Sorry this went so long without a reply.
> Is there a way to ask Java would the right keyboard shortcut should
be?
Yes. Try:
int modifier = Toolkit.getDefaultToolkit().getMenuShortcutKeyMaskEx()
A sample usage is below.
import javax.swing.*;
import javax.swing.border.EmptyBorder;
import java.awt.*;
import java.awt.event.KeyEvent;
public class ShortcutDemo extends JFrame {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
ShortcutDemo d = new ShortcutDemo();
d.pack();
d.setVisible(true);
}
});
}
public ShortcutDemo() {
JMenuBar menuBar = new JMenuBar();
JMenu editMenu = new JMenu("Edit");
JMenuItem copyMenuItem = new JMenuItem("Copy");
copyMenuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C,
Toolkit.getDefaultToolkit().getMenuShortcutKeyMaskEx()));
menuBar.add(editMenu);
editMenu.add(copyMenuItem);
setJMenuBar(menuBar);
JLabel label = new JLabel("Placeholder Label");
label.setBorder(new EmptyBorder(20,20,20,20));
getContentPane().add(label);
}
}
Does this answer your question?
Regards,
- Jeremy
