<!-- ##### 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 longrunning operation. It provides a visual clue that processingis underway. The #GtkProgressBar can be used in two differentmodes: 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 itsprogress, it can use the #GtkProgressBar in percentage mode and the usersees a growing bar indicating the percentage of the work that hasbeen completed. In this mode, the application is required to callgtk_progress_bar_set_fraction() periodically to update the progress bar.</para><para>When an application has no accurate way of knowing the amount of workto 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() perodicallyto update the progress bar.</para><para>There is quite a bit of flexibility provided to control the appearanceof the #GtkProgressBar. Functions are provided to control the orientation of the bar, optional text can be displayed along withthe bar, and the step size used in activity mode can be set.</para><note><para>The #GtkProgressBar/#GtkProgress API in GTK 1.2 was bloated, needlessly complexand hard to use properly. Therefore #GtkProgress has been deprecatedcompletely and the #GtkProgressBar API has been reduced to the following 10functions: 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.</para></note><!-- ##### SECTION See_Also ##### --><para></para><!-- ##### SECTION Stability_Level ##### --><!-- ##### STRUCT GtkProgressBar ##### --><para>The #GtkProgressBar-struct struct contains private data only, and should be accessed using the functions below.</para><!-- ##### ARG GtkProgressBar:activity-blocks ##### --><para></para><!-- ##### ARG GtkProgressBar:activity-step ##### --><para></para><!-- ##### ARG GtkProgressBar:adjustment ##### --><para></para><!-- ##### ARG GtkProgressBar:bar-style ##### --><para></para><!-- ##### ARG GtkProgressBar:discrete-blocks ##### --><para></para><!-- ##### ARG GtkProgressBar:ellipsize ##### --><para></para><!-- ##### ARG GtkProgressBar:fraction ##### --><para></para><!-- ##### ARG GtkProgressBar:orientation ##### --><para></para><!-- ##### ARG GtkProgressBar:pulse-step ##### --><para></para><!-- ##### ARG GtkProgressBar:text ##### --><para></para><!-- ##### FUNCTION gtk_progress_bar_new ##### --><para>Creates a new #GtkProgressBar.</para>@Returns: a #GtkProgressBar.<!-- ##### FUNCTION gtk_progress_bar_pulse ##### --><para></para>@pbar: <!-- ##### FUNCTION gtk_progress_bar_set_text ##### --><para></para>@pbar: @text: <!-- ##### FUNCTION gtk_progress_bar_set_fraction ##### --><para></para>@pbar: @fraction: <!-- ##### FUNCTION gtk_progress_bar_set_pulse_step ##### --><para></para>@pbar: @fraction: <!-- ##### FUNCTION gtk_progress_bar_set_orientation ##### --><para></para>@pbar: @orientation: <!-- ##### FUNCTION gtk_progress_bar_set_ellipsize ##### --><para></para>@pbar: @mode: <!-- ##### ENUM GtkProgressBarOrientation ##### --><para>An enumeration representing possible orientations and growthdirections for the visible progress bar.</para>@GTK_PROGRESS_LEFT_TO_RIGHT: A horizontal progress bar growing from left to right.@GTK_PROGRESS_RIGHT_TO_LEFT: A horizontal progress bar growing from right to left.@GTK_PROGRESS_BOTTOM_TO_TOP: A vertical progress bar growing from bottom to top.@GTK_PROGRESS_TOP_TO_BOTTOM: A vertical progress bar growing from top to bottom.<!-- ##### FUNCTION gtk_progress_bar_get_text ##### --><para></para>@pbar: @Returns: <!-- ##### FUNCTION gtk_progress_bar_get_fraction ##### --><para></para>@pbar: @Returns: <!-- ##### FUNCTION gtk_progress_bar_get_pulse_step ##### --><para></para>@pbar: @Returns: <!-- ##### FUNCTION gtk_progress_bar_get_orientation ##### --><para></para>@pbar: @Returns: <!-- ##### FUNCTION gtk_progress_bar_get_ellipsize ##### --><para></para>@pbar: @Returns: <!-- ##### FUNCTION gtk_progress_bar_new_with_adjustment ##### --><para>Creates a new #GtkProgressBar with an associated #GtkAdjustment.</para>@adjustment: a #GtkAdjustment.@Returns: a #GtkProgressBar.<!-- ##### FUNCTION gtk_progress_bar_set_bar_style ##### --><para>Sets the style of the #GtkProgressBar.
