I've got a JTable and I want to replace the existing text in a cell
when the cell is focused. What I have currently works if the cell is
double-clicked but if I tab to it, it appends the first letter typed
to the existing text and THEN replaces the text with subsequent key
strokes. How do I make tabbing act the same way as double-click?
Thanks in advance,
Nancy

CODE::
     table = new JTable(table_model){
    public Component prepareRenderer(TableCellRenderer renderer, int
rowIndex, int vColIndex){
    Component c = super.prepareRenderer(renderer, rowIndex, vColIndex);
    if (isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(184, 207, 229));
      final Component editor = getEditorComponent();
      SwingUtilities.invokeLater(new Runnable(){
   public void run(){
          ((JTextComponent)editor).selectAll();
        }
      });
    } else if (vColIndex == 7 && !isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(255, 204, 153));
    } else if ((vColIndex == 9 || vColIndex == 17) && !
isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(204, 255, 255));
    } else if (vColIndex == 13 && !isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(204, 204, 255));
    } else if (vColIndex == 15 && !isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(204, 255, 204));
    } else if (vColIndex == 11 && !isCellSelected(rowIndex, vColIndex)){
      c.setBackground(new Color(255, 255, 153));
    } else if (rowIndex % 2 == 0 && !isCellSelected(rowIndex, vColIndex))
{
      c.setBackground(new Color(255, 255, 230));
    } else {
      c.setBackground(getBackground());
    }
    return c;
     }

     public boolean editCellAt(int row, int column, EventObject e){
    boolean result = super.editCellAt(row, column, e);
    final Component editor = getEditorComponent();
    if (editor != null && editor instanceof JTextComponent){
       if (e == null){
        System.out.println("null");
        ((JTextComponent)editor).selectAll();
       } else {
        System.out.println("not null");
        SwingUtilities.invokeLater(new Runnable(){
        public void run(){
           ((JTextComponent)editor).selectAll();
        }
       });
    }
     }
     return result;
   }
};
