updating on the fly

If I've understood you correctly, you want a
text box that continually checks the status of
some string or file, and writes that data out
to it's window.

To do this, I would suggest that you make the
text box run in it's own thread. To do this,
create a TextBox class that implements runnable.
in the final line of the constructor write
new Thread(this).start().

Then, in the run() method of the class,
create an infinite while loop (while true)
that continaully reads the String or file,
and writes that data to the textBox window.

If none of this makes sense, look up the
Thread and runnable API's on the Java API
webSite. Hopefully they can help you out.
