Question

I have a JTabbedPane with 2 tabs on it. When i launch my program the wrong tab comes up by default. How can I chage what tab is opened at run time. What code do I need for this?
Thanks

Answer 1

No. I use this code in several places.
JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.setSelectedIndex(2);
In fact, here goes an example of using this:
package test;
import java.awt.FlowLayout;
import java.awt.event.KeyListener;
import java.awt.event.KeyEvent;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemListener;
import java.awt.event.ItemEvent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JTabbedPane;
import javax.swing.ActionMap;
import javax.swing.InputMap;
import javax.swing.KeyStroke;
import javax.swing.JComboBox;
import javax.swing.SwingUtilities;
public class TestBug4 extends JFrame {
     JTextField textField;
     JComboBox comboBox;
    JTabbedPane tabbedPane;
     public TestBug4(String name) {
          super(name);
          JPanel panel1 = new JPanel(new FlowLayout());
          textField = new JTextField(10);
          panel1.add(textField);
          JPanel panel2 = new JPanel(new FlowLayout());
          JTextField textField2 = new JTextField(15);
          panel2.add(textField2);
          JPanel panel3 = new JPanel(new FlowLayout());
          comboBox = new JComboBox(new String[] {"One", "Two", "Three"});
          comboBox.setEditable(true);
          panel3.add(comboBox);
          comboBox.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    System.out.println("e = " + e);
          comboBox.addItemListener(new ItemListener() {
               public void itemStateChanged(ItemEvent e) {
                    System.out.println("e = " + e);
          tabbedPane = new JTabbedPane();
          tabbedPane.addTab("Tab 1", panel1);
          tabbedPane.addTab("Tab 2", panel2);
          tabbedPane.addTab("Tab 3", panel3);
          getContentPane().add(tabbedPane);
     public void setDefaultFocus() {
          tabbedPane.setSelectedIndex(2);
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
//                    textField.requestFocus();
                    comboBox.requestFocus();
     private class MyTabbedPane extends JTabbedPane {
          public MyTabbedPane() {
               ActionMap actionMap = getActionMap();
               actionMap.put("SelectLeft", _leftNavigationAction);
               actionMap.put("SelectRight", _rightNavigationAction);
               InputMap inputMap = getInputMap(WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
               inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_LEFT,
                                             ActionEvent.ALT_MASK + ActionEvent.SHIFT_MASK), "SelectLeft");
               inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_RIGHT,
                                             ActionEvent.ALT_MASK + ActionEvent.SHIFT_MASK), "SelectRight");
     public static void main(String[] args) {
          TestBug4 test = new TestBug4("TestBug");
          test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          test.pack();
          test.setLocation(100, 70);
          test.setVisible(true);
          test.setDefaultFocus();
}
