XkbAddGeomKey(3) XKB FUNCTIONS XkbAddGeomKey(3)
NAME
XkbAddGeomKey - Add one key at the end of an existing row of keys
SYNOPSIS
XkbKeyPtr XkbAddGeomKey (XkbRowPtr row);
ARGUMENTS
row row to be updated
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.
Keys are grouped into rows. XkbAddGeomKey adds one key to the end of the
specified row. The key is allocated and zeroed. XkbAddGeomKey returns
NULL if 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
XkbAllocGeomKeys.
