Hi,

I'm trying to have System.in point to a JTextArea instead of the command
prompt. To accomplish this, i've written my own InputStream class. The class
works partly: System.in.read() does return character typed in the JTextArea,
but when i use BufferedReader.readLine(), the method never returns
(System.in.read() DOES return '\n' characters). I know JBuilder does exactly
the same thing with success. Any help is appreciated!

  class Pl0InputStream extends InputStream {
    /** JTextArea. */
    private JTextArea fTextArea;

    /** Typed keys. */
    private Stack fStack = new Stack();

    /**
     * Constructor.
     */
    public Pl0InputStream(JTextArea textArea) {
      fTextArea = textArea;
      fTextArea.addKeyListener(new KeyAdapter() {
        public void keyTyped(KeyEvent e) {
          synchronized(this) {
            fStack.push(new Character(e.getKeyChar()));
          }
        }
      });
    }

    public int read() {
      while (fStack.empty()) {
        try {
          Thread.sleep(250);
        } catch (InterruptedException ex) {
          ex.printStackTrace();
        }
      }
      return ((Character)fStack.pop()).charValue();
    }
  }
