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;
		    }
		  }
		 }
