jtable combo box value

[gowtham cow]

how to get the combo box selected value in jtable in event

like tablemodellistener

i tryed

getRightPanel().getProtocolOptionsTreeTablePanel().getTreeTable().getModel().addTableModelListener(new javax.swing.event.TableModelListener
() {
public void tableChanged(TableModelEvent e) {


int i=getRightPanel().getProtocolOptionsTreeTablePanel().getTreeTable().getSelectedRow();
int j=getRightPanel().getProtocolOptionsTreeTablePanel().getTreeTable().getSelectedColumn();
String ss=getRightPanel().getProtocolOptionsTreeTablePanel().getTreeTable().getValueAt(i,j).toString();
System.out.println(i+"row"+j+"value"+ss);



}
});

please help me

"gowtham cow",
Check your Private Messages. You've already been told to do so a couple of times. This is your last warning.

The TableModelEvent has all the information you need to get the current value in the model:

    
import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;

public class TableProcessing extends JFrame implements TableModelListener
{
	public TableProcessing()
	{
		super("Table");
		String[] columnNames = {"Item", "Quantity", "Price", "Cost"};
		Object[][] data =
		{
			{"Bread", new Integer(1), new Double(1.11), new Double(1.11)},
			{"Milk", new Integer(1), new Double(2.22), new Double(2.22)},
			{"Tea", new Integer(1), new Double(3.33), new Double(3.33)},
			{"Cofee", new Integer(1), new Double(4.44), new Double(4.44)}
		};

		DefaultTableModel model = new DefaultTableModel(data, columnNames);
		model.addTableModelListener( this );

		JTable table = new JTable( model )
		{
			//  Returning the Class of each column will allow different
			//  renderers to be used based on Class
			public Class getColumnClass(int column)
			{
				return getValueAt(0, column).getClass();
			}

			//  The Cost is not editable
			public boolean isCellEditable(int row, int column)
			{
				int modelColumn = convertColumnIndexToModel( column );
				return (modelColumn == 3) ? false : true;
			}
		};
		table.setPreferredScrollableViewportSize(table.getPreferredSize());

		JScrollPane scrollPane = new JScrollPane( table );
		getContentPane().add( scrollPane );


		String[] items = { "Bread", "Milk", "Tea", "Coffee" };
		JComboBox editor = new JComboBox( items );

		DefaultCellEditor dce = new DefaultCellEditor( editor );
		table.getColumnModel().getColumn(0).setCellEditor(dce);
	}

	/*
	 *  The cost is recalculated whenever the quantity or price is changed
	 */
	public void tableChanged(TableModelEvent e)
	{
		if (e.getType() == TableModelEvent.UPDATE)
		{
			int row = e.getFirstRow();
			int column = e.getColumn();

			if (column == 1 || column == 2)
			{
				TableModel model = (TableModel)e.getSource();
				int	quantity = ((Integer)model.getValueAt(row, 1)).intValue();
				double price = ((Double)model.getValueAt(row, 2)).doubleValue();
				Double value = new Double(quantity * price);
				model.setValueAt(value, row, 3);
			}
		}
	}

	public static void main(String[] args)
	{
		TableProcessing frame = new TableProcessing();
		frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
		frame.pack();
		frame.setLocationRelativeTo( null );
		frame.setVisible(true);
	}
