Here is some skeleton code:

public class MyBClass extends JPanel implements MouseListener {

public MyAClass aClass;

public MyBClass(JPanel panel) {

if(panel instanceof MyAClass) {

aClass = (MyAClass)panel;

}

}

public void mousePressed(MouseEvent e) {

if(aClass != null) {

aClass.setSomeXValue( e.getX() );

}

}

}
