Hi Experts,
In my JTable , I am using custom cellRenderer to add the  icon depending upon value of cell.
Table cell shows icon followed by text, I need to open new JMessageDialog when user clicks this icon .

How I can add  mouselistner to this icon ?

public class DescriptionCellRenderer extends DefaultTableCellRenderer {
 
	
	 public Component getTableCellRendererComponent(JTable table, Object value,boolean isSelected, boolean hasFocus, int row, int column) {
 Component cell = super.getTableCellRendererComponent(table, value,isSelected, hasFocus, row, column);
		
		String val=value.toString();
		
		if (!val.equals("ok")){
							ImageIcon icon = new ImageIcon("help.gif");
			setText(val);
			setIcon(icon);
 
		}		
		return cell;
	 
	    }
 
	}

Open in new window

you don't, you add your listener to the table. Then calculate which cell was clicked using rowAtPoint(), and columnAtPoint()

I added listner to table , and now when I click on the cell new dialog will open.
Now this cell contains icon followed by text. And my requirement is ,when  user clicks on icon then only dialog message should open.and when he clicks on text ,nothing should happen.
How can listener identify difference between icon and text.?
Is it possible to get the cell value at perticular position?

Thanks in advance

yes, use the getValueAt() method of the table/model
