XkbAddGeomOutline(3) XKB FUNCTIONS XkbAddGeomOutline(3)

NAME

XkbAddGeomOutline - Add one outline to an existing shape

SYNOPSIS

XkbOutlinePtr XkbAddGeomOutline (XkbShapePtr shape, int sz_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.

STRUCTURES

typedef struct _XkbOutline {
unsigned short num_points; /* number of points in the outline */
unsigned short sz_points; /* size of the points array */
unsigned short corner_radius; /* draw corners as circles with this radius */
XkbPointPtr points; /* array of points defining the outline */
} XkbOutlineRec, *XkbOutlinePtr;
