Override the ToolTipText of the JTable with JButton ToolTipTex(pls see msg)

Question

Hi All,
Could you please me to solve this problem?
I have two Icons display on 2 JButtons (2 different ToolTipText for buttons). The Buttons are display on a JPanel. The Panel is display on one of the cell inside JTable. Is it possible that when I move the mouse over each Icon it will displays the ToolTipText of each of the JButton (I am try to replace the ToolTipText of the JTable with the ToolTipText of the JButton when mouse over and when I move the mouse to the next JButton I get a different ToolTipText). The reason I am using the JButton is that in the future I will add actionListener() to do something when the user click on it.
I have try working with glassPane, addMouseMotionListener, MouseEvent.getPoint(), SwingUtilities.convertPoint, SwingUtilities.getDeepestComponentAt.
Thank you in advance.
Note: I am getting the Icons from Object [].

Hello, the following is one ugly piece of code but I guess that's pretty much what you were after. Just test the tooltip and you'll see that it depends both on the cell and on which of the two buttons is hovered.import javax.swing.*;
import javax.swing.table.TableCellRenderer;
import java.awt.*;
import java.awt.event.MouseEvent;
public class TestTooltipTable {
     private static class CustomTableCellRenderer implements TableCellRenderer {
          private JButton theLeftButton;
          private JButton theRightButton;
          private JPanel thePanel;
          public CustomTableCellRenderer() {
               theLeftButton = new JButton("left action");
               theRightButton = new JButton("right action");
               thePanel = new JPanel(new GridLayout(1, 2)) {
                    public String getToolTipText(MouseEvent e) {
                         Point p = e.getPoint();
                         Rectangle leftRect = theLeftButton.getBounds();
                         Rectangle rightRect = theRightButton.getBounds();
                         if (leftRect.contains(p)) {
                              return theLeftButton.getToolTipText();
                         } else if (rightRect.contains(p)) {
                              return theRightButton.getToolTipText();
                         return " ";
               thePanel.add(theLeftButton);
               thePanel.add(theRightButton);
          public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
                                                                    boolean hasFocus, int row, int column) {
               String text = (String)value;
               theLeftButton.setToolTipText("left action " + text);
               theRightButton.setToolTipText("right action " + text);
               return thePanel;
     public static void main(String[] args) {
          final JFrame frame = new JFrame(TestTooltipTable.class.getName());
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          Object[][] data = {{"1", "A"}, {"2", "B"}, {"3", "C"}};
          String[] columnNames = {"Number", "Letter"};
          JTable table = new JTable(data, columnNames) {
               public String getToolTipText(MouseEvent event) {
                    return super.getToolTipText(event);
          table.setDefaultRenderer(Object.class, new CustomTableCellRenderer());
          ToolTipManager.sharedInstance().registerComponent(table);
          frame.getContentPane().add(new JScrollPane(table));
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
                    frame.pack();
                    frame.show();
}
