System.out in GUI, or something similar

Wait a second; I've got something for that. <dig dig shuffle shuffle> Ah!

Here it is:public class TextAreaOutputStream extends OutputStream {

private static final int TABSTOP= 4;

private static final int SIZE= 0x8000;

private static final boolean WORDWRAP= true;

private static final int ROWS= 24;

private static final int COLS= 80;

protected JTextArea ta;

public TextAreaOutputStream() { this(new JTextArea(ROWS, COLS)); }

public TextAreaOutputStream(JTextArea ta) { this(ta, TABSTOP, WORDWRAP); }

public TextAreaOutputStream(JTextArea ta, int tabstop, boolean wordwrap) {

this.ta= ta;

initialize(tabstop, wordwrap, false);

}

private void initialize(int tabstop, boolean wordwrap, boolean editable) {

ta.setTabSize(tabstop);

ta.setWrapStyleWord(wordwrap);

ta.setEditable(editable);

}

protected void append(String text) {

int lt= text.length();

synchronized(ta) {

if (lt >= SIZE) {

ta.setText(text);

return;

}

String buf= ta.getText();

int i= 0;

lt+= buf.length();

for (int j= 0; lt-i >= SIZE; i= j+1)

if ((j= buf.indexOf('\n', i)) < 0)

break;

if (lt-i >= SIZE)

ta.setText(buf= text);

else

ta.setText(buf= buf.substring(i)+text);

ta.setCaretPosition(buf.length());

}

}

public JTextArea getJTextArea() { return ta; }

public void write(int b) { append(""+((char)b)); }

public void write(byte b[]) { write(b, 0, b.length); }

public void write(byte b[], int ofs, int len) { append(new String(b, ofs, len)); }

}

Simply hook this up to a System.out or Sytem.err stream and you're in business.

kind regards,

Jos
