.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.
