JAVA JButton快捷键设置（组合键+单键）

2、若是设置类似“Ctrl+某键”的快捷键方式，JButton不可用，可以直接： 

jMenu.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_R , KeyEvent.CTRL_MASK))

3、单键设置

jButton.registerKeyboardAction(this, KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0),JComponent.WHEN_IN_FOCUSED_WINDOW);

以下单键例子：

按钮：

login = new JButton("登录"); login.registerKeyboardAction(this,     KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0),JComponent.WHEN_IN_FOCUSED_WINDOW); exit = new JButton("关闭"); exit.registerKeyboardAction(this,     KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE,0),JComponent.WHEN_IN_FOCUSED_WINDOW); login.addActionListener(this); exit.addActionListener(this);

事件：

public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub  Object obj = e.getSource();        if(obj == login)   { 

  }                   else if(obj == exit){               System.exit(0);                 }else{                }

}
