.TH XkbAddGeomOverlay __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAddGeomOverlay \- Add one overlay to a section
.SH SYNOPSIS
.HP
.B XkbOverlayPtr XkbAddGeomOverlay
.BI "(\^XkbSectionPtr " "section" "\^,"
.BI "Atom " "name" "\^,"
.BI "int " "sz_rows" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- section
section to which an overlay will be added
.TP
.I \- name
name of the overlay
.TP
.I \- sz_rows
number of rows to reserve in the overlay
.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 XkbAddGeomOverlay
adds an overlay with the specified name to the specified
.I section.
The new overlay is created with space allocated for
.I sz_rows
rows. If an overlay with name
.I name
already exists in the section, a pointer to the existing overlay is returned.
.I XkbAddGeomOverlay
returns NULL if any of the parameters is empty or if it was not able to allocate
space for the overlay. To allocate space for an arbitrary number of overlays to
a section, use the
.I XkbAllocGeomOverlay
function.
