NAME
XkbAddGeomRow - Add a row to a section
SYNOPSIS
XkbRowPtr XkbAddGeomRow (XkbSectionPtr section, int sz_keys);
ARGUMENTS
- section
section to be updated
- sz_keys
number of keys to be reserved
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.
One of the components of a keyboard geometry section is one or more
rows of keys. XkbAddGeomRow adds one row to the specified section.
The newly created row contains space for the number of keys specified
in sz_keys. They are allocated and zeroed, but otherwise
uninitialized. XkbAddGeomRow returns NULL if any of the parameters is
empty or if it was not able to allocate space for the row. To allocate
space for an arbitrary number of rows to a section, use the
XkbAllocGeomRows function.
