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.
