#3838 — JTabbedPane with Keyevent

  To: comp.lang.java.gui
I have created a tabbedpane with 3 tabs (Tab1, Tab2, Tab3) . Mnemonic
(ALT-F) is assigned only to the Tab1.

If any of the component is selected inside the Tab2 or Tab3, it can
still traverse back to Tab1 on pressing key ALT-F.
But if any component is selected in the Tab1 itself, pressing ALT-F
will not take me back to Tab1. I have to somehow get the focus for
Tab1 too.


Here is  my code. Please respond to this.
Thank you.


Note:  I don’t  want to set Mnemonic to each Tab. Only one Mnemonic
should do my work.


import java.awt.BorderLayout;
import java.awt.event.KeyEvent;


import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;


public class myClass {


        public static void main(String args[]) throws Exception {


            JFrame frame = new JFrame();
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


             JTabbedPane tabbedPane = new JTabbedPane();


            JButton button1= new JButton("Button1");
            JButton button2= new JButton("Button2");
            JPanel panel1 = new JPanel();
            panel1.add(button1);
            panel1.add(button2);


            tabbedPane.addTab("Tab1", null, panel1, null);


            JLabel label = new JLabel("Check ");
            JCheckBox cbox = new JCheckBox("check me");
            JPanel panel = new JPanel();
            panel.add(label, null);
            panel.add(cbox);


            tabbedPane.addTab("Tab2", null, panel, null);


            JButton button2 = new JButton("Button");
            tabbedPane.addTab("Tab3", null, button2, null);


             int mnemonic = KeyEvent.VK_F;


tabbedPane.setMnemonicAt(tabbedPane.getSelectedIndex(), mnemonic);


            ChangeListener changeListener = new ChangeListener() {
                public void stateChanged(ChangeEvent changeEvent) {


                    JTabbedPane tab =
(JTabbedPane)changeEvent.getSource();
                    int index = tab.getSelectedIndex();


                    if(index==0)
                   tab.requestFocus();


                  }
              };
              tabbedPane.addChangeListener(changeListener);


            frame.add(tabbedPane, BorderLayout.CENTER);
            frame.setSize(400, 150);
            frame.setVisible(true);


        }

}

Do the other two methods for tab navigation (mouse or keyboard arrows) 
work?

Should this be button3?
