Details:
Steps to reproduce:
1. Compile and run the attached testcase.
2. Hit enter over the textarea.
Expected results:
1. Programs prints the following to stdout
keyPressed, length now 0
keyTyped, length now 1
keyReleased, length now 1
Actual results:
1. Program prints the following to stdout
keyPressed, length now 0
keyTyped, length now 0
keyReleased, length now 1
Testcase:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class keyhandler extends JFrame {
private JTextArea a;
public static void main(String[] args) {
(new keyhandler()).show();
}
public keyhandler() {
this.a = new JTextArea(80, 25);
this.a.addKeyListener(new KeyHandler());
this.setContentPane(a);
this.setSize(new Dimension(400, 400));
}
private class KeyHandler implements KeyListener {
public void keyTyped(KeyEvent e) {
System.out.println("keyTyped, length now " +
keyhandler.this.a.getText().length());
}
public void keyPressed(KeyEvent e) {
System.out.println("keyPressed, length now " +
keyhandler.this.a.getText().length());
}
public void keyReleased(KeyEvent e) {
System.out.println("keyReleased, length now " +
keyhandler.this.a.getText().length());
}
}
}
Note that this bug seems to happen only with newline characters, typing
anything else won't trigger the bug.
