+ * SECTION:gtkiconfactory
+ * @Short_description: Manipulating stock icons
+ * @Title: Themeable Stock Images
+ *
+ * Browse the available stock icons in the list of stock IDs found <link
+ * linkend="gtk-Stock-Items">here</link>. You can also use
+ * the <application>gtk-demo</application> application for this purpose.
+ *
+ * An icon factory manages a collection of #GtkIconSet; a #GtkIconSet manages a
+ * set of variants of a particular icon (i.e. a #GtkIconSet contains variants for
+ * different sizes and widget states). Icons in an icon factory are named by a
+ * stock ID, which is a simple string identifying the icon. Each #GtkStyle has a
+ * list of #GtkIconFactory derived from the current theme; those icon factories
+ * are consulted first when searching for an icon. If the theme doesn't set a
+ * particular icon, GTK+ looks for the icon in a list of default icon factories,
+ * maintained by gtk_icon_factory_add_default() and
+ * gtk_icon_factory_remove_default(). Applications with icons should add a default
+ * icon factory with their icons, which will allow themes to override the icons
+ * for the application.
+ *
+ * To display an icon, always use gtk_style_lookup_icon_set() on the widget that
+ * will display the icon, or the convenience function
+ * gtk_widget_render_icon(). These functions take the theme into account when
+ * looking up the icon to use for a given stock ID.
