Re: How to use actionListers within static methods

In the code below I am attempting to define an ActionListener for a
button so I can do something useful when the button is pressed.

At the statement
    ButtonListener buttonListener = new ButtonListener();
Eclipse says "No enclosing instance of type Hats is accessible, Must
qualify the allocation with an enclosing instance of type Hats (e.g.
x.new A() where x is an instance of Hats".

The trouble is I never intend to instantiate Hats since I don't ever
expect to need multiple Hats objects in existence at the same time.

Q.1 Is there a fix?

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.*;

public class StaticGUI {
  public static JFrame frame = new JFrame();
  public static void main(String[] args) {
    // main GUI with menu that invokes ...
    Hats.editHats();
  }
}

class Hats {
  // so can refer to addButton in buttonListener:
  public static JButton addButton;

  public static void editHats() {
    addButton = new JButton("Add");
    JButton editButton = new JButton("Edit");
    JButton removeButton = new JButton("Remove");
    ButtonListener buttonListener = new ButtonListener();
    addButton.addActionListener(buttonListener);
    editButton.addActionListener(buttonListener);
    removeButton.addActionListener(buttonListener);
    JPanel buttonPanel = new JPanel();
    buttonPanel.add(addButton);
    buttonPanel.add(editButton);
    buttonPanel.add(removeButton);
    JPanel panel = new JPanel();
    panel.setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS));
    JTextArea textArea = new JTextArea();
    panel.add(textArea);
    panel.add(buttonPanel);
    JOptionPane pane = new JOptionPane(
        panel, // "message"
        JOptionPane.PLAIN_MESSAGE, // messagetype
        JOptionPane.OK_CANCEL_OPTION // optiontype
    );
    JDialog dialog = pane.createDialog(StaticGUI.frame,"Test");
    dialog.setResizable(true);
    dialog.setVisible(true);
  } // method editHats

  // an inner class within Hats, to listen to Hat-related button events
  class ButtonListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
      JComponent c = (JComponent) e.getSource();
      if (c == addButton) {
        System.out.println ("You pressed 'Add'");
      }
    }
  }
} // class Hats

Q.2 should I rethink my whole approach to my design of this application?
