NAME
XkbAddGeomOverlayKey - Add a key to an existing overlay row
SYNOPSIS
XkbOverlayKeyPtr XkbAddGeomOverlayKey (XkbOverlayPtr overlay, XkbRowPtr
row, char *under);
ARGUMENTS
- overlay
overlay to be updated
- row row in overlay to be updated
- under
primary name of the key to be considered
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.
XkbAddGeomOverlayKey adds one key to the row in the overlay. If there
is no key named under in the row of the underlying section,
XkbAddGeomOverlayKey returns NULL.
