XkbAddGeomOverlayKey(3) XKB FUNCTIONS XkbAddGeomOverlayKey(3)
NAME
XkbAddGeomOverlayKey - Add a key to an existing overlay row
SYNOPSIS
XkbOverlayKeyPtr XkbAddGeomOverlayKey (XkbOverlayPtr overlay, XkbRowPtr
row, _Xconst char *over, _Xconst 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.
