      Description



      Name: jk109818 Date: 09/10/2002


      FULL PRODUCT VERSION :
      java version "1.4.0_01"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
      Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)

      FULL OPERATING SYSTEM VERSION :
      Microsoft Windows 2000 [ÃM-^E^T±M-^HM-^P 5.00.2195]

      ADDITIONAL OPERATING SYSTEMS :
      All, this is OS/independent issue



      A DESCRIPTION OF THE PROBLEM :
      Any non-English letter (Russian, Greek, ...),
      don't work as button mnemonic.

      Applyies to keyboards which have 1:1 correspondance between
      locale and English keys.

      The problem is that using two different methods
      setMnemonic(VK_<Latin>) & setMnemonic('<Locale char>')
      we get different, but both unworkable results.



      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. compile & run
      2. Press Alt+G
      3. Press Alt+K
      4. Press Alt+R

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      Expected:
      1. All button have underlined items on it
      2. output:
      English Mnemonic of Russian Label works
      Russian Mnemonic of Russian Label works
      Solely English Mnemonic works

      Actual:
      1. First button has no underlined symbol on it
      2. output:
      English Mnemonic of Russian Label works
      Solely English Mnemonic works


      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      import java.awt.*;
      import java.awt.event.*;
      import javax.swing.*;

      public class MnemonicTest {

        public static void main(String[] args){
          JFrame frame = new JFrame("Mnemonic Test");
          Container contentPane = frame.getContentPane();
          JButton bad1 = new JButton("\u041F\u043B\u043E\u0445\u0430\u044F"); // "Bad"
          JButton bad2 = new JButton("\u041F\u043B\u043E\u0445\u0430\u044F"); // "Bad"
          JButton right = new JButton("Right");
          right.setMnemonic(KeyEvent.VK_R);

      // Neigther of the following work correctly:
      // 1.
          bad1.setMnemonic(KeyEvent.VK_G);
          // Pressing Alt+Î generates VK_G keycode
          // Alt+G works, but Î doesn't get underlined
      // 2.
          bad2.setMnemonic('\u043B');
          // Passing the character itself
          // Symbol gets underlined, but Alt+K (\u043B is under K) doesn't work

          bad1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e){
              System.out.println("English Mnemonic of Russian Label works");
            }
          });
          bad2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e){
              System.out.println("Russian Mnemonic of Russian Label works");
            }
          });
          right.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e){
              System.out.println("Solely English Mnemonic works");
            }
          });

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

          contentPane.setLayout(new FlowLayout());
          contentPane.add(bad1);
          contentPane.add(bad2);
          contentPane.add(right);
          frame.pack();
          frame.setVisible(true);
        }

      }

      ---------- END SOURCE ----------

      CUSTOMER WORKAROUND :
      add
          bad1.setDisplayedMnemonicIndex(0);
      before line 17 in the code,
      the leftmost button works on Alt+G and gets underlined.

      Please, add this RFE and mark it fixed.
      Or change HOWTOs, document this possibility in
      AbstractButton, JLabel classes.
      There's only a silly example for "Save As..." there.
