Problem adding action event to cells in JTable

Question

hi frends i m developing file transfer client server.My client GUI contains JTable in which it displays directory and file in the current directory.Now i want to display files under the directory when i double click on the directory bt it doesnt happen though i hav applied event to the cell.My code is as below:
The FileTransfer.java cotains code for table as::
File dir=new File(".");
localTable=new JTable(new FileTableModel(dir));
localTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
localTable.getColumnModel().getColumn(0).setCellRenderer(new FileTableCellRenderer());
The file FileTableModel.java is
public class FileTableModel extends AbstractTableModel {
private File dir;
private File[] list;
private String[] columnNames = new String[] {
     "Name", "Size", "last modified"};
public FileTableModel(File dir) {
setDirectory(dir);
public void setDirectory(File dir) {
this.dir = dir;
list = dir.listFiles();
public int getRowCount() {
return list.length;
public int getColumnCount() {
return 3;
public String getColumnName(int col) {
     return columnNames[col];
public Object getValueAt(int row, int col) {
switch(col) {
case 0:
return list[row];
case 1:
return list[row].isDirectory()?"Dir":(list[row].length()+"");
case 2:
return new Date(list[row].lastModified());
default:
return null;
public Class getColumnClass(int col) {
switch (col) {
case 0:
return File.class;
case 1:
return String.class;
case 2:
return Date.class;
default:
return null;
and FileTableCellTandrer.java is
public class FileTableCellRenderer implements TableCellRenderer {
     public FileTableCellRenderer(){
public Component getTableCellRendererComponent(final JTable table,final Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
JTextField fileField = new JTextField(((File)value).getName());
Color normalBackground = Color.white;
Color selectedBackground = Color.gray;
Color focusBackground = Color.green;
fileField.setBackground(normalBackground);
if (isSelected) {
fileField.setBackground(selectedBackground);
if (hasFocus) {
fileField.setBackground(focusBackground);
fileField.setEnabled(false);
if (((File)value).isDirectory()) {
     fileField.setEnabled(true);
     System.out.println("Inside isDirectory");
fileField.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent ae) {
          ((FileTableModel)table.getModel()).setDirectory((File)value);
          ((AbstractTableModel)table.getModel()).fireTableDataChanged();
return fileField;
so plz help me out.Is there any change needed in my code of FileTableCellRenderer thn tell me.

Make the cells non-editable then use a MouseListener on the table and handle the double click.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
