It provides a visual clue that processing is underway. The <see cref="T:Gtk.ProgressBar" /> 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 <see cref="T:Gtk.ProgressBar" /> 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 set <see cref="P:Gtk.ProgressBar.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 <see cref="T:Gtk.ProgressBar" /> 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 <see cref="M:Gtk.ProgressBar.Pulse()" /> perodically to update the progress bar.</para> <para>There is quite a bit of flexibility provided to control the appearance of the <see cref="T:Gtk.ProgressBar" />. 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.</para> </remarks> </Docs> <Base> <BaseTypeName>Gtk.Progress</BaseTypeName> </Base> <Interfaces> <Interface> <InterfaceName>Atk.Implementor</InterfaceName> </Interface> <Interface> <InterfaceName>GLib.IWrapper</InterfaceName> </Interface> <Interface> <InterfaceName>GLib.IWrapper</InterfaceName> </Interface> <Interface> <InterfaceName>System.IDisposable</InterfaceName> </Interface> </Interfaces> <Attributes /> <Members> <Member MemberName="Pulse"> <MemberSignature Language="C#" Value="public void Pulse ();" /> <MemberType>Method</MemberType> <ReturnValue> <ReturnType>System.Void</ReturnType> </ReturnValue> <Parameters /> <Docs> <summary>Indicates an unknown amount of progress has been made</summary> <remarks>Indicates that some progress has been made, but you don't know how much.
