swing快捷键

JButton btnNewButton = new JButton("New button");
  btnNewButton.registerKeyboardAction(new ActionListener() {
   public void actionPerformed(ActionEvent e) {
    JOptionPane.showMessageDialog(null, "sdfsaf");
   }
  }, KeyStroke.getKeyStroke(KeyEvent.VK_F6,0),
    JComponent.WHEN_IN_FOCUSED_WINDOW);

红色处如果不使用其他组合键就用0代替,需要组合键时直接使用修饰符(例如KeyEvent.CTRL_DOWN_MASK)替换0
