.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. 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
gtkProgressBarSetFraction
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 gtkProgressBarPulse
perodically
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.
PLEASE NOTE: 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: gtkProgressBarNew
, gtkProgressBarPulse
,
gtkProgressBarSetText
, gtkProgressBarSetFraction
,
gtkProgressBarSetPulseStep
, gtkProgressBarSetOrientation
,
gtkProgressBarGetText
, gtkProgressBarGetFraction
,
gtkProgressBarGetPulseStep
, gtkProgressBarGetOrientation
.
These have been grouped at the beginning of this section, followed by
a large chunk of deprecated 1.2 compatibility functions.gtkProgressBar
is the result of collapsing the constructors of GtkProgressBar
(gtkProgressBarNew
, gtkProgressBarNewWithAdjustment
) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.GtkProgressBarOrientation

has the side-effect that the progressbar requests
only enough space to display the ellipsis "...". Another means to set a
progressbar's width is gtkWidgetSetSizeRequest
