Specifying an element
with a progressbar
creates a new theme widget
which is an
x::w::progressbar
widget.
This is equivalent to invoking the factory's
create_progressbar() method.
The progressbar element's value
must be an id with a matching
type of a
layout which generates the initial layout
of the progress bar's contents.
This is typically a “grid” layout containing a centered
label widget.
An optional progressbar_config value
initializes
create_progressbar's
x::w::progressbar_config
parameter.
An optional config value sets the
progress bar's layout manager's optional configuration object.
