Mouse click in JTable

Question

Hi All,
I want to force mouse click when right clicking on a JTable. I mean when the right click is done in the mouse, the left click should be forced. I have a JTable with some values in it. I want to select the particular column in the table when right click mouse action. How can I do it?
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class TableDemo extends JFrame
    private JTable table;
    private JScrollPane jsp;
    private JPanel jp;
    public TableDemo()
        initComponents();
    private void initComponents()
        jp = new JPanel();
        String columnNames[] = { "Column 1", "Column 2", "Column 3" };
        String dataValues[][] =
            { "12", "234", "67" },
            { "-123", "43", "853" },
            { "93", "89.2", "109" },
            { "279", "9033", "3092" }
        table = new JTable(dataValues, columnNames);
        jsp = new JScrollPane(table);
        jsp.setViewportView(table);
        jp.add(jsp);
        table.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent evt) {
                if(evt.getButton() == 3) {
                    System.out.println("Right Click........");
                    // Mouse left click should be forced here to select the row.
                if(evt.getButton() == 1) {
                    System.out.println("Mouse LEFT CLICK FORCED.....");
        getContentPane().add(jp);
        pack();
        setVisible(true);
    public static void main(String args[])
        new TableDemo();
}

There may be a better way, but you could just use java.awt.Robot to perform the left click. I've changed your code around a bit: it shouldn't extend JFrame as it is in no way a special type of JFrame. And a GUI should always be launched on the EDT.**import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ForceLeftClick {
   private JTable table;
   private void makeUI() {
      String columnNames[] = {"Column 1", "Column 2", "Column 3"};
      String dataValues[][] = {
         {"12", "234", "67"},
         {"-123", "43", "853"},
         {"93", "89.2", "109"},
         {"279", "9033", "3092"}
      table = new JTable(dataValues, columnNames);
      JScrollPane scrollPane = new JScrollPane(table);
      scrollPane.setViewportView(table);
      table.addMouseListener(new MouseAdapter() {
         @Override
         public void mouseClicked(final MouseEvent evt) {
            if (evt.getButton() == MouseEvent.BUTTON3) {
               System.out.println("Right Click........");
               // Mouse left click should be forced here to select the row.
               //final Point point = evt.getLocationOnScreen();
               SwingUtilities.invokeLater(new Runnable() {
                  @Override
                  public void run() {
                     try {
                        Robot robot = new Robot();
                        //robot.mouseMove(point.x, point.y);
                        robot.mousePress(InputEvent.BUTTON1_MASK);
                        robot.mouseRelease(InputEvent.BUTTON1_MASK);
                     } catch (AWTException ex) {
                        ex.printStackTrace();
            if (evt.getButton() == MouseEvent.BUTTON1) {
               System.out.println("Mouse LEFT CLICK FORCED.....");
      JFrame frame = new JFrame();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.add(scrollPane);
      frame.pack();
      frame.setVisible(true);
   public static void main(String args[]) {
      SwingUtilities.invokeLater(new Runnable() {
         @Override
         public void run() {
            new ForceLeftClick().makeUI();
}If there are issues of Robot clicking in the wrong location because the user moves the mouse before the robot does its stuff (not likely, but..), uncomment the two commented lines.

**edit And always use constant fields by name, not magic numbers. MouseEvent.BUTTON1, not 1. That keeps your code implementation independent.
