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. 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() 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. 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. The #GtkProgressBar-struct struct contains private data only, and should be accessed using the functions below. Creates a new #GtkProgressBar. @void: @Returns: a #GtkProgressBar. @pbar: @pbar: @text: @pbar: @fraction: @pbar: @fraction: @pbar: @orientation: @pbar: @mode: An enumeration representing possible orientations and growth directions for the visible progress bar. @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. @pbar: @Returns: @pbar: @Returns: @pbar: @Returns: @pbar: @Returns: @pbar: @Returns: An enumeration representing the styles for drawing the progress bar. @GTK_PROGRESS_CONTINUOUS: The progress bar grows in a smooth, continuous manner. @GTK_PROGRESS_DISCRETE: The progress bar grows in discrete, visible blocks.
