.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.
|
|
|
|
|
|
|
|
|
|
Keys are grouped into rows.
|
|
|
|
|
.I XkbAddGeomKey
|
|
|
|
|
adds one key to the end of the specified
|
|
|
|
|
.I row.
|
|
|
|
|
The key is allocated and zeroed.
|
|
|
|
|
.I XkbAddGeomKey
|
|
|
|
|
returns NULL if
|
|
|
|
|
.I row
|
|
|
|
|
is empty or if it was not able to allocate space for the key. To allocate space for an arbitrary
|
|
|
|
|
number of keys to a row, use
|
|
|
|
|
.I XkbAllocGeomKeys.
