Java Swing JTable Simple Doubt

[hemanthjava]

Hello there,

In the below code of a JTable Example I wanted to know how to print a cell value when you double click on a cell. I was wrong in my logic. Could someone help me with this. I tried using a Point Class.

import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.Point;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.TableModel;

public class JTableDoubtDemo extends JPanel {

	public JTableDoubtDemo() {
		super(new GridLayout(1, 0));

		String[] columnHeaders = { "First Name", "Last Name", "Subject",
				"Ecode", "Pass/Fail" };

		Object[][] data = {
				{ "Bob", "Marley", "English", new Integer(35),
						new Boolean(false) },
				{ "Rob", "barley", "German", new Integer(63), new Boolean(true) } };

		final JTable jtab = new JTable(data, columnHeaders);
		jtab.setPreferredScrollableViewportSize(new Dimension(500, 70));
//		table.setFillsViewportHeight(true);

		jtab.addMouseListener(new MouseAdapter() {
			public void mouseClicked(MouseEvent e) {
				printDebugData(jtab);
			}
		});

		//Create the scroll pane and add the table to it.
		JScrollPane scrollPane = new JScrollPane(jtab);

		//Add the scroll pane to this panel.
		add(scrollPane);
	}

	private void printDebugData(JTable table) {
		
		Point p = table.getMousePosition();
		int x = (int)(p.getX());
		int y = (int)(p.getY());
		System.out.println(x+"\t"+y);
		TableModel model = table.getModel();
		System.out.println("Value of data : "+model.getValueAt(x, y));
	
	}

	private static void createAndShowGUI() {

		JFrame frame = new JFrame("JTable Example");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		//Create and set up the content pane.
		JTableDoubtDemo contentPane = new JTableDoubtDemo();
		contentPane.setOpaque(true); //content panes must be opaque
		frame.setContentPane(contentPane);

		frame.pack();
		frame.setVisible(true);
	}

	public static void main(String[] args) {

		javax.swing.SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				createAndShowGUI();
			}
		});
	}
}
