local FileTableModel

[Satanduvel]

Hey i have a "problem" with mine FileTableModel. I get al the values in my JTable but there isn't a ".." directory in the JTable. So i want to create a row with the option to go 1 directory up. How do i do that?

dir = new File("C:\\java");
            FileTableModel model = new FileTableModel(dir);
 
            TableSorter sorter1 = new TableSorter(model);
            table = new JTable(sorter1);
 
            sorter1.setTableHeader(table.getTableHeader());
            sorter1.setSortingStatus(0, -1);
 
            TableColumn column = null;
            for (int i = 0; i < 3; i++) {
                column = table.getColumnModel().getColumn(i);
                if (i == 0) {
                    column.setPreferredWidth(20);
                } else {
                    if (i == 1){
                        column.setPreferredWidth(160);
                    }
                    else
                    {
                        column.setPreferredWidth(80);
                    }
                }
            }
            ListSelectionModel listMod1 =  table.getSelectionModel();
            listMod1.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
            listMod1.addListSelectionListener(this);
 
            table.addMouseListener(this);
            tLocal.setText(dir.getPath());
            table.getTableHeader().setReorderingAllowed(false);
            table.setRowHeight(20);
 
            scrClient = new JScrollPane(table);

The filetable is created with this code:

class FileTableModel extends AbstractTableModel {
          protected File dir;
          protected String[] filenames;
 
          protected String[] columnNames = new String[] {
            "","name", "size", "last modified", "directory?", "readable?", "writable?"
          };
 
          protected Class[] columnClasses = new Class[] { 
            Icon.class,String.class, Long.class, Date.class, 
              Boolean.class, Boolean.class, Boolean.class
          };
 
          // This table model works for any one given directory
          public FileTableModel(File dir) { 
            this.dir = dir; 
            this.filenames = dir.list();  // Store a list of files in the directory
          }
 
          // These are easy methods
          public int getColumnCount() { return 3; }  // A constant for this model
          public int getRowCount() { return filenames.length; }  // # of files in dir
 
          // Information about each column
          public String getColumnName(int col) { return columnNames[col]; }
          public Class getColumnClass(int col) { return columnClasses[col]; }
 
          // The method that must actually return the value of each cell
          public Object getValueAt(int row, int col) {
            File f = new File(dir, filenames[row]);
            switch(col) {
            case 0: return f.isDirectory() ? folder : files;
            case 1: return filenames[row];
            case 2: if (f.isDirectory()==true){
                            return null;
                        }else{
                            return new Long(f.length());
                        }
            case 3: return f.isDirectory() ? Boolean.TRUE : Boolean.FALSE;
            case 4: return f.canRead() ? Boolean.TRUE : Boolean.FALSE;
            case 5: return f.canWrite() ? Boolean.TRUE : Boolean.FALSE;
            default: return null;
            }
          }
         }
