JTextField和F10键-如何删除键绑定？

Question

I'm trying to remove F10 button key binding from JTextField , but nothing is working below:

getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.KEY_PRESSED), "none");
getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.KEY_TYPED), "none");
getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.KEY_RELEASED), "none");

Actually, I want to control popup menu - show/hide, but F10 not working correctly - it is performing some other actions. If I switch for example to F11 , everything works fine.

As I know - Shift + F10 shows popup on various platforms.

Answer 1

KeyStroke.getKeyStroke(int, int) isn't used to get the KeyStroke for a press or release event, it is used to apply a modifier to the KeyStroke in the form of KeyEvent.SHIFT_DOWN_MASK and/or KeyEvent.CTRL_DOWN_MASK and/or KeyEvent.ALT_DOWN_MASK and/or KeyEvent.ALT_GRAPH_DOWN_MASK and/or KeyEvent.META_DOWN_MASK ...

Instead of getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.KEY_PRESSED), "none"); you should be using getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, 0), "none");

When I use the following, I can get the key action to trigger when the field is focused...

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.KeyEvent;
import javax.swing.AbstractAction;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JPopupMenu;
import javax.swing.JTextField;
import javax.swing.KeyStroke;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class TestTextFieldKeyStroke {

    public static void main(String[] args) {
        new TestTextFieldKeyStroke();
    }

    public TestTextFieldKeyStroke() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame("Testing");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new TestPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }
        });
    }

    public class TestPane extends JPanel {

        public TestPane() {
            JTextField field = new JTextField(20);
            add(field);
            JPopupMenu pop = new JPopupMenu();

            field.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, 0), "happy");
            field.getActionMap().put("happy", new AbstractAction() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    System.out.println("Happy");
                }
            });

        }
    }
}

Updated with popup

I'm still missing something here, based on the previous example, if I do something like...

final JTextField field = new JTextField(20);
add(field);
JPopupMenu pop = new JPopupMenu();
pop.add(new JLabel("Hello"));
field.setComponentPopupMenu(pop);

field.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, 0), "happy");
field.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.CTRL_DOWN_MASK), "happy");
field.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.ALT_DOWN_MASK), "happy");
field.getActionMap().put("happy", new AbstractAction() {
    @Override
    public void actionPerformed(ActionEvent e) {
        JPopupMenu popup = field.getComponentPopupMenu();
        popup.show(field, 0, field.getHeight());
    }
});

I can get it to show the JPopupMenu

Answer 2

I have tried this and it's working:

getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, 0), "doNothing");
getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.SHIFT_DOWN_MASK), "doNothing");
getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_F10, KeyEvent.CTRL_DOWN_MASK), "doNothing");

        getActionMap().put("doNothing", new AbstractAction() {
            @Override
            public void actionPerformed(ActionEvent e) {
                //Do nothing
            }
        });

Now F10 , Shift + F10 and Ctrl + F10 events are removed. But if I skip getActionMap().put("doNothing", new AbstractAction() {}) , then key bindings above not working.., but it seems that somewhere some action is still attached - cursor is changing (from Cursor.TEXT_CURSOR to Cursor.MOVE_CURSOR and again backs to Cursor.TEXT_CURSOR ) when I press on those buttons (should do nothing). I've tried textField.getActionMap().size() but it return 0. So I suppose action is attached to some other component. Is it possible to find out it?
