Methods inherited from class ProgressIndicator

class ProgressIndicator
A progress indicator intended for terminal output (relies on ^H).
Indicator style, given as constructor argument, can be
0: percentage; 1: bar; or 2: both. Default is 0.

If using styles 1 or 2, an optional width argument
for the bar portion can also be given (default 60).

Example usage:
# First emit whatever prefaces the indicator, if desired
print " status:",
# Create a new indicator
p = ProgressIndicator(2)
# With each iteration through a task, or as often as you want,
# call updateProgress(), passing 2 numbers: amount completed,
# and total amount to do.
limit = 300000
for i in range(limit):
    p.updateProgress(i, limit)
