Re: Possible easy diagnostic outputting from multiple threads to the one text frame

Here's an example. This class is, I believe, thread-safe,
although quite simple.

class TextAreaHandler extends Handler {

    private final JTextArea view;

    public TextAreaHandler( JTextArea view )
    {
       this.view = view;
    }

    @Override
    public void publish( LogRecord record )
    {
       view.append( record.getMessage() );
       view.append( '\n' );
    }

    @Override
    public void flush()
    {
       // no-op
    }

    @Override
    public void close()
    {
       // possibly dispose the top-level window here
    }

}
