.TH XkbAddGeomOverlayKey __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAddGeomOverlayKey \- Add a key to an existing overlay row
.SH SYNOPSIS
.HP

.BI "XkbRowPtr " "row" "\^,"
.BI "char *" "under" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- overlay
overlay to be updated
.TP
.I \- row
row in overlay to be updated
.TP
.I \- under
primary name of the key to be considered
.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.
.I XkbAddGeomOverlayKey
adds one key to the
.I row
in the
.I overlay.
If there is no key named
.I under
in the row of the underlying section,
.I XkbAddGeomOverlayKey
returns NULL.
