Please Help: How to add a Checkbox field to a JTable

Question

Hi,
I am trying to add a checkbox filed to a JTable with DefaultTableModel.
I have tried fro hours. Just Does not work.
Here is my sample code:
DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
Object[] data;
data = new Object[2];
data[0]= "string"
data[2] = new Boolean(false)
model.addRow(data);     
What is missing in here?
Thanks,
Tara

Answer 1

you can do that with the help of DefaultTableModel alone
if u r so determined to use DefaultTableModel u need to have a subclass of it
following sample may satisfy u ...
import javax.swing.*;
import java.awt.*;
import java.beans.*;
import java.awt.event.*;
import javax.swing.table.*;
public class MyTable extends JApplet{
     Object o[] = {"Name","Address","city","Vegetarian"};
     Object data[][] = {
          {"a","a","pune",new Boolean(true)},
          {"Alison", "Huml","mumbai",new Boolean(true)}
     class model extends DefaultTableModel
          model(Object[][] data,Object[] cn)
               super(data,cn);
          public Class getColumnClass(int i)
               return getValueAt(0,i).getClass();
          public Object getValueAt(int i,int j)
               return data[i][j];
     model m = new model(data,o);
     JTable t1 = new JTable(m);
     public void init()
          Container c1 = new Container();
          c1 = getContentPane();
          c1.add(t1);
          TableColumn tc = t1.getColumnModel().getColumn(2);
          JComboBox jc = new JComboBox();
          jc.addItem("Pune");
          jc.addItem("Mumbai");
          jc.addItem("Madras");
          tc.setCellEditor(new DefaultCellEditor(jc));
