XkbSetIndicatorMap(3) XKB FUNCTIONS XkbSetIndicatorMap(3)
NAME
XkbSetIndicatorMap - Downloads the changes to the server based on modi-
fications to a local copy of the keyboard description which will update
the maps for one or more indicators
SYNOPSIS
Bool XkbSetIndicatorMap (Display *dpy, unsigned int which, XkbDescPtr
desc);
ARGUMENTS
dpy connection to the X server
which mask of indicators to change
desc keyboard description from which the maps are taken
DESCRIPTION
This section discusses the effects of explicitly changing indicators de-
pending upon different settings in the indicator map. See Tables 1 and
Table 2 for information on the effects of the indicator map fields when
explicit changes are made.

Indicator Drives Keyboard
────────────────────────────────────────────────────────────────
which_groups New State Effect on Keyboard Group State
────────────────────────────────────────────────────────────────
XkbIM_UseNone On or Off No effect
XkbIM_UseBase On or Off No effect
XkbIM_UseLatched On The groups field is treated as
a group mask. The keyboard
group latch is changed to the
lowest numbered group speci-
fied in groups; if groups is
empty, the keyboard group
latch is changed to zero.
XkbIM_UseLatched Off The groups field is treated as
a group mask. If the indicator
is explicitly extinguished,
keyboard group latch is
changed to the lowest numbered
group not specified in groups;
if groups is zero, the key-
board group latch is set to
the index of the highest legal
keyboard group.
XkbIM_UseLocked or
XkbIM_UseEffective On If the groups mask is empty,
group is not changed; other-
wise, the locked keyboard
group is changed to the lowest
numbered group specified in
groups.
XkbIM_UseLocked or
XkbIM_UseEffective Off Locked keyboard group is
changed to the lowest numbered
group that is not specified in
the groups mask, or to Group1
if the groups mask contains
all keyboard groups.

─────────────────────────────────────────────────────────────────
XkbIM_UseNone or
XkbIM_UseBase On or Off No Effect
XkbIM_UseLatched On Any modifiers specified in the
mask field of mods are added
to the latched modifiers.
XkbIM_UseLatched Off Any modifiers specified in the
mask field of mods are removed
from the latched modifiers.
XkbIM_UseLocked,
XkbIM_UseCompat, or
XkbIM_UseEffective On Any modifiers specified in the
mask field of mods are added
to the locked modifiers.
XkbIM_UseLocked Off Any modifiers specified in the
mask field of mods are removed
from the locked modifiers.
XkbIM_UseCompat or
XkbIM_UseEffective Off Any modifiers specified in the
mask field of mods are removed
from both the locked and
latched modifiers.
If XkbIM_LEDDrivesKB is set and XkbIM_NoExplicit is not, and if you call
a function that updates the server's image of the indicator map (such as
XkbSetIndicatorMap or XkbSetNamedIndicator), Xkb changes the keyboard
state and controls to reflect the other fields of the indicator map. If
you attempt to explicitly change the value of an indicator for which Xk-
bIM_LEDDrivesKB is absent or for which XkbIM_NoExplicit is present, key-
board state or controls are unaffected.
If neither XkbIM_NoAutomatic nor XkbIM_NoExplicit is set in an indicator
map, Xkb honors any request to change the state of the indicator, but
the new state might be immediately superseded by automatic changes to
the indicator state if the keyboard state or controls change.
The effects of changing an indicator that drives the keyboard are cumu-
lative; it is possible for a single change to affect keyboard group,
modifiers, and controls simultaneously.
If you change an indicator for which both the XkbIM_LEDDrivesKB and Xk-
bIM_NoAutomatic flags are specified, Xkb applies the keyboard changes
specified in the other indicator map fields and changes the indicator to
reflect the state that was explicitly requested. The indicator remains
in the new state until it is explicitly changed again.
If the XkbIM_NoAutomatic flag is not set and XkbIM_LEDDrivesKB is set,
Xkb applies the changes specified in the other indicator map fields and
sets the state of the indicator to the values specified by the indicator
map. Note that it is possible in this case for the indicator to end up
in a different state than the one that was explicitly requested. For ex-
ample, Xkb does not extinguish an indicator with which_mods of Xk-
bIM_UseBase and mods of Shift if, at the time Xkb processes the request
to extinguish the indicator, one of the Shift keys is physically de-
pressed.
If you explicitly light an indicator for which XkbIM_LEDDrivesKB is set,
Xkb enables all of the boolean controls specified in the ctrls field of
its indicator map. Explicitly extinguishing such an indicator causes Xkb
to disable all of the boolean controls specified in ctrls.
For each bit set in the which parameter, XkbSetIndicatorMap sends the
corresponding indicator map from the desc parameter to the server.
