    /// The `BisLapel` widget can display its children like a `Gtk::Box` does or
    /// like a `Gtk::Overlay` does, according to the
    /// [`fold-policy`][struct@crate::Lapel#fold-policy] value.
    ///
    /// `BisLapel` has at most three children: [`content`][struct@crate::Lapel#content],
    /// [`lapel`][struct@crate::Lapel#lapel] and [`separator`][struct@crate::Lapel#separator]. Content is the primary
    /// child, lapel is displayed next to it when unfolded, or overlays it when
    /// folded. Lapel can be shown or hidden by changing the
    /// [`reveal-lapel`][struct@crate::Lapel#reveal-lapel] value, as well as via swipe gestures if
    /// [`swipe-to-open`][struct@crate::Lapel#swipe-to-open] and/or [`swipe-to-close`][struct@crate::Lapel#swipe-to-close] are set

    ///
    /// Optionally, a separator can be provided, which would be displayed between
    /// the content and the lapel when there's no shadow to separate them, depending
    /// on the transition type.
    ///
    /// [`lapel`][struct@crate::Lapel#lapel] is transparent by default; add the
    /// [`.background`](style-classes.html#background) style class to it if this is

    ///
    /// Folding the lapel will automatically hide the lapel widget, and unfolding it
    /// will automatically reveal it. If this behavior is not desired, the

    /// Common use cases include sidebars, header bars that need to be able to

    /// ## BisLapel as GtkBuildable
    ///
    /// The `BisLapel` implementation of the [`gtk::Buildable`][crate::gtk::Buildable] interface supports

    /// ## CSS nodes
    ///
    /// `BisLapel` has a single CSS node with name `lapel`. The node will get the style
    /// classes `.folded` when it is folded, and `.unfolded` when it's not.
    ///
    /// ## Properties
    ///
    ///
    /// #### `content`
    ///  The content widget.
    ///
    /// It's always displayed when unfolded, and partially visible when folded.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `fold-duration`
    ///  The fold transition animation duration, in milliseconds.

    ///
    /// #### `fold-threshold-policy`
    ///  Determines when the lapel will fold.
    ///
    /// If set to `BIS_FOLD_THRESHOLD_POLICY_MINIMUM`, lapel will only fold when
    /// the children cannot fit anymore. With `BIS_FOLD_THRESHOLD_POLICY_NATURAL`,
    /// it will fold as soon as children don't get their natural size.
    ///
    /// This can be useful if you have a long ellipsizing label and want to let it
    /// ellipsize instead of immediately folding.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `folded`

    ///
    /// #### `locked`
    ///  Whether the lapel is locked.
    ///
    /// If `FALSE`, folding when the lapel is revealed automatically closes it, and

    /// Readable | Writeable
    ///
    ///
    /// #### `modal`
    ///  Whether the lapel is modal.
    ///
    /// If `TRUE`, clicking the content widget while lapel is revealed, as well as
