 * @accel_path: the unique path, used to identify the accelerator
 * @default_accelerator: the default key and modifier to trigger the callback linked to the entry
 * @menu_item_type: the type of the item which should be used for creation
 * @menu_item_label_text: text which should be shown in the menu
 * @menu_item_tooltip_text: optional tooltip of the item
 * @menu_item_icon_name: optional icon name which will be used to find a image for the item
 * @callback: the callback which will be triggered on activation. The callback has to return %TRUE
 *            to signal that the accelerator was activated and handled
 *
 * Replacement for the deprecated #GtkActionEntry.
 * The idea is to provide a fixed list of #XfceGtkActionEntrys:
 * - use xfce_gtk_translate_action_entries() once to translate the list
 * - use xfce_gtk_accel_map_add_entries() once to register the provided accelerators
 * - use xfce_gtk_get_action_entry_by_id() to find a single entry, e.g. by using a enumeration
 * - use xfce_gtk_*_new_from_action_entry() to create the specific menu- or tool-items from the entry
