 * @Short_description:
Prebuilt common menu/toolbar items and corresponding icons
 * @Title: Stock Items
 *
 * Stock items represent commonly-used menu or toolbar items such as
 * "Open" or "Exit". Each stock item is identified by a stock ID;
 * stock IDs are just strings, but macros such as #GTK_STOCK_OPEN are
 * provided to avoid typing mistakes in the strings.
 * Applications can register their own stock items in addition to those
 * built-in to GTK+.
 *
 * Each stock ID can be associated with a #GtkStockItem, which contains
 * the user-visible label, keyboard accelerator, and translation domain
 * of the menu or toolbar item; and/or with an icon stored in a
 * #GtkIconFactory. See <link
 * linkend="gtk3-Themeable-Stock-Images">GtkIconFactory</link> for
 * more information on stock icons. The connection between a
 * #GtkStockItem and stock icons is purely conventional (by virtue of
 * using the same stock ID); it's possible to register a stock item but
 * no icon, and vice versa. Stock icons may have a RTL variant which gets
 * used for right-to-left locales.
