    /// [`ViewStack`][crate::ViewStack] is a container which only shows one page at a time.
    /// It is typically used to hold an application's main views.
    ///
    /// It doesn't provide a way to transition between pages.
    /// Instead, a separate widget such as [`ViewSwitcher`][crate::ViewSwitcher],
    /// [`InlineViewSwitcher`][crate::InlineViewSwitcher] or [`ViewSwitcherSidebar`][crate::ViewSwitcherSidebar] can be used with
    /// [`ViewStack`][crate::ViewStack] to provide this functionality.
    ///
    /// [`ViewStack`][crate::ViewStack] pages can have a title, an icon, an attention request, and a
    /// numbered badge that [`ViewSwitcher`][crate::ViewSwitcher] will use to let users identify which
    /// page is which. Set them using the [`title`][struct@crate::ViewStackPage#title],
    /// [`icon-name`][struct@crate::ViewStackPage#icon-name],
    /// [`needs-attention`][struct@crate::ViewStackPage#needs-attention], and
    /// [`badge-number`][struct@crate::ViewStackPage#badge-number] properties.
    ///
    /// [`ViewStack`][crate::ViewStack] pages can also be grouped into sections, using the
    /// [`starts-section`][struct@crate::ViewStackPage#starts-section] and
    /// [`section-title`][struct@crate::ViewStackPage#section-title] properties. Currently, only
    /// [`ViewSwitcherSidebar`][crate::ViewSwitcherSidebar] displays groups.
    ///
    /// Unlike [`gtk::Stack`][crate::gtk::Stack], transitions between views can only be animated via
    /// a crossfade and size changes are always interpolated. Animations are disabled
    /// by default. Use [`enable-transitions`][struct@crate::ViewStack#enable-transitions] to enable them.
    ///
    /// [`ViewStack`][crate::ViewStack] maintains a [`ViewStackPage`][crate::ViewStackPage] object for each added child,

    /// ## Properties
    ///
    ///
    /// #### `enable-transitions`
    ///  Whether the stack uses a crossfade transition between pages.

    ///  A selection model with the stack's pages.

    ///  Whether a transition is currently running.
    ///
    /// If a transition is impossible, the property value will be set to `TRUE` and
    /// then immediately to `FALSE`, so it's possible to rely on its notifications
