color to be added
.SH DESCRIPTION
.LP
Xkb provides functions to add a single new element to the top-level keyboard
geometry. In each case the
.I num_ *
fields of the corresponding structure is incremented by 1. These functions do
not change
.I 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
.I 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.
.I XkbAddGeomColor
adds the specified color
.I name
and
.I pixel
to the specified geometry
.I geom.
The top-level geometry description includes a list of up to MaxColors (32)
.I color names.
A color
.I name
is a string whose interpretation is not specified by Xkb and neither is the
.I 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.
.I 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
.I XkbAllocGeomColors
function.
