.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 XkbAddGeomOverlayRow
|
||
|
adds one row to the
|
||
|
.I overlay.
|
||
|
The new row contains space for
|
||
|
.I sz_keys
|
||
|
keys. If
|
||
|
. I row_under
|
||
|
specifies a row that doesn't exist on the underlying section,
|
||
|
.I XkbAddGeomOverlayRow
|
||
|
returns NULL and doesn't change the overlay.
|
||
|
.I XkbAddGeomOverlayRow
|
||
|
returns NULL if any of the parameters is empty or if it was not able to allocate
|
||
|
space for the overlay.
