The idea is to take a widget and manually set the state of it,

add it to a <a class="link" href="GtkOffscreenWindow.html" title="GtkOffscreenWindow">GtkOffscreenWindow</a> and then retrieve the snapshot

as a <a href="http://library.gnome.org/devel/gdk3/gdk-Bitmaps-and-Pixmaps.html#GdkPixmap">GdkPixmap</a> or <a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-The-GdkPixbuf-Structure.html#GdkPixbuf">GdkPixbuf</a>.

as a <a href="../gdk2/gdk2-Bitmaps-and-Pixmaps.html#GdkPixmap">GdkPixmap</a> or <a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-The-GdkPixbuf-Structure.html#GdkPixbuf">GdkPixbuf</a>.

<a class="link" href="GtkOffscreenWindow.html" title="GtkOffscreenWindow">GtkOffscreenWindow</a> derives from <a class="link" href="GtkWindow.html" title="GtkWindow">GtkWindow</a> only as an implementation
