Spliting GUI code to multiple classes

Question

Hi All...
I am trying to design a large scale GUI, and after reading several MVC articles I still have some question on writing the GUI code.
for flexability I split the code to classes:
1) How can I notify on event(exp: actionPerformed), to other widgets located in separated classes which not visible(I attached a code describing this issue, every class would be in separated class)
Note
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
class BaseComp1 implements ActionListener{
    JButton button1;
    public void actionPerformed(ActionEvent e){
        // notify DrawingArea instance, an action performed
class BaseComp2 implements ActionListener{
    JButton button2;
    public void actionPerformed(ActionEvent e){
        // notify DrawingArea instance, an action performed
public class MainComp{ 
    BaseComp1 base1 ;
    BaseComp2 base2;
    public MainComp(){
        base1 = new BaseComp1();
        base2 = new BaseComp2();
public class drawingArea{
    public void drawStuff(){  // draw stuff when actionPerform in one of BaseComp* instance
public class GUI{
    drawingArea drawing;
    MainComp mainComp;
    public GUI(){       // need to connect BaseComp* instances in MainComp instance to
                        // notify drawingArea on actionPerform event
        drawing = new drawingArea();
        mainComp = new MainComp();
}2) If a solution is available but not recommended, is the preferred coding design for large GUI is to write all of it in the same class ?? any suggestion will excepted joyfully..
I would like to thanks in advance for any help
Best Regards

Answer 1

First of all, I think your code would improve if you don't have GUI classes implement Action or control interfaces. You may wish to have your controls in separate classes.
