The "fill level" is probably best described by its most prominent use case,
which is an indicator for the amount of pre-buffering in a streaming media
player. In that use case, the value of the range would indicate the current
play position, and the fill level would be the position up to which the
file/stream has been downloaded.
</p><p>
This amount of prebuffering can be displayed on the range's trough and is
themeable separately from the trough. To enable fill level display, use
<code class="methodname"><a class="link" href="class-gtkrange.html#method-gtkrange--set-show-fill-level" title="gtk.Range.set_show_fill_level">gtk.Range.set_show_fill_level</a></code>().
The range defaults to not showing the fill level.
</p><p>
Additionally, it's possible to restrict the range's slider position to values
which are smaller than the fill level. This is controller by
<code class="methodname"><a class="link" href="class-gtkrange.html#method-gtkrange--set-restrict-to-fill-level" title="gtk.Range.set_restrict_to_fill_level">gtk.Range.set_restrict_to_fill_level</a></code>()

returning <code class="literal">False</code>, it can pass the event to other
handlers until the default GTK+ handler is reached.</p><p>The value parameter is unrounded. An application that overrides
