    -- Handles the preferred size and allocation for children of a widget.
    --
    -- You typically subclass @GtkLayoutManager@ if you want to implement a
    -- layout policy for the children of a widget, or if you want to determine
    -- the size of a widget depending on its contents.
    --
    -- Each @GtkWidget@ can only have a @GtkLayoutManager@ instance associated
    -- to it at any given time; it is possible, though, to replace the layout
    -- manager instance using 'GI.Gtk.Objects.Widget.widgetSetLayoutManager'.
    --
    -- == Layout properties
    --
    -- A layout manager can expose properties for controlling the layout of
    -- each child, by creating an object type derived from t'GI.Gtk.Objects.LayoutChild.LayoutChild'
    -- and installing the properties on it as normal @GObject@ properties.
    --
    -- Each @GtkLayoutChild@ instance storing the layout properties for a
    -- specific child is created through the 'GI.Gtk.Objects.LayoutManager.layoutManagerGetLayoutChild'
    -- method; a @GtkLayoutManager@ controls the creation of its @GtkLayoutChild@
    -- instances by overriding the GtkLayoutManagerClass.@/create_layout_child()/@
    -- virtual function. The typical implementation should look like:
    --
    --
    -- === /c code/
    -- >static GtkLayoutChild *
    -- >create_layout_child (GtkLayoutManager *manager,
    -- >                     GtkWidget        *container,
    -- >                     GtkWidget        *child)
    -- >{
    -- >  return g_object_new (your_layout_child_get_type (),
    -- >                       "layout-manager", manager,
    -- >                       "child-widget", child,
    -- >                       NULL);
    -- >}
    --
    --
    -- The [LayoutChild:layoutManager]("GI.Gtk.Objects.LayoutChild#g:attr:layoutManager") and
    -- [LayoutChild:childWidget]("GI.Gtk.Objects.LayoutChild#g:attr:childWidget") properties
    -- on the newly created @GtkLayoutChild@ instance are mandatory. The
    -- @GtkLayoutManager@ will cache the newly created @GtkLayoutChild@ instance
    -- until the widget is removed from its parent, or the parent removes the
    -- layout manager.
    --
    -- Each @GtkLayoutManager@ instance creating a @GtkLayoutChild@ should use
    -- 'GI.Gtk.Objects.LayoutManager.layoutManagerGetLayoutChild' every time it needs to query
    -- the layout properties; each @GtkLayoutChild@ instance should call
    -- 'GI.Gtk.Objects.LayoutManager.layoutManagerLayoutChanged' every time a property is
    -- updated, in order to queue a new size measuring and allocation.
