    /// GtkPopoverMenu is a subclass of [`Popover`][crate::Popover] that treats its
    /// children like menus and allows switching between them. It is
    /// meant to be used primarily together with [`ModelButton`][crate::ModelButton], but
    /// any widget can be used, such as [`SpinButton`][crate::SpinButton] or [`Scale`][crate::Scale].
    /// In this respect, GtkPopoverMenu is more flexible than popovers
    /// that are created from a [`gio::MenuModel`][crate::gio::MenuModel] with [`Popover::from_model()`][crate::Popover::from_model()].
    ///
    /// To add a child as a submenu, set the `property::PopoverMenu::submenu`
    /// child property to the name of the submenu. To let the user open
    /// this submenu, add a [`ModelButton`][crate::ModelButton] whose `property::ModelButton::menu-name`
    /// property is set to the name you've given to the submenu.
    ///
    /// By convention, the first child of a submenu should be a [`ModelButton`][crate::ModelButton]
    /// to switch back to the parent menu. Such a button should use the
    /// `property::ModelButton::inverted` and `property::ModelButton::centered` properties
    /// to achieve a title-like appearance and place the submenu indicator
    /// at the opposite side. To switch back to the main menu, use "main"
    /// as the menu name.
    ///
