NAME
XkbSetIndicatorMap - Downloads the changes to the server based on modifications 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 depending 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.
Table 1 XkbIndicatorMapRec which_groups and groups,
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
specified 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
keyboard 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;
otherwise, 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.
Table 2 XkbIndicatorMapRec which_mods and mods,

─────────────────────────────────────────────────────────────────
which_mods New State Effect on Keyboard Modifiers
─────────────────────────────────────────────────────────────────
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 XkbIM_LEDDrivesKB is absent or for which
XkbIM_NoExplicit is present, keyboard 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 cumulative; 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 XkbIM_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 example, Xkb does not extinguish an indicator with
which_mods of XkbIM_UseBase and mods of Shift if, at the time Xkb processes the request to extinguish the
indicator, one of the Shift keys is physically depressed.
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.
