Galera, estou com um problema ao capturar eventos de teclado.
Preciso navegar pela minha JTabbedPane com o ctrl + tab, por exemplo: o usuário mantém o ctrl pressionado e quando ele aperta o tab eu mudo a tab selecionada, já tentei muita coisa e não consegui.
Alguém pode me ajudar???
Obrigado!
Conforme você pode ver, Ctrl+Tab só funciona com JTabbedPane se o look & feel for Windows e se você estiver com um tab selecionado. Senão ele irá só mover o foco para o próximo controle (assim como ocorre em outros look & feels).
import javax.swing.*;
import java.awt.event.*;

class Tester {
public static void main(String[] args) {
final JFrame f = new JFrame();
final JTabbedPane tabbedPane = new JTabbedPane();
final JPanel panel1 = new JPanel(false),
panel2 = new JPanel(false),
panel3 = new JPanel(false),
panel4 = new JPanel(false),
panel5 = new JPanel(false),
panel6 = new JPanel(false),
panel7 = new JPanel(false),
panel8 = new JPanel(false),
panel9 = new JPanel(false);
// WindowListener for cosing progam.
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt) {
evt.getWindow().dispose();
System.exit(0);
}
});
tabbedPane.add("Panel 1", panel1);
tabbedPane.add("Panel 2", panel2);
tabbedPane.add("Panel 3", panel3);
tabbedPane.add("Panel 4", panel4);
tabbedPane.add("Panel 5", panel5);
tabbedPane.add("Panel 6", panel6);
tabbedPane.add("Panel 7", panel7);
tabbedPane.add("Panel 8", panel8);
tabbedPane.add("Panel 9", panel9);
f.getContentPane().add(tabbedPane, BorderLayout.CENTER);
//--------------------
// The remaining code simply allows for a change in the LaF....

JPanel LaFPanel = new JPanel();
final JButton windowsLaF = new JButton("Windows"),
motifLaF = new JButton("Motif"),
metalLaF = new JButton("Metal");
LaFPanel.add(windowsLaF);
LaFPanel.add(motifLaF);
LaFPanel.add(metalLaF);
ActionListener LaFListener = new ActionListener() {
public void actionPerformed(ActionEvent evt) {
Object src = evt.getSource();
try {
if(src == windowsLaF)
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
else if(src == motifLaF)
UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel");
else
UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
SwingUtilities.updateComponentTreeUI(f);
}
catch(Exception e) {
System.err.println("*** ERROR IN CHANGING LAF: " + e);
}
}
};
windowsLaF.addActionListener(LaFListener);
motifLaF.addActionListener(LaFListener);
metalLaF.addActionListener(LaFListener);
f.getContentPane().add(LaFPanel, BorderLayout.SOUTH);
f.setResizable(false);
f.setBounds(40, 40, 330, 200);
f.setVisible(true);
}
}
Eu pensei capturar o evento ao pressionar o ctrl + tab e apenas acionar um myTabbedPane.setSelectedIndex(tabNumber)…
O maior problema é capturar o ctrl + tab, não estou conseguindo…
Pronto fiz funcionar com qualquer look and feel 
Da uma olhada:
