GtkProgressBar

a widget which indicates progress visually.

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.

The #GtkProgressBar/#GtkProgress API in GTK 1.2 was bloated, needlessly complex
|
|
and hard to use properly. Therefore #GtkProgress has been deprecated
|
|
completely and the #GtkProgressBar API has been reduced to the following 10
|
|
functions: gtk_progress_bar_new(), gtk_progress_bar_pulse(),
|
|
gtk_progress_bar_set_text(), gtk_progress_bar_set_fraction(),
|
|
gtk_progress_bar_set_pulse_step(), gtk_progress_bar_set_orientation(),
|
|
gtk_progress_bar_get_text(), gtk_progress_bar_get_fraction(),
|
|
gtk_progress_bar_get_pulse_step(), gtk_progress_bar_get_orientation().
|
|
These have been grouped at the beginning of this section, followed by
|
|
a large chunk of deprecated 1.2 compatibility functions.
