<title>Description</title>
<para>
<type>GnomeDockBand</type> is a widget implementing a "dock band", i.e. a
horizontal or vertical stripe containing dockable widgets.
</para>

<para>
The application programmer does not normally need to use
<type>GnomeDockBand</type>s directly; they are mostly used by the
<type>GnomeDock</type> widget to implement its functionality.  For an
explanation of the way dock bands are used within a dock, check out
the documentation for the <type>GnomeDock</type> widget.
