DEFINITION MODULE FOR "C" GtkBox ;

(*
   m2-GTK4 - GtkBox: a simple one-dimensional container.  Mapped onto
   <gtk/gtkbox.h>.

   GTK4 boxes take no "homogeneous"/"expand" child arguments: append
   or prepend children, then use the per-widget GtkWidget layout
   helpers (hexpand, halign, margins) to control their allocation.
