XkbAddGeomOutline
− Add one outline to an existing shape

SYNOPSIS

XkbOutlinePtr
XkbAddGeomOutline

(XkbShapePtrshape, intsz_points);

ARGUMENTS

−
shape

shape to be updated

− sz_points

number of points 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.

An outline
consists of an arbitrary number of points.
XkbAddGeomOutline adds an outline to the specified
shape by reserving sz_points points for it.
The new outline is allocated and zeroed.
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 XkbAllocGeomOutlines.
