Glue, HGlue, VGlue - open space between interactors

SYNOPSIS

       #include <InterViews/glue.h>

DESCRIPTION

       A  glue  object  is  an  interactor that is used to define
       variable-size space between  interactors  in  boxes.   The
       HGlue subclass is for space in a horizontal box; VGlue for
       space in a vertical box.  Along its minor  axis  (vertical
       for  HGlue, horizontal for VGlue), glue has a natural size
       of zero and infinite stretchability.

PUBLIC OPERATIONS

       HGlue(int natural = 0, int stretch = hfil)
       VGlue(int natural = 0, int stretch = vfil)
              Construct  glue  with  a  given  natural  size  and
              stretchability.    The   glue's   shrinkability  is
              defined to be the same as the natural size, meaning
              it can shrink to zero.

       HGlue(int natural, int shrink, int stretch)
       VGlue(int natural, int shrink, int stretch)
              Construct  glue with a given natural size, shrinka-
              bility, and stretchability.  If  shrink  is  larger
              than  natural the glue potentially can have ``nega-
              tive size'', meaning interactors will overlap in  a
              box.
