James,

your table cell renderer is strange...I'm not an expert but I don't think
you need a setValue() method in it ... you need to implement a
getTableCellRendererComponent() method as below, from your earlier post you
can determine the cell coordinates which are passed as arguments to the
method. Otherwise your PcCharacter could be a class which contains the
character value and colurs associated with it.

public class PcCellRenderer extends DefaultTableCellRenderer {

 private JLabel blankLabel;
 private JLabel charLabel;
 private PcCharacter c;

 public Component getTableCellRendererComponent(JTable table, Object obj,
     boolean isSelected, boolean hasFocus, int row, int column) {

    if (obj == null)
        return blankLabel;

     c = (PcCharacter)obj;
    charLabel.setText(c.getValue());
    charLabel.setForeground(c.getForeground());
    charLabel.setBackground(c.getBackground());
    return charLabel;

 }
}

On the subject of initialising the values, you don't have to do it. Set up
your own Table Model as below, using a HashMap to only store values when you
actually have one:


public abstract class PcCellModel extends AbstractTableModel {

  private Map objectMatrix = new HashMap();
  private Point objectIndex = new Point(0,0);
  protected int maxCol = 55;
  protected int maxRow = 25;

  public PcCellModel () {
  }

  public PcCellModel (int row, int col) {
    maxRow = row;
    maxCol = col;
  }

  public Object getValueAt(int row, int col) {
    objectIndex.x = row;
    objectIndex.y = col;

    if (objectMatrix.get(objectIndex) == null)
      return null;

    return (PcCharacter)objectMatrix.get(objectIndex);
  }

  public void setValueAt(Object setObject, int row, int col) {
    if (setObject == null) {
      objectMatrix.remove(new Point(row, col));
    }
    else {
      maxCol = Math.max(col, maxCol);
      maxRow = Math.max(row, maxRow);
      objectMatrix.put(new Point(row, col), setObject);
    }
  }

  public int getRowCount() {
    return maxRow;
  }
  public int getColumnCount() {
    return maxCol;
  }
  public int getMaxColumn() {
    return maxCol;
  }
  public int getMaxRow() {
    return maxRow;
  }

  public boolean isCellEditable(int row, int col) {
    return false;
  }

}

I kind of cobbled this together but I hope it helps.
