-- Layout managers are delegate classes that handle the preferred size
-- and the allocation of a container widget.
-- 
-- You typically subclass t'GI.Gtk.Objects.LayoutManager.LayoutManager' 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 t'GI.Gtk.Objects.Widget.Widget' can only have a t'GI.Gtk.Objects.LayoutManager.LayoutManager' 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 t'GI.Gtk.Objects.LayoutChild.LayoutChild' instance storing the layout properties for a
-- specific child is created through the 'GI.Gtk.Objects.LayoutManager.layoutManagerGetLayoutChild'
-- method; a t'GI.Gtk.Objects.LayoutManager.LayoutManager' controls the creation of its t'GI.Gtk.Objects.LayoutChild.LayoutChild'
-- 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 t'GI.Gtk.Objects.LayoutChild.LayoutChild':@/layout-manager/@ and t'GI.Gtk.Objects.LayoutChild.LayoutChild':@/child-widget/@ properties
-- on the newly created t'GI.Gtk.Objects.LayoutChild.LayoutChild' instance are mandatory. The
-- t'GI.Gtk.Objects.LayoutManager.LayoutManager' will cache the newly created t'GI.Gtk.Objects.LayoutChild.LayoutChild' instance until
-- the widget is removed from its parent, or the parent removes the layout
-- manager.
-- 
-- Each t'GI.Gtk.Objects.LayoutManager.LayoutManager' instance creating a t'GI.Gtk.Objects.LayoutChild.LayoutChild' should use
-- 'GI.Gtk.Objects.LayoutManager.layoutManagerGetLayoutChild' every time it needs to query the
-- layout properties; each t'GI.Gtk.Objects.LayoutChild.LayoutChild' instance should call
-- 'GI.Gtk.Objects.LayoutManager.layoutManagerLayoutChanged' every time a property is updated, in
-- order to queue a new size measuring and allocation.
