import java.awt.*;import java.awt.event.*;import javax.swing.*;import javax.swing.Action;public class ButtonExample{ private Jframe frame; private JButton button; private void displayGUI() { frame = new Jframe("Button Mnemonic Example"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); JPanel contentPane = new JPanel(); Action buttonAction = new ButtonAction("CLICK ME" , "This is a Click Me JButton"); button = new JButton(buttonAction); button.getInputMap().put(KeyStroke.getKeyStroke('c'), "Click Me Button"); button.getActionMap().put("Click Me Button", buttonAction); contentPane.add(button); frame.setContentPane(contentPane); frame.pack(); frame.setLocationByPlatform(true); frame.setVisible(true); } class ButtonAction extends AbstractAction { public ButtonAction(String text, String desc) { super(text); putValue(SHORT_DEscriptION, desc); } @Override public void actionPerformed(ActionEvent ae) { JOptionPane.showMessageDialog(frame, "BINGO, you SAW me."); } } public static void main(String... args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new ButtonExample().displayGUI(); } }); }}
