NAME
XkbAddGeomDoodad - Add one doodad to a section of a keyboard geometry
or to the top-level geometry
SYNOPSIS
XkbDoodadPtr XkbAddGeomDoodad (XkbGeometryPtr geom, XkbSectionPtr
section, Atom name);
ARGUMENTS
- geom geometry to which the doodad is added
- section
section, if any, to which the doodad is added
- name name of the new doodad
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.
A doodad describes some visible aspect of the keyboard that is not a
key and is not a section. XkbAddGeomDoodad adds a doodad with name
specified by name to the geometry geom if section is NULL or to the
section of the geometry specified by section if section is not NULL.
XkbAddGeomDoodad returns NULL if any of the parameters is empty or if
it was not able to allocate space for the doodad. If there is already a
doodad with the name name in the doodad array for the geometry (if
section is NULL) or the section (if section is non-NULL), a pointer to
that doodad is returned. To allocate space for an arbitrary number of
doodads to a section, use the XkbAllocGeomSectionDoodads function. To
allocate space for an arbitrary number of doodads to a keyboard
geometry, use the XkbAllocGeomDoodads function.
