Activity Indicator

Is there a standard way of displaying that a window is busy processing
some data which will allow the user to cancel the operation? For
example, I'm downloading a chunk of data of unknown length. I can't use
a progress bar / dialog since I don't know what percentage is complete?

I have a modified ProgressDialog goodie at:

http://www.dolphinharbor.org/dh/projects/goodies/sprayProgress.html

This automatically ticks the progress bar at a set interval and loops back
to the start if the operation takes longer than expected. It could be
improved by showing some kind of icon animation instead of the progress bar.

Thank you! What I've done instead is to create a new view based on the
CountDown Progress Dialog Example and use that instead. I display the
amount of data downloaded as a string.
