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
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.
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()
periodically to update the progress bar.
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.
