<para>
The <link linkend="WnckWorkspace"><type>WnckWorkspace</type></link> represents what is called <ulink
url="http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#largedesks">virtual
desktops</ulink> in the <ulink
url="http://standards.freedesktop.org/wm-spec/wm-spec-latest.html">EWMH</ulink>.
A workspace is a virtualization of a <link linkend="WnckScreen"><type>WnckScreen</type></link><!-- -->: only one workspace
can be shown on a <link linkend="WnckScreen"><type>WnckScreen</type></link> at a time. It makes it possible, for example,
to put windows on different workspaces to organize them.
</para>
<para>
If the <link linkend="WnckWorkspace"><type>WnckWorkspace</type></link> size is bigger that the <link linkend="WnckScreen"><type>WnckScreen</type></link> size, the
workspace contains a viewport. Viewports are defined in the <ulink
url="http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#id2457064">large
desktops</ulink> section of the <ulink
url="http://standards.freedesktop.org/wm-spec/wm-spec-latest.html">EWMH</ulink>.
The notion of workspaces and viewports are quite similar, and generally both
are not used at the same time: there are generally either multiple
workspaces with no viewport, or one workspace with a viewport. libwnck
supports all situations, even multiple workspaces with viewports.
</para>
<para>
Workspaces are organized according to a layout set on the <link linkend="WnckScreen"><type>WnckScreen</type></link>. See
<link linkend="wnck-screen-try-set-workspace-layout"><function>wnck_screen_try_set_workspace_layout()</function></link> and
<link linkend="wnck-screen-release-workspace-layout"><function>wnck_screen_release_workspace_layout()</function></link> for more information about the
layout.
</para>

referenced or unreferenced.</para>
