.TH XkbAddGeomOutline __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAddGeomOutline \- Add one outline to an existing shape
.SH SYNOPSIS
.HP
.B XkbOutlinePtr XkbAddGeomOutline
.BI "(\^XkbShapePtr " "shape" "\^,"
.BI "int " "sz_points" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- shape
shape to be updated
.TP
.I \- sz_points
number of points to be reserved
.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.
An outline consists of an arbitrary number of points.
.I XkbAddGeomOutline
adds an outline to the specified
.I shape
by reserving
.I sz_points
points for it. The new outline is allocated and zeroed.
.I XkbAddGeomOutline
returns NULL if any of the parameters is empty or if it was not able to allocate
space. To allocate space for an arbitrary number of outlines to a shape, use
.I XkbAllocGeomOutlines.
