I am working on a project and I want to set Mnemonic on buttons. But the problem is Mnemonic works on pairing key example (Alt+F) etc. But I want it to be on single key.
have look at KeyBindings,
then you can to attach any Key to the JButton
Here is one example code for your help, just Press C on the Keyboard :
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();
}
});
}
}
