-- @GMenuModel@ represents the contents of a menu — an ordered list of
-- menu items. The items are associated with actions, which can be
-- activated through them. Items can be grouped in sections, and may
-- have submenus associated with them. Both items and sections usually
-- have some representation data, such as labels or icons. The type of
-- the associated action (ie whether it is stateful, and what kind of
-- state it has) can influence the representation of the item.
-- 
-- The conceptual model of menus in @GMenuModel@ is hierarchical:
-- sections and submenus are again represented by @GMenuModel@s.
-- Menus themselves do not define their own roles. Rather, the role
-- of a particular @GMenuModel@ is defined by the item that references
-- it (or, in the case of the ‘root’ menu, is defined by the context
-- in which it is used).
-- 
-- As an example, consider the visible portions of this menu:
-- 
-- == An example menu
-- 
-- <<http://developer.gnome.org/gio/stable/menu-example.png>>
-- 
-- While this kind of deeply nested menu is no longer considered good UI
-- practice, it serves as a good example of the concepts in @GMenuModel@.
-- There are 8 ‘menus’ visible in the screenshot: one menubar, two
-- submenus and 5 sections:
-- 
-- * the toplevel menubar (containing 4 items)
-- * the View submenu (containing 3 sections)
-- * the first section of the View submenu (containing 2 items)
-- * the second section of the View submenu (containing 1 item)
-- * the final section of the View submenu (containing 1 item)
-- * the Highlight Mode submenu (containing 2 sections)
-- * the Sources section (containing 2 items)
-- * the Markup section (containing 2 items)
-- 
-- 
-- The <http://developer.gnome.org/gio/stable/#a-menu-example example> illustrates the conceptual connection between
-- these 8 menus. Each large block in the figure represents a menu and the
-- smaller blocks within the large block represent items in that menu. Some
-- items contain references to other menus.
-- 
-- == A menu example
-- 
-- \<picture>
--   \<source srcset=\"menu-model-dark.svg\" media=\"(prefers-color-scheme: dark)\">
--   \<img src=\"menu-model-light.svg\" alt=\"menu model\">
-- \<\/picture>
-- 
-- Notice that the separators visible in the <http://developer.gnome.org/gio/stable/#an-example-menu example>
-- appear nowhere in the <http://developer.gnome.org/gio/stable/#a-menu-example menu model>. This is because
-- separators are not explicitly represented in the menu model. Instead,
-- a separator is inserted between any two non-empty sections of a menu.
-- Section items can have labels just like any other item. In that case,
-- a display system may show a section header instead of a separator.
-- 
-- The motivation for this abstract model of application controls is
-- that modern user interfaces tend to make these controls available
-- outside the application. Examples include global menus, jumplists,
-- dash boards, etc. To support such uses, it is necessary to ‘export’
-- information about actions and their representation in menus, which
-- is exactly what the action group exporter and the menu model exporter do for
-- t'GI.Gio.Interfaces.ActionGroup.ActionGroup' and t'GI.Gio.Objects.MenuModel.MenuModel'. The client-side
-- counterparts to make use of the exported information are
-- t'GI.Gio.Objects.DBusActionGroup.DBusActionGroup' and t'GI.Gio.Objects.DBusMenuModel.DBusMenuModel'.
-- 
-- The API of @GMenuModel@ is very generic, with iterators for the
-- attributes and links of an item, see
-- 'GI.Gio.Objects.MenuModel.menuModelIterateItemAttributes' and
-- 'GI.Gio.Objects.MenuModel.menuModelIterateItemLinks'. The ‘standard’ attributes and
-- link types have predefined names: @G_MENU_ATTRIBUTE_LABEL@,
-- @G_MENU_ATTRIBUTE_ACTION@, @G_MENU_ATTRIBUTE_TARGET@, @G_MENU_LINK_SECTION@
-- and @G_MENU_LINK_SUBMENU@.
-- 
-- Items in a @GMenuModel@ represent active controls if they refer to
-- an action that can get activated when the user interacts with the
-- menu item. The reference to the action is encoded by the string ID
-- in the @G_MENU_ATTRIBUTE_ACTION@ attribute. An action ID uniquely
-- identifies an action in an action group. Which action group(s) provide
-- actions depends on the context in which the menu model is used.
-- E.g. when the model is exported as the application menu of a
-- <https://docs.gtk.org/gtk4/class.Application.html `GtkApplication`>,
-- actions can be application-wide or window-specific (and thus come from
-- two different action groups). By convention, the application-wide actions
-- have names that start with @app.@, while the names of window-specific
-- actions start with @win.@.
-- 
-- While a wide variety of stateful actions is possible, the following
-- is the minimum that is expected to be supported by all users of exported
-- menu information:
-- * an action with no parameter type and no state
-- * an action with no parameter type and boolean state
-- * an action with string parameter type and string state
-- 
-- 
-- == Stateless
-- 
-- A stateless action typically corresponds to an ordinary menu item.
-- 
-- Selecting such a menu item will activate the action (with no parameter).
-- 
-- == Boolean State
-- 
-- An action with a boolean state will most typically be used with a ‘toggle’
-- or ‘switch’ menu item. The state can be set directly, but activating the
-- action (with no parameter) results in the state being toggled.
-- 
-- Selecting a toggle menu item will activate the action. The menu item should
-- be rendered as ‘checked’ when the state is true.
-- 
-- == String Parameter and State
-- 
-- Actions with string parameters and state will most typically be used to
-- represent an enumerated choice over the items available for a group of
-- radio menu items. Activating the action with a string parameter is
-- equivalent to setting that parameter as the state.
-- 
-- Radio menu items, in addition to being associated with the action, will
-- have a target value. Selecting that menu item will result in activation
-- of the action with the target value as the parameter. The menu item should
-- be rendered as ‘selected’ when the state of the action is equal to the
-- target value of the menu item.
