public class JTextAreaWriter

extends java.io.Writer

A implementation of the java.io.Writer class which provides writing to a JTextArea via a stream.

Note: There appears to be bug in the Macintosh implementation of the JDK 1.1 where a PrintWriter writing to this class will not include the correct line feeds for display in a JTextArea. There is a simple test of the "java.version" system property which, if it starts with the String "1.1" will cause newlines to be written each time the buffer is flushed.
