package inter.frame;import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener;import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JOptionPane;public class MenuTest { /** * @param args */ JFrame frame; JMenuBar mb; JMenu m; JMenuItem mi1; JMenuItem mi2; public MenuTest() { initFrame(); initAction(); } public void initFrame() { frame = new JFrame(); mb = new JMenuBar(); m = new JMenu(学生查询); mi1 = new JMenuItem(确认); mi2 = new JMenuItem(取消); m.add(mi1); m.add(mi2); mb.add(m); frame.add(mb, BorderLayout.NORTH); frame.setSize(300, 300); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } public void initAction() { mi1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub System.out.println(click); JOptionPane.showMessageDialog(null, 你点击了确定按钮); } }); mi2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub JOptionPane.showMessageDialog(null, 你点击了取消按钮); } }); } public static void main(String[] args) { // TODO Auto-generated method stub new MenuTest(); }}
