Next component to get focus?

Question

Hey Guys,
If i had a panel with buttons and other components and if the focus is on one of the buttons, is it possible to have java return what the next component to get the focus is? I know there's a getNextFocusableComponent, but i'd rather use something that is deprecated so any suggestion is welcomed.
Here's my code, I basically want the focus to go to button3 when it gets to the last cell in the table. I want the java to figure out the next component because I would rather not hard-code anything into this. Thanks guys!
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TestGui {
public static void main(String[] args) {
TestGuiFrame frame = new TestGuiFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
class TestGuiFrame extends JFrame {
public TestGuiFrame() {
setTitle("Pete's Test GUI");
setSize(200, 200);
Container contentPane = getContentPane();
JPanel panel = new JPanel();
JButton button1 = new JButton("button1");
JButton button2 = new JButton("button2");
JButton button3 = new JButton("button3");
JButton button4 = new JButton("button4");
JTable table1 = new JTable(2, 3);
panel.add(button1);
panel.add(button2);
panel.add(table1);
panel.add(button3);
panel.add(button4);
contentPane.add(panel);
InputMap im = table1.getInputMap(JTable.
WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
KeyStroke tab = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0);
final Action oldTabAction = table1.getActionMap().get(im.get(tab));
Action tabAction = new AbstractAction() {
public void actionPerformed(ActionEvent e) {
oldTabAction.actionPerformed(e);
JTable table = (JTable) e.getSource();
int rowCount = table.getRowCount();
int columnCount = table.getColumnCount();
int row = table.getSelectedRow();
int column = table.getSelectedColumn();
if (row == (rowCount-1) && column == (columnCount-1)) {
//set focus to next component <---- HELP NEEDED HERE =)
table1.getActionMap().put(im.get(tab),tabAction);
}

I haven't tried it but you should be able to do something like:
KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager()
FocusTraversalPolicy policy = manager.getDefaultFocusTraversalPolicy()
Component c = policy.getComponentAfter(....);Otherwise, maybe the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/misc/focus.html]How to Use the Focus Subsystem will help.
