JList problems

[grimx]

When i run the following code;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

import java.io.*;

public class TestJList extends JFrame {
	private JList jList;
	private String[] files;
	private File file;
	private JTextArea textArea;
	
	public TestJList(String fname) {
		setSize(650, 500);
		setTitle("TestJList Demo");
		setLocationRelativeTo(null);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		
		
		file = new File(fname);
		files = file.list();
		jList = new JList(files);
		jList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
		jList.addListSelectionListener(new ListSelectionListener() {

			@Override
			public void valueChanged(ListSelectionEvent e) {
				String line = (String)jList.getSelectedValue();
				textArea.append(new File(line).getPath());
				
			}
			
		});
		JScrollPane JList_sp = new JScrollPane(jList);
		add(JList_sp, BorderLayout.WEST);
		
		textArea = new JTextArea(10, 80);
		
		JScrollPane textArea_sp = new JScrollPane(textArea);
		add(textArea_sp, BorderLayout.CENTER);
		
		setVisible(true);
	}
	
	public static void main(String[] args) {
		TestJList frame = new TestJList()); //input some directory
	}

}

When i select a file/directory from the list it is printed twice in the JTextArea.

Only respond if the selected value isn't adjusting. For example:

      jList.addListSelectionListener(new ListSelectionListener() {

         @Override
         public void valueChanged(ListSelectionEvent e) {
            if (!e.getValueIsAdjusting()) {
               // String line = files[jList.getSelectedIndex()] + "\n";
               String line = (String) jList.getSelectedValue();
               // textArea.append(new File(line).getPath());
               textArea.append("i\n");
            }
         }
      });
