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.
