Turning an icon into a button in a table

Question

Currently, I access a database in my program, and if I find an 'X' in a specific column, I place an icon in that field. What I would like to do is have that icon act as a button, that will pop up a screen with further information about the table line item. I am new at Java, and not sure what to do next.
Here is the code for my table model:
class sciTableModel extends javax.swing.table.DefaultTableModel
     public sciTableModel()
          super();
     public sciTableModel(java.util.Vector data, java.util.Vector columnNames)
          super(data, columnNames);
and here is the code for my renderer
class IconRenderer extends DefaultTableCellRenderer
     public Component getTableCellRendererComponent(JTable table,
     Object value, boolean isSelected, boolean hasFocus, int row, int column)
          ImageIcon iconl = new ImageIcon("info.gif");
          String headerText = (String)value;
          // System.out.println(headerText);
          JLabel headerComponent =
          ((JLabel)super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column));
          headerComponent.setHorizontalAlignment(SwingConstants.CENTER);
          if (headerText != null)
               headerComponent.setIcon(iconl);
               headerComponent.setText("");
          else
               headerComponent.setIcon(null);
               headerComponent.setText(null);
          return headerComponent;
In the public class I set the renderer, and in the actionevent that runs the database access I use the tablemodel.
Any help on how I can turn this icon into a button would be appreciated.

In A JTable, the render has the job of drawing one or more cells, but it's a rubber stamp -- it doesn't
respond to events like a true component. What you describe isn't the job of an cell editor either,
since, obviously, nothing is being edited. That leaves JTable itself: I suggest you write a mouse
listener for your JTable and respond appropriately when the right cell is clicked:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test {
    public static void main(String[] args) {
        JTable table = new JTable(20, 5);
        table.addMouseListener(new MouseAdapter(){
            public void mousePressed(MouseEvent evt) {
                JTable t = (JTable) evt.getSource();
                Point point = evt.getPoint();
                int col = t.columnAtPoint(point);
                int row = t.rowAtPoint(point);
                if (col != -1 && row != -1) {
                    int modelCol = t.convertColumnIndexToModel(col);
                    System.out.println("clicked on model cell (" + row + "," + modelCol + ")");
        JFrame f = new JFrame("Test");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(table));
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
}As the code demonstrates, don't forget to translate from view columns to model columns.
By the way, why are you subclassing the default table model? You aren't changing any behavior...
