javax.swing.JLabel: displayedMnemonic don't respect an disabled Component

Name: skT88420 Date: 06/09/99


- bind a JTextField to a JLabel via label.setLabelFor(textField)
- set a valid mnemonic on the label using label.setDisplayedMnemonic(..)
- disable the Textfield
- activate the Mnemonic of the label
- the focus is set on the Textfield, the cursor is blinking,
  and deleting can be performed --> BUG

Here is a small test case:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class LabelBug
{
  public static void main(String[] argv)
  {
    JLabel header = new JLabel("Press <ALT-E>: you can navigate and delete");

    JTextField textField = new JTextField("This is the text to be removed", 20);
    textField.setEnabled(false);

    JLabel label = new JLabel("Enter your text here");
    label.setLabelFor(textField);
    label.setDisplayedMnemonic('e');

    JButton button = new JButton("Press");
    button.setMnemonic('p');

    JFrame frame = new JFrame("LabelFor Bug");
    frame.getContentPane().setLayout(new BorderLayout());
    frame.getContentPane().add(header, BorderLayout.NORTH);
    frame.getContentPane().add(label, BorderLayout.WEST);
    frame.getContentPane().add(textField, BorderLayout.CENTER);
    frame.getContentPane().add(button, BorderLayout.SOUTH);

    frame.addWindowListener(new WindowAdapter()
      {
        public void windowClosing(WindowEvent E)
        {
          System.exit(0);
        }
      });

    frame.pack();
    frame.show();

    // -- yes, this is not thread safe, but an initial focus is needed --
    button.requestFocus();
  }
}

Look at the source code of javax.swing.plaf.basic.BasicLabelUI:
inner classes PressAction und ReleaseAction don't respect if the
target component is disabled.
