XkbAddGeomColor(3)


NAME

   XkbAddGeomColor  -  Add one color name to an existing keyboard geometry
   description

SYNOPSIS

   XkbColorPtr XkbAddGeomColor (XkbGeometryPtr geom, char *spec,  unsigned
          int pixel);

ARGUMENTS

   - geom geometry to be updated

   - spec color to be added

   - pixel
          color to be added

DESCRIPTION

   Xkb  provides  functions  to  add a single new element to the top-level
   keyboard geometry. In each case the num_ * fields of the  corresponding
   structure  is  incremented  by  1.  These  functions do not change sz_*
   unless there is no more room in the array. Some of these functions fill
   in  the values of the element's structure from the arguments. For other
   functions, you must explicitly  write  code  to  fill  the  structure's
   elements.

   The   top-level  geometry  description  includes  a  list  of  geometry
   properties.  A geometry property associates an arbitrary string with an
   equally  arbitrary  name. Programs that display images of keyboards can
   use geometry properties as hints, but they are not interpreted by  Xkb.
   No other geometry structures refer to geometry properties.

   XkbAddGeomColor  adds  the  specified  color  name  and  pixel  to  the
   specified geometry geom.  The top-level geometry description includes a
   list  of  up  to  MaxColors (32) color names.  A color name is a string
   whose interpretation is not specified by Xkb and neither is  the  pixel
   value's  interpretation.  All  other  geometry data structures refer to
   colors using their indices in this global list or pointers to colors in
   this  list.   XkbAddGeomColor  returns NULL if any of the parameters is
   empty or if it was not  able  to  allocate  space  for  the  color.  To
   allocate space for an arbitrary number of colors to a geometry, use the
   XkbAllocGeomColors function.

STRUCTURES

       typedef struct _XkbColor {
           unsigned int    pixel;      / color */
           char *          spec;       / color name */
       } XkbColorRec,*XkbColorPtr;
