.TH XkbAddGeomKey __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAddGeomKey \- Add one key at the end of an existing row of keys
.SH SYNOPSIS
.HP
.B XkbKeyPtr XkbAddGeomKey
.BI "(\^XkbRowPtr " "row" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- row
row to be updated
.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.
Keys are grouped into rows.
.I XkbAddGeomKey
adds one key to the end of the specified
.I row.
The key is allocated and zeroed.
.I XkbAddGeomKey
returns NULL if
.I row
is empty or if it was not able to allocate space for the key. To allocate space for an arbitrary
number of keys to a row, use
.I XkbAllocGeomKeys.
