A JProgressBar is very well suited if you have a task where the
duration, or the criteria for finishing a task is known.  What about
those times where the completion of a task isn't so clearly known?

I'm translating a "busybar" from a couple of other languages I work
with over to Java.  So instead of building a left to right stack of
rectangles to the end of the dialog (as in JProgressBar), I have two
rectangles that bounce back and forth in "pong"-like fashion until the
thread dies.  IMHO, this is better feedback for the users than simply
waiting on an hourglass cursor (again, only when the length of the task
completion is unknown); they see the application is performing an
action and they can relate to that.  What I have in these other
languages is pretty elegant.  I grew frustrated with seeing all the
hacked flavors of progressbars out there, rife with code smells and
bugs, and decided to emulate one instead.  It involves drawing two
contrasting rectangles (and one the same color as the background to
'erase' tracks) and using some remainder division and a timer to
control the scrolling back and forth.
