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.
