Thread: I Need help with my ActionListener, ActionPerformed and Operations

Hi,

I really need help with my chess manager program! I work with the MVC principal. My controller class implements ActionListener
Other classes contains JButtons, JTextField.. I have a program it reads a FEN notation and scans it. After that it puts the chess pieces on the board as the FEN describes. I need help with the code, i have to finish this its important for me. Thanks in advance guys!

Controller class:

package controller;
 
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.*;
 
import javax.swing.*;
 
import model.Fen;
import view.ControlPanel;
import view.InfoPanel;
import view.ChessBoardView;
 
 
public class Controller extends JFrame implements ActionListener
{
	private InfoPanel infopanel;
	private ControlPanel controlpanel;
	private Fen fen;
    private ChessBoardView chessboardview;
 
    public Controller()
    {
        super("Chess Manager");
        makeFrame();   
        makeMenuBar();
        this.pack();   
    }
 
    private void makeFrame(){
        setSize(1050, 1050);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
 
        setResizable( false );
 
        Container contentpane = super.getContentPane();
        contentpane.setLayout(new BorderLayout());
        contentpane.setBackground(new Color(204,229,255)); 
 
        controlpanel = new ControlPanel(this);
        contentpane.add(controlpanel, BorderLayout.EAST);
 
        infopanel = new InfoPanel();
        contentpane.add(infopanel, BorderLayout.SOUTH);
 
        chessboardview = new ChessBoardView();
        contentpane.add(chessboardview, BorderLayout.WEST);     
    }
 
    private void makeMenuBar(){
        JMenuBar menubar = new JMenuBar();
        super.setJMenuBar(menubar);
 
        JMenu fileMenu = new JMenu("File");
        menubar.add(fileMenu);
 
        JMenu editMenu = new JMenu("Edit");
        menubar.add(editMenu);
 
        JMenu optionMenu = new JMenu("Options");
        menubar.add(optionMenu);
 
        JMenu extraMenu = new JMenu("Extra");
        menubar.add(extraMenu);
    }
 
	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
 
	}
}

ControlPanel class:

package view;
 
import java.awt.*;
import java.awt.event.*;
 
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JSlider;
 
import controller.Controller;
import model.ChessBoard;
import model.ChessPiece;
import model.Fen;
import model.Square;
import view.ChessBoardView;
 
public class ControlPanel extends JPanel
{
	private JPanel buttonpanel;
    private JButton btnEmptyBoard, btnInitialPosition;
	private JSlider sldVolume;
 
	private Fen fen;
	private ChessBoardView chessboardview;
	private InfoPanel infopanel;
 
	public ControlPanel (Controller controller)
	{
		setLayout(new GridBagLayout());
		setBackground(new Color(204,229,255));
 
		GridBagConstraints gbc = new GridBagConstraints();
		gbc.insets = new Insets(10,0,0,30);
 
 
		btnEmptyBoard = new JButton("Empty Board");
		gbc.gridy = 0;
		btnEmptyBoard .setPreferredSize(new Dimension(180, 25));
		//btnEmptyBoard .addActionListener(controller);
		btnEmptyBoard .setRequestFocusEnabled(false);
		add(btnEmptyBoard, gbc);
 
		btnInitialPosition = new JButton("Initial Position");
		gbc.gridy =1;
		btnInitialPosition .setPreferredSize(new Dimension(180, 25));
		btnInitialPosition .addActionListener(controller);                               <<<<<<<<<<<<<< actionlistener with controller parameter
 
		btnInitialPosition .setRequestFocusEnabled(false);
		add(btnInitialPosition, gbc);
		}	
 
		public JButton getButton(){
			return btnInitialPosition;
		}
}

InfoPanel class:

package view;
 
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.JPanel;
import javax.swing.JTextPane;
import javax.swing.JTextField;
import javax.swing.JTextArea;
import javax.swing.BorderFactory;
 
import model.Subscription;
import model.Fen;
import controller.Controller;
import view.ChessBoardView;
 
import controller.Controller;
 
 
 
public class InfoPanel extends JPanel
{
	private Subscription subscription;
	private Fen fen;
	private ChessBoardView chessboardview;
	private JTextField subscriptionbar;
    private JTextField fenbar;
    private JTextArea infobar;
 
    public InfoPanel (Controller controller){
 
        setLayout(new GridBagLayout());
        setBackground(new Color(204,229,255));
 
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.insets = new Insets(10,0,10,0);
 
        subscriptionbar = new JTextField(new Subscription().getSubscription());
        gbc.gridy = 0;
        subscriptionbar .setPreferredSize(new Dimension(500, 25));
        subscriptionbar .setBorder(BorderFactory.createLineBorder(Color.BLACK));
        add(subscriptionbar, gbc);
 
        fenbar = new JTextField(new Fen().getFen());
        gbc.gridy = 1;
        fenbar .setPreferredSize(new Dimension(500, 25));
        fenbar .setBorder(BorderFactory.createLineBorder(Color.BLACK));
        fenbar .addActionListener(controller);
        add(fenbar, gbc);
 
        infobar = new JTextArea();
        gbc.gridy = 2;
        infobar .setPreferredSize(new Dimension(500, 150));
        infobar .setBorder(BorderFactory.createLineBorder(Color.BLACK));
        infobar .setEditable(false);
        add(infobar, gbc); 
    }
 
    public String getFen(){
    	return fenbar.getText();
    }
}

the code has to to something like this
String input = fenbar.getText();
fen.scanner(input);
fen.scanFen();
chessboardview.addSquaresAndPiecesToPanel();

I need help with the code

The probability of getting help goes up substantially if you ask a specific question. I for one can only guess as to the problem.
