GTK has a progress bar, but this is not my point.

I want to give feedback to the user during lengthy processing, as in my 
example, by updating a display element of the GUI. One choice is 
updating the contents of a text box. If this doesn't work then I am 
pretty sure that updating a progress bar wouldn't work either.
