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.

STRUCTURES

typedef struct _XkbOverlayKey {
XkbKeyNameRec over; /* name of this overlay key */
XkbKeyNameRec under; /* name of the key under this overlay key */
} XkbOverlayKeyRec,*XkbOverlayKeyPtr;
