<!-- ##### SECTION Title ##### -->
GtkProgressBar
<!-- ##### SECTION Short_Description ##### -->
A widget which indicates progress visually
<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkProgressBar is typically used to display the progress of a long
running operation. It provides a visual clue that processing
is underway. The #GtkProgressBar can be used in two different
modes: percentage mode and activity mode.
</para>
<para>
When an application can determine how much work needs to take place
(e.g. read a fixed number of bytes from a file) and can monitor its
progress, it can use the #GtkProgressBar in percentage mode and the user
sees a growing bar indicating the percentage of the work that has
been completed. In this mode, the application is required to call
gtk_progress_bar_set_fraction() periodically to update the progress bar.
</para>
<para>
When an application has no accurate way of knowing the amount of work
to do, it can use the #GtkProgressBar in activity mode, which shows activity
by a block moving back and forth within the progress area. In this mode,
the application is required to call gtk_progress_bar_pulse() perodically
to update the progress bar.
</para>
<para>
There is quite a bit of flexibility provided to control the appearance
of the #GtkProgressBar. Functions are provided to control the
orientation of the bar, optional text can be displayed along with
the bar, and the step size used in activity mode can be set.
