Name: pa48320 Date: 08/27/2002 Put the focus in a JTextArea and press Alt+Right, this types a "B". I tried to trace the origin of the problem and it seems to come from the type-ahead feature that generates a keyTyped event. This is a major problem for JDeveloper since those keys are used to navigate between editors. The following case is a trivial application that creates a JTextArea. Run the application and type Alt+Left, Alt+Right, Alt+PgUp, ... and you will see that characters are typed into the text. import java.awt.*; import javax.swing.*; public class Application1 { public static void main(String[] args) { JFrame frame = new JFrame(); frame.getContentPane().setLayout(new BorderLayout()); frame.getContentPane().add(new JTextArea()); frame.setBounds(100, 100, 200, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } } The problem is reproducable with JDK1.4.0 and 1.4.1 but was not present in previous releases. (Review ID: 163671) ====================================================================== I can reproduce the bug on Win2k. Do not see what it has to do with the text package. Take a look at the following example. -- import java.awt.*; import java.awt.event.*; public class Application1 { public static void main(String[] args) { Frame frame = new Frame(); Panel panel = new Panel(); frame.add(panel); panel.addKeyListener( new KeyAdapter() { public void keyPressed(KeyEvent e) { System.out.println("Application1.keyPressed "+e); } public void keyTyped(KeyEvent e) { System.out.println("Application1.keyTyped "+e); } public void keyReleased(KeyEvent e) { System.out.println("Application1.keyReleased " + e + "\n"); } } ); frame.setBounds(100, 100, 200, 200); frame.setVisible(true); } } -- When Alt+Right is pressed java.awt.event.KeyEvent[KEY_TYPED, keyCode=0, keyChar='B', keyLocation=KEY_LOCATION_UNKNOWN] get generated. That is why 'B' is typed in JTextArea. ###@###.### 2002-09-04
