设置快捷键

Java code

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MnemonicButton implements ActionListener{
   public MnemonicButton(){
   JFrame f=new JFrame("MnemonicButton");
   Container contentPane=f.getContentPane();
   JButton b=new JButton("Open new window");
   b.setMnemonic('o');
   b.addActionListener(this);
   contentPane.add(b);
   f.pack();
   f.show();
   f.addWindowListener(new WindowAdapter(){
   public void windowClosing(WindowEvent e){
   System.exit(0);
   }
   });
   }

   public void actionPerformed(ActionEvent e){
   JFrame newF=new JFrame("新窗口");
   JLabel label=new JLabel("这是新窗口");
   label.setHorizontalAlignment(JLabel.CENTER);
   newF.getContentPane().add(label);
   newF.setSize(100,100);
   newF.show();
   }
   
public static void main(String[] args) {
// TODO Auto-generated method stub
new MnemonicButton();

}

}

探讨

Java codeJB.setMnemonic(java.awt.event.KeyEvent.VK_F1);



好像不能直接写 JB.setMnemonic(“F1”); 注意！
