XkbSetIndicatorMap(3) XKB FUNCTIONS XkbSetIndicatorMap(3)
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,
Indicator Drives Keyboard
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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.
