- * SECTION:gtkiconfactory
- * @Short_description: Manipulating stock icons
- * @Title: Themeable Stock Images
- *
- * 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.
- *
- * # GtkIconFactory as GtkBuildable # {#GtkIconFactory-BUILDER-UI}
- *
- * GtkIconFactory supports a custom <sources> element, which can contain
- * multiple <source> elements. The following attributes are allowed:
- *
- * - stock-id
- *
- * The stock id of the source, a string. This attribute is
- * mandatory
- *
- * - filename
- *
- * The filename of the source, a string. This attribute is
- * optional
- *
- * - icon-name
- *
- * The icon name for the source, a string. This attribute is
- * optional.
- *
- * - size
- *
- * Size of the icon, a #GtkIconSize enum value. This attribute is
- * optional.
- *
- * - direction
- *
- * Direction of the source, a #GtkTextDirection enum value. This
- * attribute is optional.
- *
- * - state
- *
- * State of the source, a #GtkStateType enum value. This
- * attribute is optional.
- *
- *
- * ## A #GtkIconFactory UI definition fragment. ##
- *

- * <object class="GtkIconFactory" id="iconfactory1">
