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.

STRUCTURES

typedef struct _XkbKey { /* key in a row */
XkbKeyNameRec name; /* key name */
short gap; /* gap in mm/10 from previous key in row */
unsigned char shape_ndx; /* index of shape for key */
unsigned char color_ndx; /* index of color for key body */
} XkbKeyRec, *XkbKeyPtr;
