ReverseBar¶

ReverseBar draws a fill bar whose marker grows right to left.

It is Bar with the fill direction reversed: same arguments, same behavior, marker growing from the right edge instead.

class progressbar.widgets.ReverseBar(marker='#', left='|', right='|', fill=' ', fill_left=False, **kwargs)[source]

Bases: Bar

A bar which has a marker that goes from right to left.

Create a Bar that fills from the right by default.

See Bar.__init__ for parameter meaning. fill_left defaults to False here instead of True.

Example¶

"""``ReverseBar`` draws a fill bar whose marker grows right to left.

Reach for it to visually contrast with a normal ``Bar`` -- for example a
pair of gauges that meet in the middle -- or any layout that reads
right-to-left. Everything else about it matches ``Bar``.
