    <summary>A widget which indicates progress visually.</summary>
    <remarks>
      <para>The <see cref="T:Gtk.ProgressBar" /> is typically used to display the progress of a long running operation.
				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>

        <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.
					This causes the <see cref="T:Gtk.ProgressBar" /> to enter "activity mode," where a block bounces back and forth.
					Each call to <see cref="M:Gtk.ProgressBar.Pulse()" /> causes the block to move by a little bit (the amount of movement per pulse is determined by <see cref="P:Gtk.ProgressBar.PulseStep" />).</remarks>
