XkbAddGeomColor(3)               XKB FUNCTIONS              XkbAddGeomColor(3)


NAME

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


SYNOPSIS

       XkbColorPtr XkbAddGeomColor (XkbGeometryPtr geom, _Xconst 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;
