<title>Use named icons</title>
<formalpara>
<title>Why</title>
<para>
Named icons automatically adapt to theme changes, giving your
application a much more integrated appearance.
</para>
</formalpara>
<para>
Since GTK+ 2.6, named icons can be used for window icons (see
gtk_window_set_icon_name()) and images (see gtk_image_set_icon_name()).
In GTK+ 2.8, you can also use named icons for drag-and-drop (see
gtk_drag_source_set_icon_name()) and in treeview cells (see the
<link linkend="GtkCellRendererPixbuf--icon-name">icon_name</link>
property of #GtkCellRendererPixbuf).
