-<a name="GtkOffscreenWindow.description"></a><h2>Description</h2>
-<p>
-GtkOffscreenWindow is strictly intended to be used for obtaining
-snapshots of widgets that are not part of a normal widget hierarchy.
-Since <a class="link" href="GtkOffscreenWindow.html" title="GtkOffscreenWindow"><span class="type">GtkOffscreenWindow</span></a> is a toplevel widget you cannot obtain
-snapshots of a full window with it since you cannot pack a toplevel
-widget in another toplevel.
-</p>
-<p>
-The idea is to take a widget and manually set the state of it,
-add it to a GtkOffscreenWindow and then retrieve the snapshot
-as a <a href="/usr/share/gtk-doc/html/cairo/cairo-cairo-surface-t.html#cairo-surface-t"><span class="type">cairo_surface_t</span></a> or <a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-The-GdkPixbuf-Structure.html#GdkPixbuf"><span class="type">GdkPixbuf</span></a>.
-</p>
-<p>
-GtkOffscreenWindow derives from <a class="link" href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a> only as an implementation
-detail. Applications should not use any API specific to <a class="link" href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a>
-to operate on this object. It should be treated as a <a class="link" href="GtkBin.html" title="GtkBin"><span class="type">GtkBin</span></a> that
-has no parent widget.
-</p>
-<p>
-When contained offscreen widgets are redrawn, GtkOffscreenWindow
-will emit a <a class="link" href="GtkWidget.html#GtkWidget-damage-event" title='The "damage-event" signal'><span class="type">"damage-event"</span></a> signal.
