XkbUpdateMapFromCore(3) XKB FUNCTIONS XkbUpdateMapFromCore(3)
NAME
XkbUpdateMapFromCore - Update a local Xkb keyboard map to reflect the mapping expressed
by a core format mapping
SYNOPSIS
Bool XkbUpdateMapFromCore (XkbDescPtr xkb, KeyCode first_key, int num_keys, int map_width,
KeySym *core_keysyms, XkbChangesPtr changes);
ARGUMENTS
- xkb keyboard description to update
- first_key
keycode of first key description to update
- num_keys
number of key descriptions to update
- map_width
width of core protocol keymap
- core_keysyms
symbols in core protocol keymap
- changes
backfilled with changes made to Xkb
DESCRIPTION
Xkb provides several functions that make it easier to apply the compatibility map to con-
figure a client-side Xkb keyboard mapping, given a core protocol representation of part or
all of a keyboard mapping. Obtain a core protocol representation of a keyboard mapping
from an actual server (by using XGetKeyboardMapping, for example), a data file, or some
other source.
XkbUpdateMapFromCore interprets input argument information representing a keyboard map in
core format to update the Xkb keyboard description passed in xkb. Only a portion of the
Xkb map is updated - the portion corresponding to keys with keycodes in the range
first_key through first_key + num_keys - 1. If XkbUpdateMapFromCore is being called in
response to a MappingNotify event, first_key and num_keys are reported in the MappingNo-
tify event. core_keysyms contains the keysyms corresponding to the keycode range being
updated, in core keyboard description order. map_width is the number of keysyms per key
in core_keysyms. Thus, the first map_width entries in core_keysyms are for the key with
keycode first_key, the next map_width entries are for key first_key + 1, and so on.
In addition to modifying the Xkb keyboard mapping in xkb, XkbUpdateMapFromCore backfills
the changes structure whose address is passed in changes to indicate the modifications
that were made. You may then use changes in subsequent calls such as XkbSetMap, to propa-
gate the local modifications to a server.
