    /// [`PopoverMenu`][crate::PopoverMenu] is a subclass of [`Popover`][crate::Popover] that implements menu
    /// behavior.
    ///
    /// ![An example GtkPopoverMenu](menu.png)
    ///
    /// [`PopoverMenu`][crate::PopoverMenu] treats its children like menus and allows switching
    /// between them. It can open submenus as traditional, nested submenus,
    /// or in a more touch-friendly sliding fashion.
    ///
    /// [`PopoverMenu`][crate::PopoverMenu] is meant to be used primarily with menu models,
    /// using [``from_model()``][`Self::from_model()`]. If you need to put
    /// other widgets such as a [`SpinButton`][crate::SpinButton] or a [`Switch`][crate::Switch] into a popover,
    /// you can use [``add_child()``][`Self::add_child()`].
    ///
    /// For more dialog-like behavior, use a plain [`Popover`][crate::Popover].
    ///
    /// ## Menu models
    ///
    /// The XML format understood by [`Builder`][crate::Builder] for `GMenuModel` consists
    /// of a toplevel ``<menu>`` element, which contains one or more ``<item>``
    /// elements. Each ``<item>`` element contains ``<attribute>`` and ``<link>``
    /// elements with a mandatory name attribute. ``<link>`` elements have the
    /// same content model as ``<menu>``. Instead of `<link name="submenu">`
    /// or `<link name="section">`, you can use ``<submenu>`` or ``<section>``
    /// elements.
    ///
    /// ```xml
    /// <menu id='app-menu'>
    ///   <section>
    ///     <item>
    ///       <attribute name='label' translatable='yes'>_New Window</attribute>
    ///       <attribute name='action'>app.new</attribute>
    ///     </item>
    ///     <item>
    ///       <attribute name='label' translatable='yes'>_About Sunny</attribute>
    ///       <attribute name='action'>app.about</attribute>
    ///     </item>
    ///     <item>
    ///       <attribute name='label' translatable='yes'>_Quit</attribute>
    ///       <attribute name='action'>app.quit</attribute>
    ///     </item>
    ///   </section>
    /// </menu>
    /// ```
    ///
    /// Attribute values can be translated using gettext, like other [`Builder`][crate::Builder]
    /// content. ``<attribute>`` elements can be marked for translation with a
    /// `translatable="yes"` attribute. It is also possible to specify message
    /// context and translator comments, using the context and comments attributes.
    /// To make use of this, the [`Builder`][crate::Builder] must have been given the gettext
    /// domain to use.
    ///
    /// The following attributes are used when constructing menu items:
    ///
    /// - "label": a user-visible string to display
    /// - "action": the prefixed name of the action to trigger
    /// - "target": the parameter to use when activating the action
    /// - "icon" and "verb-icon": names of icons that may be displayed
    /// - "submenu-action": name of an action that may be used to track
    ///  whether a submenu is open
    /// - "hidden-when": a string used to determine when the item will be hidden.
    ///  Possible values include "action-disabled", "action-missing", "macos-menubar".
    ///  This is mainly useful for exported menus, see [``GtkApplicationExt::set_menubar()``][crate::prelude::`GtkApplicationExt::set_menubar()`].
    /// - "custom": a string used to match against the ID of a custom child added with
    ///  [``add_child()``][`Self::add_child()`], [``PopoverMenuBar::add_child()``][crate::`PopoverMenuBar::add_child()`],
    ///  or in the ui file with `<child type="ID">`.
    ///
    /// The following attributes are used when constructing sections:
    ///
    /// - "label": a user-visible string to use as section heading
    /// - "display-hint": a string used to determine special formatting for the section.
    ///  Possible values include "horizontal-buttons", "circular-buttons" and
    ///  "inline-buttons". They all indicate that section should be
    ///  displayed as a horizontal row of buttons.
    /// - "text-direction": a string used to determine the [`TextDirection`][crate::TextDirection] to use
    ///  when "display-hint" is set to "horizontal-buttons". Possible values
    ///  include "rtl", "ltr", and "none".
    ///
    /// The following attributes are used when constructing submenus:
    ///
    /// - "label": a user-visible string to display
    /// - "icon": icon name to display
    ///
    /// Menu items will also show accelerators, which are usually associated
    /// with actions via [``GtkApplicationExt::set_accels_for_action()``][crate::prelude::`GtkApplicationExt::set_accels_for_action()`],
    /// [`WidgetClass::add_binding_action`][crate::WidgetClass::add_binding_action] or
