Tabbed Pane Problem

Question

Im working on a program that keeps track of the progress and budget of different projects. Each project is given its own tab. I am already at the point where i can create and delete tabs using ActionListeners. What i need to be able to do is to have the same JLabels show differnt data, eg. the projects budget, on each tab. Right now when i click the button to change the JLabel to display the projects budget, it will change it on the tab i am on if only one tab is open. If more than one tab is open, it will only change the JLabel on the last tab to be created no matter which tab i press the button on.
Each tab has 12 panels on it, one for each month. And each of the 12 panels has it own edit button. I need to be able to edit each individual label on each of the 12 panels without affecting the panels of the other tabs.
I cant have multiple JLabels because there is no way for me to know how many projects will be created and deleted.
Is there any way for me to have the edit button's ActionListener distinguish between which of the 12 panels, and which of the tabs i am using?
Thanks,
Ross

Thanks for the tip. Heres my code
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class ForumEx
  JTabbedPane tab;
  JMenuBar menuBar;
  JMenu menu;
  JMenuItem menuItem;
  JFrame frame;
  JPanel mainPanel;
  JLabel originalText;
  JLabel label;
  JTextField nameInput;
  String projectName;
  public static void main(String[] args)
    ForumEx ar = new ForumEx();
  public ForumEx()
    JFrame frame = new JFrame("");
    tab = new JTabbedPane();
    //frame.add(tab, BorderLayout.CENTER);
    mainPanel = new JPanel();
    JPanel panel = new JPanel();
    tab.add("Example Project 1", panel);
    frame.add(tab);
    menuBar = new JMenuBar();
    menu = new JMenu("Projects");
    menu.setFont(new Font("Arial Unicode MS", Font.BOLD, 13));
    menuBar.add(menu);
    menuItem = new JMenuItem("   New Project      ");
    menuItem.setFont(new Font("Arial Unicode MS", Font.PLAIN, 13));
    menuItem.addActionListener(new AddProject());
    KeyStroke ctrlNKeyStroke = KeyStroke.getKeyStroke("control N");
    menuItem.setAccelerator(ctrlNKeyStroke);
    menu.add(menuItem);
    mainPanel.add(menuBar);
    frame.add(mainPanel, BorderLayout.NORTH);
    frame.setSize(400, 400);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  public class AddProject implements ActionListener
    public void actionPerformed(ActionEvent e)
          frame = new JFrame("New Project");
          JPanel mainPanel = new JPanel(new GridLayout(1,2));
          JPanel buttonPanel = new JPanel();
          JButton create = new JButton("Create");
          create.setFont(new Font("Arial Unicode MS", Font.BOLD, 13));
          JRootPane rootPane = frame.getRootPane();
          rootPane.setDefaultButton(create);
          create.addActionListener(new Create());
          buttonPanel.add(create);
          label = new JLabel("Project Name:     ");
          label.setFont(new Font("Arial Unicode MS", Font.PLAIN, 13));
          mainPanel.add(label);
          nameInput = new JTextField(15);
          mainPanel.add(nameInput);
          mainPanel.add(buttonPanel);
          frame.add(mainPanel);        
          frame.pack();
          frame.setVisible(true);
  public class Create implements ActionListener
    public void actionPerformed(ActionEvent e)
          if(tab.getTabCount() == 0)
                mainPanel.add(tab);
          String empty = "";
          projectName = nameInput.getText();
          JButton changeText = new JButton("Change Text");
          changeText.addActionListener(new ChangeText());
          JPanel panel2 = new JPanel(new GridLayout(2,1));
          originalText = new JLabel("Original Text");
          panel2.add(originalText);
          panel2.add(changeText);
          tab.add("  " + projectName + "  ", panel2);
          tab.setFont(new Font("Arial Unicode MS", Font.PLAIN | Font.ITALIC, 13));
          frame.setVisible(false);
          frame.dispose();
  public class ChangeText implements ActionListener
    public void actionPerformed(ActionEvent e)
          originalText.setText("NEW TEXT");
}maybe now i can better explain my problem. When you run this, click "Projects", name the project "1" and click create. Now if you click the change text button, the label will change to what i set. Click projects again, name this one "2". Click the button. Again the label changes without affecting the first one. But heres where the problem is, create two more tabs named "3" and "4". Now on tab 3, click the change text button. The label on that page wont change, but if you go to tab "4" the label will be changed. I know that the button is only affecting the most recently created label.
Again, what im looking to do is to be able to have each button only affect the label of its own panel). And much later in this project there will be a ActionListener that will get what the label says, but i need it to be able to get the text of the label of the tab that i am on, not just the most recently created.
Thanks again,
Ross
