable to the parameter passed to it, so it can use the same drawing area as the Applet.
It then sets the image using this code:
BObject=Toolkit.getDefaultToolkit().getImage("somefile.jpg");
and then uses the graphics object to draw it:
grObject.drawImage(BObject, 10, 10, this);
But I get a Cannot Resolve Symbol error and I'm not sure why - the documentation says that drawImage is part of the Graphics class.
Am I mising an import or something? I have the following imports:
import java.awt.*;
import java.applet.*;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.*;

Any help would be appreciated.

does the class making the call implement ImageObserver?

try:

grObject.drawImage(BObject, 10, 10, null);
