Compile the enclosed code. Right-mouse-click on the text field then type 'A' or 'B'. In a native windows application, the corresponding menu item will be selected. In swing, the 'A' or 'B' appears in the text field. I have tried other examples where the component underneath the popup is a JTree. The key event goes to the JTree not the popup. The bug happens with both lightweight and heavtweight popups and reproduces in jdk 1.2.2

public class Test extends JFrame
{

    JTextField text = new JTextField();
    JPopupMenu menu = new JPopupMenu();
    
    Test()
    {
        JMenuItem item;
        
        this.setBounds(0, 0, 500, 500);
        text.setBounds(10, 10, 100, 25);
        getContentPane().add(text);
         getContentPane().setLayout(null);
        
        item = menu.add(new Action1());
        item.setMnemonic('A');
        item = menu.add(new Action2());
        item.setMnemonic('B');
        
        text.addMouseListener(new MyAdapter());
        
    }
    
    public static void main(String args[])
    {
        try
            {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
            }
        catch (Exception e)
            {
            e.printStackTrace();
            }
        
        
        Test test = new Test();
        test.validate();
        test.setVisible(true);
        
    }
    
    class Action1 extends AbstractAction
    {
        
        Action1()
        {
            
            super("AAction");
            
        }
        
        public void actionPerformed(ActionEvent event)
        {
            
            text.setText("AAction");
            
        }
    }
    
    class Action2 extends AbstractAction
    {
        
        Action2()
        {
            
            super("BAction");
            
        }
        
        public void actionPerformed(ActionEvent event)
        {
            
            text.setText("BAction");
            
        }
    }
    
    class MyAdapter extends MouseAdapter
    {
        
        public void mousePressed(MouseEvent event)
        {
            if (event.isMetaDown())
                {
                menu.show(text, event.getX(), event.getY());
                }
            
        }
        
    }

If I have some code like this inside a JPanel
-- begin --
final JPopupMenu jpm = new JPopupMenu( "Label" );
jpm.add( new JCheckBoxMenuItem( "Monday" ) );
jpm.add( new JCheckBoxMenuItem( "Tuesday" ) );
jpm.add( new JCheckBoxMenuItem( "Wednesday" ) );
jpm.add( new JCheckBoxMenuItem( "Thursday" ) );
jpm.add( new JCheckBoxMenuItem( "Friday" ) );
jpm.add( new JCheckBoxMenuItem( "Saturday" ) );
jpm.add( new JCheckBoxMenuItem( "Sunday" ) );

final JButton jb2 = new JButton(jpm.getLabel(), new ImageIcon("images/tdown.gif"));
jb2.setHorizontalTextPosition( jb2.LEADING );
jpm.setInvoker(this);
jb2.addActionListener( new AbstractAction()
{
public void actionPerformed( ActionEvent deed )
{
//SwingUtilities.invokeLater( new Runnable() { public void run() {
jpm.show( jb2, 0,0 ); // } } );
}
} );
add( jb2 );
-- end --

I cannot override any of the processKeyEvent methods, nor register keyboard actions, such that I can implement what
seems like appropriate behavior for VK_UP, VK_DOWN, SPACE,
TAB, and SHIFT_TAB.

All I want to do is have a menu that has check boxes in it
that can be driven by the keyboard, but the owner frame seems to get all keyboard/focus events.

Suggestions?
