XKB Protocol Requests
This document uses the syntactic conventions and common types defined by the
specification of the core X protocol with a number of additions, which are
detailed below.
Errors
If a client attempts to use any other XKB request except
XkbUseExtension
before the extension is properly initialized, XKB reports an
Access
error and ignores the request. XKB is properly initialized once
XkbUseExtension
reports that the client has asked for a supported or compatible version of the
extension.
Keyboard Errors
In addition to all of the errors defined by the core protocol, the X Keyboard
Extension defines a single error,
Keyboard
, which indicates that some request specified an illegal device identifier or
an extension device that is not a member of an appropriate. Unless otherwise
noted, any request with an argument of type KB_DEVICESPEC can cause
Keyboard
errors if an illegal or inappropriate device is specified.
When the extension reports a Keyboard error, the most significant byte of the
resource_id
is a further refinement of the error cause, as defined in the table below. The
least significant byte contains the device, class, or feedback id as indicated:
high-order bytevaluemeaninglow-order byteXkbErr_BadDevice0xffdevice not founddevice idXkbErr_BadClass0xfedevice found, but is the wrong classclass idXkbErr_BadId0xfddevice found, class ok, but device does not have a feedback with the
indicated idfeedback idSide-Effects of Errors
With the exception of
Alloc
or
Implementation
errors, which might result in an inconsistent internal state, no XKB request
that reports an error condition has any effect. Unless otherwise stated,
requests which update some aspect of the keyboard description will not apply
only part of a request — if part of a request fails, the whole thing is
ignored.
Common Types
The following types are used in the request and event definitions in subsequent
sections:
NameValueLISTofITEMs The type LISTofITEMs is special. It is similar to the
LISTofVALUE defined by the core protocol, but the elements of a LISTofITEMs are
not necessarily all the same size. The use of a BITMASK to indicate which
members are present is optional for a LISTofITEMs — it is possible for the
set of elements to be derived from one or more fields of the request.KB_DEVICESPEC8 bit unsigned integer,

This section lists all of the requests supported by the X Keyboard Extension,
separated into categories of related requests.
Initializing the X Keyboard ExtensionXkbUseExtensionwantedMajor, wantedMinor: CARD16
supported: BOOL
serverMajor, serverMinor: CARD16
This request enables XKB extension capabilities for the client that issues the
request; the
wantedMajor
and
wantedMinor
fields specify the extension version in use by the requesting client. The
supported
field is
True
if the server supports a compatible version,
False
otherwise. The
serverMajor
and
serverMinor
fields return the actual version supported by the server.
Until a client explicitly and successfully requests the XKB extension, an XKB
capable server reports compatibility state in all core protocol events and
requests. Once a client asks for XKB extension semantics by issuing this
request, the server reports the extended XKB keyboard state in some core
protocol events and requests, as described in the overview section of this
specification.
Clients should issue an
XkbUseExtension
request before using any other extension requests.

Value
This request updates the event masks of the keyboard indicated by
deviceSpec
for this client. If
deviceSpec
specifies an illegal device, a
Keyboard
error results.
The
affectMap
and
map
fields specify changes to the event details mask for the
XkbMapNotify
event. If any map components are set in
map
but not in
affectMap
, a
Match
error results. Otherwise, any map components that are set in
affectMap
are set or cleared in the map notify details mask, depending on the value of
the corresponding field in
map
.
The
affectWhich
,
clear
, and
selectAll
fields specify changes to any other event details masks. If any event types
are set in both
clear
and
selectAll
, a
Match
error results; if any event types are specified in either
clear
or
selectAll
but not in
affectWhich
, a
Match
error results. Otherwise, the detail masks for any event types specified in
the
affectWhich
field of this request are changed as follows:
If the event type is also set in
clear
, the detail mask for the corresponding event is set to
0
or
False
, as appropriate.
If the event type is also set in
selectAll
, the detail mask for the corresponding event is set to include all legal
detail values for that type.
If the event type is not set in either
clear
or
selectAll
, the corresponding element of
details
lists a set of explicit changes to the details mask for the event, as
described below.
Each entry of the
details
list specifies changes to the event details mask for a single type of event,
and consists of an
affects
mask and a
values
mask. All details that are specified in
affects
are set to the corresponding value from
values
; if any details are listed in
values
but not in
affects
, a
Match
error results.
The details list contains entries only for those event types, if any, that are
listed in the
affectWhich
mask and not in either
clear
or
selectAll
. When present, the items of the
details
list appear in the following order:

This request generates audible bells and/or
XkbBellNotify
events for the bell specified by the
bellClass
and
bellID
on the device specified by
deviceSpec
at the specified
pitch
,
duration
and volume (
percent
). If deviceSpec specifies a device that does not have a bell or keyboard
feedback, a
Keyboard
error results.
If both
forceSound
and
eventOnly
are set, this request yields a
Match
error. Otherwise, if
forceSound
is
True
, this request always generates a sound and never generates an event; if
eventOnly
is
True
, it causes an event but no sound. If neither
forceSound
nor
eventOnly
are
True
, this request always generates an event; if the keyboard’s global
AudibleBell
control is enabled, it also generates a sound.
Any bell event generated by this request contains all of the information about
the bell that was requested, including the symbolic name specified by
name
and the event window specified by window. The
name
and
window
are not directly interpreted by XKB, but they must have the value
None
or specify a legal Atom or Window, respectively.
XkbBellNotify
events generated in response to core protocol or X input extension bell
requests always report
None
as their
name
.
The
bellClass
,
bellID
, and
percent
fields are interpreted as for the X input extension
DeviceBell
request. If
pitch
and
duration
are zero, the server uses the corresponding values for that bell from the core
protocol or input extension, otherwise
pitch
and
duration
are interpreted as for the core protocol
ChangeKeyboardControl
request; if they do not include legal values, a
Value
error results. The
window
field must specify a legal Window or have the value
None
, or a
Value
error results. The name field must specify a legal Atom or have the value
None
, or an
Atom
error results. If an error occurs, this request has no other effect (i.e. does
not cause a sound or generate an event).
The
pitch
,
volume
, and
duration
are suggested values for the bell, but XKB does not require the server to
honor them.

This request returns a detailed description of the current state of the
keyboard specified by
deviceSpec
.
The
deviceID
return value contains the input extension identifier for the specified device,
or
0
if the server does not support the input extension.
The
baseMods
return value reports the modifiers that are set because one or more modifier
keys are logically down. The
latchedMods
and
lockedMods
return values report the modifiers that are latched or locked respectively.
The
mods
return value reports the effective modifier mask which results from the
current combination of base, latched and locked modifiers.
The
baseGroup
return value reports the group state selected by group shift keys that are
logically down. The
latchedGroup
and
lockedGroup
return values detail the effects of latching or locking group shift keys and
XkbLatchLockState
requests. The
group
return value reports the effective keyboard group which results from the
current combination of base, latched and locked group values.
The
lookupMods
return value reports the lookup modifiers, which consist of the current
effective modifiers minus any server internal modifiers. The
grabMods
return value reports the grab modifiers, which consist of the lookup modifiers
minus any members of the ignore locks mask that are not either latched or
logically depressed. Keyboard
State describes the lookup modifiers and grab modifiers in more detail.
The
ptrBtnState
return value reports the current logical state of up to five buttons on the
core pointer device.
The
compatState
return value reports the compatibility state that corresponds to the effective
keyboard group and modifier state. The
compatLookupMods
and
compatGrabMods
return values report the core protocol compatibility states that correspond to
the XKB lookup and grab state. All of the compatibility states are computed by
applying the group compatibility mapping to the corresponding XKB modifier and
group states, as described in
Group Compatibility Map.

Value
This request locks or latches keyboard modifiers and group state for the device
specified by
deviceSpec
. If
deviceSpec
specifies an illegal or non-keyboard device, a
Keyboard
error occurs.
The locked state of any modifier specified in the
affectModLocks
mask is set to the corresponding value from
modLocks
. If
lockGroup
is
True
, the locked keyboard group is set to the group specified by
groupLock
. If any modifiers are set in
modLocks
but not
affectModLocks
, a
Match
error occurs.
The latched state of any modifier specified in the
affectModLatches
mask is set to the corresponding value from
modLatches
. If
latchGroup
is
True
, the latched keyboard group is set to the group specified by
groupLatch
. if any modifiers are set in
modLatches
but not in
affectModLatches
, a
Match
error occurs.
If the locked group exceeds the maximum number of groups permitted for the
specified keyboard, it is wrapped or truncated back into range as specified by
the global
GroupsWrap
control. No error results from an out-of-range group specification.
After changing the locked and latched modifiers and groups as specified, the X
server recalculates the effective and compatibility keyboard state and
generates
XkbStateNotify
events as appropriate if any state components have changed. Changing the
keyboard state might also turn indicators on or off which can cause
XkbIndicatorStateNotify
events as well.
If any errors occur, this request has no effect.

This request returns the current values and status of all controls for the
keyboard specified by
deviceSpec
. If
deviceSpec
specifies an illegal device a
Keyboard
error results. On return, the
deviceID
specifies the identifier of the requested device or zero if the server does
not support the input extension.
The
numGroups
return value reports the current number of groups, and
groupsWrap
reports the treatment of out-of-range groups, as described in Key Symbol Map. The
internalMods
and
ignoreLockMods
return values report the current values of the server internal and ignore
locks modifiers as described in

The
mouseKeysDfltBtn
return value reports the current default pointer button for which events are
synthesized by the mouse keys server actions.
The
accessXOptions
return value reports the current settings of the various AccessX options flags
which govern the behavior of the
StickyKeys
control and of AccessX feedback.
The
accessXTimeout
return value reports the length of time, in seconds, that the keyboard must
remain idle before AccessX controls are automatically changed; an
accessXTimeout
of
0
indicates that AccessX controls are not automatically changed. The
accessXTimeoutMask
specifies the boolean controls to be changed if the AccessX timeout expires;
the
accessXTimeoutValues
field specifies new values for all of the controls in the timeout mask. The
accessXTimeoutOptionsMask
field specifies the AccessX options to be changed when the AccessX timeout
expires; the
accessXTimeoutOptionValues
return value reports the values to which they will be set.
The
enabledControls
return value reports the current state of all of the global boolean controls.
The
perKeyRepeat
array consists of one bit per key and reports the current autorepeat behavior
of each keyboard key; if a bit is set in
perKeyRepeat
, the corresponding key repeats if it is held down while global keyboard
autorepeat is enabled. This array parallels the core protocol and input
extension keyboard controls, if the autorepeat behavior of a key is changed via
the core protocol or input extension, those changes are automatically reflected
in the
perKeyRepeat
array.

must be non-zero or a
Value
error results.
If applied, the
mouseKeysDfltBtn
field specifies the core pointer button for which events are generated
whenever a
SA_PtrBtn
or
SA_LockPtrBtn
key action is activated. If present,
mouseKeysDfltBtn
must specify a legal button for the core pointer device, or a
Value
error results. Key
Actions describes the
SA_PtrBtn
and
SA_LockPtrBtn
actions in more detail.
If applied, the
mouseKeysDelay
,
mouseKeysInterval
,
mouseKeysTimeToMax
,
mouseKeysMaxSpeed
and
mouseKeysCurve
fields change the rate at which the pointer moves when a key which generates a
SA_MovePtr
action is held down. The
MouseKeysAccel Control describes these
MouseKeysAccel
parameters in more detail. If defined, the
mouseKeysDelay
,
mouseKeysInterval
,
mouseKeysTimeToMax
and
mouseKeysMaxSpeed
values must all be greater than zero, or a
Value
error results. The
mouseKeysCurve
value must be greater than
-1000
or a
Value
error results.
If applied, the
accessXOptions
field sets the AccessX options, which are described in detail in
The AccessXKeys Control. If
either one of
XkbStickyKeysMask
and
XkbAccessXFeedbackMask
are set in
changeControls
and
XkbAccessXKeysMask
is not, only a subset of the AccessX options are changed, as described in the
table above; if both are set or if the
AccessXKeys
bit is set in
changeControls
, all of the AccessX options are updated. Any bit in
accessXOptions
whose interpretation is undefined must be zero, or a
Value
error results.
If applied, the
accessXTimeout
,
accessXTimeoutMask
,
accessXTimeoutValues
,
accessXTimeoutOptionsMask
and
accessXTimeoutOptionsValues
fields change the behavior of the AccessX Timeout control, as described in
The AccessXTimeout
Control. The
accessXTimeout
must be greater than zero, or a
Value
error results. The
accessXTimeoutMask
or
accessXTimeoutValues
fields must specify only legal boolean controls, or a
Value
error results. The
accessXTimeoutOptionsMask
and
accessXTimeoutOptionsValues
fields must contain only legal AccessX options or a
Value
error results. If any bits are set in either values field but not in the
corresponding mask, a
Match

If present, the
groupsWrap
field specifies the treatment of out-of-range keyboard groups, as described in
Key Symbol Map. If the
groupsWrap
field does not specify a legal treatment for out-of-range groups, a
Value
error results.
If present, the
affectInternalRealMods
field specifies the set of real modifiers to be changed in the internal
modifier definition and the
internalRealMods
field specifies new values for those modifiers. The
affectInternalVirtualMods
and
internalVirtualMods
fields update the virtual modifier component of the modifier definition that
describes the internal modifiers in the same way. If any bits are set in either
values field but not in the corresponding mask field, a
Match

This request changes the indicated parts of the keyboard specified by
deviceSpec
. With XKB, the effect of a key release is independent of the keyboard mapping
at the time of the release, so this request can be processed regardless of the
logical state of the modifier keys at the time of the request.
The
present
field specifies the keyboard map components contained to be changed. The bits
in
present
affect the interpretation of the other fields as follows:
If
XkbKeyTypesMask
is set in
present
,
firstType
and
nTypes
specify a subset of the key types bound to the keyboard to be changed or
created. The index of the first key type to be changed must be less than or
equal to the unmodified length of the list of key types or a
Value
error results.
If
XkbKeyTypesMask
is set in
present
and
SetMapResizeTypes
is set in
flags
, the server resizes the list of key types bound to the keyboard so that the
last key type specified by this request is the last element in the list. If the
list of key types is shrunk, any existing key definitions that use key types
that eliminated are automatically assigned key types from the list of canonical
key types as described in
Assigning Types To Groups of Symbols for a Key. The list of key types
bound to a keyboard must always include the four canonical types and cannot
have more than
XkbMaxTypesPerKey
(32) types; any attempt to reduce the number of types bound to a keyboard
below four or above
XkbMaxTypesPerKey
causes a
Value
error. Symbolic names for newly created key types or levels within a key type
are initialized to
None
.
If
XkbKeyTypesMask
is set in
present
, the types list has
nTypes
entries of type KB_KEYTYPE.Each key type specified in
types
must be valid or a
Value
error results. To be valid a key type definition must meet the following
criteria:
The
numLevels
for the type must be greater than zero.
If the key type is
ONE_LEVEL
(i.e. index zero in the list of key types),
numLevels
must be one.
If the key type is
TWO_LEVEL
or
KEYPAD
, or
ALPHABETIC
(i.e. index one, two, or three in the lest of key types) group width must be
two.
Each key type in types must also be internally consistent, or a Match error
results. To be internally consistent, a key type definition must meet the
following criteria:
Each map entry must specify a resulting level that is legal for the
type.
Any real or virtual modifiers specified in any of the map entries must
also be specified in the
mods
for the type.
If
XkbKeySymsMask
is set in
present
,
firstKeySym
and
nKeySyms
specify a subset of the keyboard keys to which new symbols are to be assigned
and
totalSyms
specifies the total number of symbols to be assigned to those keys. If any of
the keys specified by
firstKeySym
and
nKeySyms
are not legal, a
Match
error results. The
syms
list has
nKeySyms
elements of type KB_KEYSYMMAP. Each key in the resulting key symbol map must
be valid and internally consistent or a
Value
error results. To be valid and internally consistent, a key symbol map must
meet the following criteria:
The key type indices must specify legal result key types.
The number of groups specified by
groupInfo
must be in the range
0…4
.
The
width
of the key symbol map must be equal to
numLevels
of the widest key type bound to the key.
The number of symbols,
nSyms
, must equal the number of groups times
width
.
If
XkbKeyActionsMask
is set in
present
,
firstKeyAction
and
nKeyActions
specify a subset of the keyboard keys to which new actions are to be assigned
and
totalActions
specifies the total number of actions to be assigned to those keys. If any of
the keys specified by
firstKeyAction
and
nKeyActions
are not legal, a
Match
error results. The
count
field of the
actions
return value has
nKeyActions
elements of type CARD8; each element of
count
specifies the number of actions bound to the corresponding key. The
actions
list in the
actions
field has
totalActions
elements of type KB_ACTION. These actions are assigned to each target key in
turn, as specified by
count
. The list of actions assigned to each key must either be empty or have exactly
as many actions as the key has symbols, or a
Match
error results.
If
XkbKeyBehaviorsMask
is set in
present
,
firstKeyBehavior
and
nKeyBehaviors
specify a subset of the keyboard keys to which new behaviors are to be
assigned, and
totalKeyBehaviors
specifies the total number of keys in that range to be assigned non-default
behavior. If any of the keys specified by
firstKeyBehavior
and
nKeyBehaviors
are not legal, a
Match
error results. The
behaviors
list has
totalKeyBehaviors
elements of type KB_BEHAVIOR; each entry of
behaviors
specifies a key in the specified range and a new behavior for that key; any
key that falls in the range specified by
firstBehavior
and
nBehaviors
for which no behavior is specified in
behaviors
is assigned the default behavior,
KB_Default
. The new behaviors must be legal, or a
Value
error results. To be legal, the behavior specified in the
XkbSetMap
request must:
Specify a key in the range indicated by
firstKeyBehavior
and
nKeyBehaviors
.
Not specify the
permanent
flag; permanent behaviors cannot be set or changed using the
XkbSetMap
request.
If present, the
KB_Overlay1
and
KB_Overlay2
behaviors must specify a keycode for the overlay key that is valid for the
current keyboard.
If present, the
KB_RadioGroup
behavior must specify a legal index (0…31) for the radio group to which the
key belongs.
Key behaviors that are not recognized by the server are accepted but ignored.
Attempts to replace a "permanent" behavior are silently ignored; the behavior
is not replaced, but not error is generated and any other components specified
in the
XkbSetMap
request are updated, as appropriate.
If
XkbVirtualModsMask
is set in
present
,
virtualMods
is a mask which specifies the virtual modifiers to be rebound. The
vmods
list specifies the real modifiers that are bound to each of the virtual
modifiers specified in
virtualMods
, starting from the lowest numbered virtual modifier and progressing upward.
Any virtual modifier that is not specified in
virtualMods
has no corresponding entry in
vmods
, so the
vmods
list has one entry for each bit that is set in
virtualMods
.
If
XkbExplicitComponentsMask
is set in
present
,
firstKeyExplicit
and
nKeyExplicit
specify a subset of the keyboard keys to which new explicit components are to
be assigned, and
totalKeyExplicit
specifies the total number of keys in that range that have at least one
explicit component. The
explicit
list has
totalKeyExplicit
elements of type KB_KEYEXPLICIT; each entry of
explicit
specifies a key in the specified range and a new set of explicit components
for that key. Any key that falls in the range specified by
firstKeyExplicit
and
nKeyExplicit
that is not assigned some value in
explicit
has no explicit components.
If
XkbModifierMapMask
is set in
present
,
firstModMapKey
and
nModMapKeys
specify a subset of the keyboard keys for which new modifier mappings are to
be assigned, and
totalModMapKeys
specifies the total number of keys in that range to which at least one
modifier is bound. The
modmap
list has
totalModMapKeys
elements of type KB_KEYMODMAP; each entry of
modmap
specifies a key in the specified range and a new set of modifiers to be
associated with that key. Any key that falls in the range specified by
firstModMapKey
and
nModMapKeys
that is not assigned some value in
modmap
has no associated modifiers.
If the modifier map is changed by the
XkbSetMap
request, any changes are also reflected in the core protocol modifier mapping.
Changes to the core protocol modifier mapping are reported to XKB-unaware
clients via
MappingNotify
events and can be retrieved with the core protocol
GetModifierMapping
request.
If
XkbVirtualModMapMask
is set in
present
,
firstVModMapKey
and
nVModMapKeys
specify a subset of the keyboard keys for which new modifier mappings are to
be assigned, and
totalVModMapKeys
specifies the total number of keys in that range to which at least one virtual
modifier is bound. The
vmodmap
list has
totalVModMapKeys
elements of type KB_KEYVMODMAP; each entry of
vmodmap
specifies a key in the specified range and a new set of virtual modifiers to
be associated with that key. Any key that falls in the range specified by
firstVModMapKey
and
nVModMapKeys
that is not assigned some value in
vmodmap
has no associated virtual modifiers.
If the resulting keyboard map is legal, the server updates the keyboard map.
Changes to some keyboard components have indirect effects on others:
If the
XkbSetMapRecomputeActions
bit is set in
flags
, the actions associated with any keys for which symbol or modifier bindings
were changed by this request are recomputed as described in
Assigning Actions To Keys. Note
that actions are recomputed
after
any actions specified in this request are bound to keys, so the actions
specified in this request might be clobbered by the automatic assignment of
actions to keys.
If the group width of an existing key type is changed, the list of symbols
associated with any keys of the changed type might be resized accordingly. If
the list increases in size, any unspecified new symbols are initialized to
NoSymbol
.
If the list of actions associated with a key is not empty, changing the key
type of the key resizes the list. Unspecified new actions are calculated by
applying any keyboard symbol interpretations to the corresponding symbols.
The number of groups global to the keyboard is always equal to the largest
number of groups specified by any of the key symbol maps. Changing the number
of groups in one or more key symbol maps may change the number of groups global
to the keyboard.
Assigning key behavior
KB_RadioGroup
to a key adds that key as a member of the specified radio group. Changing a
key with the existing behavior
KB_RadioGroup
removes that key from the group. Changing the elements of a radio group can
cause synthetic key press or key release events if the key to be added or
removed is logically down at the time of the change.
Changing a key with behavior
KB_Lock
causes a synthetic key release event if the key is logically but not
physically down at the time of the change.
This request sends an
XkbMapNotify
event which reflects both explicit and indirect map changes to any interested
clients. If any symbolic names are changed, it sends a
XkbNamesNotify
reflecting the changes to any interested clients. XKB-unaware clients are
notified of keyboard changes via core protocol
MappingNotify
events.
Key press and key release events caused by changing key behavior may cause
additional
XkbStateNotify
or
XkbIndicatorStateNotify
events.

device or a feedback class and identifier other than the defaults, and the
server does not support indicator names or indicator maps for extension
devices, the
supported
return value is
False
and the values of the other fields in the reply are undefined. If the client
which issued the unsupported request has also selected to do so, it will also
receive an
XkbExtensionDeviceNotify
event which reports the attempt to use an unsupported feature, in this case
one or both of
XkbXI_IndicatorMaps
and
XkbXI_IndicatorNames
.
Otherwise,
supported

True
and the

0
if the server does not support the input extension. The
indicator
return value reports the name for which information was requested and the
found
return value is
True
if an indicator with the specified name was found on the device.
If no indicator with the specified name is found on the specified device, and
the
createMap
field is
True
, XKB assigns the specified name to the lowest-numbered indicator that has no
name (i.e. whose name is
None
) and applies the rest of the fields in the request to the newly named
indicator. If no unnamed indicators remain, this request reports no error and
has no effect.
If no matching indicator is found or new indicator assigned this request
reports no error and has no effect. Otherwise, it updates the indicator as
follows:
If
setMap
is
True
, XKB changes the map for the indicator (see Indicator Maps) to reflect the
values specified in
map
.
If
setState
is
True
, XKB attempts to explicitly change the state of the indicator to the state
specified in
on
. The effects of an attempt to explicitly change the state of an indicator
depend on the values in the map for that indicator and are not guaranteed to
succeed.
If this request affects both indicator map and state, it updates the indicator
map before attempting to change its state, so the success of the explicit
change depends on the indicator map values specified in the request.
If this request changes the indicator map, it applies the new map immediately
to determine the appropriate state for the indicator given the new indicator
map and the current state of the keyboard.

mask specifies the groups for which names are defined; any groups not
specified in
groupNames
have the name
None
. The list of group names in
valueList
contains the names of the listed groups, beginning with the lowest-numbered
group for which a name is defined and proceeding to the highest.
If key names are reported, the
firstKey

fields specify the components to be changed; the type of each
valueList
entry, the order in which components appear in the
valueList
when specified, and the correspondence between components in
which
and the entries in the
valueList
are as specified for the
XkbGetNames
request.
If keycodes, geometry, symbols, physical symbols, types or compatibility map
names are to be changed, the corresponding entries in the
valueList
must have the value
None
or specify a valid ATOM, else an
Atom
error occurs.
If key type names are to be changed, the
firstType

nTypes
fields specify a range of types for which new names are supplied, and the list
of key type names in
valueList
has
nTypes
elements. Names for types that fall outside of the range specified by
firstType
and
nTypes
are not affected. If this request specifies names for types that are not
present on the keyboard, a
Match
error results. All of the type names in the
valueList
must be valid ATOMs or have the value
None
, or an
Atom

The names of the first four keyboard types are specified by the XKB extension
and cannot be changed; including any of the canonical types in this request
causes an
Access
error, as does trying to assign the name reserved for a canonical type to one
of the other key types.
If key type level names are to be changed, the
firstKTLevel
and
nKTLevels
fields specify a range of key types for which new level names are supplied,
and the list of key type level names in the
valueList
has two parts: The
count
array has
nKTLevels
elements, each of which specifies the number of levels for which names are
supplied on the corresponding key type; any levels for which no names are
specified are assigned the name
None
. The
names
array has
totalKTLevels
atoms and specifies the names of each type sequentially. The
totalKTLevels
field must always equal the sum of all of the elements of the
count
array. Level names for types that fall outside of the specified range are not
affected. If this request specifies level names for types that are not present
on the keyboard, or if it specifies more names for a type than the type has
levels, a
Match
error results. All specified type level names must be
None
or a valid ATOM or an
Atom

If indicator names are to be changed, the
indicators
mask specifies the indicators for which new names are specified; the names for
indicators not specified in
indicators
are not affected. The list of indicator names in

If group names are to be changed, the
groupNames
mask specifies the groups for which new names are specified; the name of any
group not specified in
groupNames
is not changed. The list of group names in
valueList
contains the new names for the listed groups, beginning with the
lowest-numbered group for which a name is defined and proceeding to the
highest. All specified group names must be a valid ATOM or

nKeys
fields specify a range of keys for which new names are defined; the name of
any key that does not fall in the range specified by
firstKey
and
nKeys
is not changed. The list of key names in the

If key aliases are to be changed, the
nKeyAliases
field specifies the length of a new list of key aliases for the keyboard. The
list of key aliases can only be replaced in its entirety; it cannot be
replaced. The list of key aliases in
valueList
has
nKeyAliases
entries, each of which reports an alias and the real name of the key to which
it corresponds.
XKB does not check key names or aliases for consistency and validity, so
applications should take care not to assign duplicate names or aliases
If radio group names are to be changed, the
nRadioGroups
field specifies the length of a new list of radio group names for the
keyboard. There is no way to edit the list of radio group names; it can only be
replaced in its entirety. The list of radio group names in
valueList
reports the names of each group and has
nRadioGroups

This request changes the reported description of the geometry for the keyboard
specified by
deviceSpec
. If deviceSpec does not specify a valid keyboard device, a

The
name
field specifies the name of the new keyboard geometry and must be a valid ATOM
or an
Atom
error results. The new geometry is not added to the server database of
keyboard components, but it can be retrieved using the
XkbGetGeometry
request for as long as it is bound to the keyboard. The keyboard geometry
symbolic name is also updated from the name field, and an
XkbNamesNotify
event is generated, if necessary.
The list of
colors
must include at least two definitions, or a
Value
error results. All color definitions in the geometry must specify a legal
color (i.e. must specify a valid index for one of the entries of the
colors
list) or a
Match
error results. The
baseColorNdx
and the
labelColorNdx
must be different or a
Match
error results.
The list of
shapes
must include at least one shape definition, or a
Value
error results. If any two shapes have the same name, a
Match
error result. All doodads and keys which specify shape must specify a valid
index for one of the elements of the
shapes
list, or a
Match
error results.
All section, shape and doodad names must be valid ATOMs or an
Atom
error results; the constant
None
is not permitted for any of these components.
All doodads must be of a known type; XKB does not support "private" doodad
types.
If, after rotation, any keys or doodads fall outside of the bounding box for a
section, the bounding box is automatically adjusted to the minimum size which
encloses all of its components.
If, after adjustment and rotation, the bounding box of any section or doodad
extends below zero on either the X or Y axes, the entire geometry is translated
so that the minimum extent along either axis is zero.
If, after rotation and translation, any keyboard components fall outside of the
rectangle specified by
widthMM
and
heightMM
, the keyboard dimensions are automatically resized to the minimum bounding box
that surrounds all components. Otherwise, the width and height of the keyboard
are left as specified.
The
under
field of any overlay key definitions must specify a key that is in the section
that contains the overlay key, or a
Match
error results. This request does not check the value of the
over
field of an overlay key definition, so applications must be careful to avoid
conflicts with actual keys.
This request does not verify that key names or aliases are unique. It also does
not verify that all key names specified in the geometry are bound to some
keycode or that all keys that are named in the keyboard definition are also
available in the geometry. Applications should make sure that keyboard geometry
has no internal conflicts and is consistent with the other components of the
keyboard definition, but XKB does not check for or guarantee it.

Each pattern uses the ISO Latin-1 encoding and should contain only parentheses,
the wildcard characters "?" and "*" or characters that are permitted in a
component class or member name (see Component Names). Illegal
characters in a pattern are simply ignored; no error results if a pattern
contains illegal characters.
Comparison is case-sensitive and, in a pattern, the "?" wildcard character
matches any single character except parentheses while the "*" character matches
any number of characters except parentheses. If an implementation accepts
characters other than those required by XKB, whether or not those characters
match either wildcard is also implementation dependent. An empty pattern does
not match any component names.
On successful return, the

fields can include any combinations of these
XkbGetMapByName
(GBN) components:

If either field contains a GBN component that depends on some database
component for which the request does not supply an expression, XKB
automatically substitutes the special pattern "%" which copies the
corresponding component from the current keyboard description, as described in
Partial Components and Combining
Multiple Components.
The
load
flag asks the server to replace the current keyboard description for
deviceSpec
with the newly constructed keyboard description. If
load
is
True
, the request must include component expressions for all of the database
components; if any are missing, XKB substitutes "%" as described above.
If all necessary components are both specified and found, the new keyboard
description is loaded. If the new keyboard description has a different geometry
or keycode range than the previous keyboard description, XKB sends
XkbNewKeyboardNotify
events to all interested clients. See
Replacing the Keyboard
"On-the-Fly" for more information about the effects of replacing the
keyboard description on the fly.
If the range of keycodes changes, clients that have requested
XkbNewKeyboardNotify
events are not sent any other change notification events by this request.
Clients that do not request
XkbNewKeyboardNotify
events are sent other XKB change notification events (e.g.
XkbMapNotify
,
XkbNamesNotify
) as necessary to alert them to as many of the keyboard changes as possible.
If no error occurs, the request reply reports the GBN components that were
found and sends a description of any of the resulting keyboard that includes
and of the components that were requested.
The
deviceID
return value reports the X Input extension device identifier of the keyboard
that was used, or
0
if the server does not support the X input extension.
The
minKeyCode
and
maxKeyCode
return values report the legal range of keycodes for the keyboard description
that was created. If the resulting keyboard description does not include at
least one of the key names, client symbols or server symbols components,
minKeyCode
and
maxKeyCode
are both
0
.
The
loaded
return value reports whether or not the existing keyboard definition was
replaced with the newly created one. If
loaded
is
True
, the
newKeyboard
return value reports whether or not the new map changed the geometry or range
of keycodes and caused
XkbNewKeyboardNotify
events for clients that have requested them.
The
found
return value reports the GBN components that were present in the keymap that
was constructed by this request. The
reported
return value lists the subset of those components for which descriptions
follow. if any of the components specified in the
need
field of the request were not found,
reported
is empty, otherwise it contains the intersection of the
found
return value with the union of the
need
and
want
request fields.
If any of
GBN_Types
,
GBN_ClientSymbols
or
GBN_ServerSymbols
are set in
reported
, the
map
return value has the same format as the reply to an
XkbGetMap
request and reports the corresponding pieces of the newly constructed keyboard
description.
If
GBN_CompatMap
is set in
reported
, the
compat
return value has the same format as the reply to an
XkbGetCompatMap
request and reports the symbol interpretations and group compatibility map for
the newly constructed keyboard description.
If
GBN_IndicatorMap
is set in
reported
, the
indicators
return value has the same format as the reply to an
XkbGetIndicatorMap
request and reports the physical indicators and indicator maps for the newly
constructed keyboard description.
If
GBN_KeyNames
or
GBN_OtherNames
are set in
reported
, the
names
return value has the same format as the reply to an
XkbGetNames
reply and reports the corresponding set of symbolic names for the newly
constructed keyboard description.
If
GBN_Geometry
is set in
reported
, the
geometry
return value has the same format as the reply to an
XkbGetGeometryMap
request and reports the keyboard geometry for the newly constructed keyboard
description.

Reports a subset of the XKB-supplied information about the input device
specified by
deviceSpec
. Unlike most XKB requests, the device specified for
XkbGetDeviceInfo
need not be a keyboard device. Nonetheless, a
Keyboard
error results if
deviceSpec
does not specify a valid core or input extension device.
The
wanted
field specifies the types of information to be returned, and controls the
interpretation of the other request fields.
If the server does not support assignment of XKB actions to extension device
buttons, the
allButtons
,
firstButton
and
nButtons
fields are ignored.
Otherwise, if the
XkbXI_ButtonActions
flag is set in
wanted
, the
allButtons
,
firstButton
and
nButtons
fields specify the device buttons for which actions should be returned.
Setting
allButtons
to
True
requests actions for all device buttons; if
allButtons
is
False
,
firstButton
and
nButtons
specify a range of buttons for which actions are requested. If the device has
no buttons or if
firstButton
and
nButtons
specify illegal buttons, a
Match
error results. If
allButtons
is
True
,
firstButton
and
nButtons
are ignored.
If the server does not support XKB access to any aspect of the indicators on
extension devices, or if the
wanted
field does not include any of the indicator flags, the
ledClass
and
ledID
fields are ignored. Otherwise,
ledClass
and
ledID
specify one or more feedback(s) for which indicator information is requested.
If
ledClass
or
ledID
have illegal values, a
Value
error results. If they have legal values but do not specify a keyboard or
indicator class feedback for the device in question, a
Match
error results.
The
ledClass
field can specify either
KbdFeedbackClass
,
LedFeedbackClass
,
XkbDfltXIClass
, or
XkbAllXIClasses
. If at least one keyboard feedback is defined for the specified device,
XkbDfltXIClass
is equivalent to
KbdFeedbackClass
, otherwise it is equivalent to
LedFeedbackClass
. If
XkbAllXIClasses
is specified, this request returns information about both indicator and
keyboard class feedbacks which match the requested identifier, as described
below.
The
ledID
field can specify any valid input extension feedback identifier,
XkbDfltXIId
, or
XkbAllXIIds
. The default keyboard feedback is the one that is affected by core protocol
requests; the default led feedback is implementation-specific. If
XkbAllXIIds
is specified, this request returns indicator information about all feedbacks
of the class(es) specified by
ledClass
.
If no error results, the
deviceID
return value reports the input extension device identifier of the device for
which values are being returned. The
supported
return value reports the set of optional XKB extension device features that
are supported by this implementation (see
Interactions Between XKB and the X Input
Extension) for the specified device, and the unsupported return value
reports any
unsupported
features.
If
hasOwnState
is
True
, the device is also a keyboard, and any indicator maps bound to the device use
the current state and control settings for this device to control automatic
changes. If
hasOwnState
is
False
, the state and control settings of the core keyboard device control automatic
indicator changes.
The
name
field reports the X Input Extension name for the device. The
devType
field reports the X Input Extension device type. Both fields are provided
merely for convenience and are not interpreted by XKB.
The
present
return value reports the kinds of device information being returned, and
controls the interpretation of the remaining fields. The
present
field consists of the
wanted
field from the original request minus the flags for any unsupported features.
If
XkbXI_ButtonActions
is set in
present
, the
totalBtns
return value reports the total number of buttons present on the device,
firstBtnWanted
and
nBtnsWanted
specify the range of buttons for which actions were requested, and the
firstBtnRtrn
and
nBtnsRtrn
values specify the range of buttons for which actions are reported. The
actionsRtrn
list has
nButtonsRtrn
entries which contain the actions bound to the specified buttons on the
device. Any buttons for which actions were requested but not returned have the
action
NoAction()
.
If any indicator information is reported, the leds list contains one element
for each requested feedback. For example, if
ledClass
is
XkbAllXIClasses
and
ledID
is
XkbAllXIIds
,
leds
describes all of the indicators on the device and has one element for each
keyboard or led class feedback defined for the device. If any information at
all is reported about a feedback, the set of physical indicators is also
reported in the
physIndicators
field of the corresponding element of
leds
.
If the server supports assignment of indicator maps to extension device
indicators, and if the
XkbXI_IndicatorMaps
flag is set in
wanted
, each member of
leds
reports any indicators on the corresponding feedback to which names have been
assigned. Any indicators for which no map is reported have the default map,
which allows explicit changes and does not request any automatic changes.
If the server supports assignment of indicator names to extension device
indicators, and the
XkbXI_IndicatorNames
flag is set in
wanted
, each member of
leds
reports any indicators on the corresponding feedback to which names have been
assigned. Any indicators for which no name is reported have the name
None
.
If the server supports XKB access to the state of extension device indicators,
and the
XkbXI_IndicatorState
flag is set in wanted, each member of leds reports the state of the indicators
on the corresponding feedback.
If any unsupported features are requested, and the requesting client has
selected for them, the server sends the client an
XkbExtensionDeviceNotify
event which indicates that an unsupported feature was requested. This event is
only generated if the client which issued the unsupported request has selected
for it and, if generated, is not sent to any other clients.

fields are ignored.
Otherwise, if the
XkbXI_ButtonActions

nBtns
fields specify a range of buttons for which actions are specified in this
request. If the device has no buttons or if
firstBtn
and
nBtns
specify illegal buttons, a
Match
error results.
Each element of the
leds
list describes the changes for a single keyboard or led feedback. If the
ledClass
field of any element of
leds
contains any value other than
KbdFeedbackClass
,
LedFeedbackClass
or
XkbDfltXIClass
, a
Value
error results. If the
ledId
field of any element of leds contains any value other than a valid input
extension feedback identifier or
XkbDfltXIId
, a
Value
error results. If both fields are valid, but the device has no matching
feedback, a
Match
error results.
The fields of each element of
leds
are interpreted as follows:
If
XkbXI_IndicatorMaps
is set in
change
and the server supports XKB assignment of indicator maps to the corresponding
feedback, the maps for all indicators on the corresponding feedback are taken
from
leds
. If the server does not support this feature, any maps specified in
leds
are ignored.
If
XkbXI_IndicatorNames
is set in
change
, and the server supports XKB assignment of names to indicators for the
corresponding feedback, the names for all indicators on the corresponding
feedback are taken from
leds
. If the server does not support this feature, any names specified in
leds
are ignored. Regardless of whether they are used, any names be a valid Atom or
None
, or an
Atom
error results.
If
XkbXI_IndicatorState
is set in change, and the server supports XKB changes to extension device
indicator state, the server attempts to change the indicators on the
corresponding feedback as specified by
leds
. Any indicator maps bound to the feedback are applied, so state changes might
be blocked or have side-effects.
If any unsupported features are requested, and the requesting client has
selected for them, the server sends the client an
XkbExtensionDeviceNotify
event which indicates that an unsupported feature was requested. This event is
only generated if the client which issued the unsupported request has selected
for it and, if generated, is not sent to any other clients.
Debugging the X Keyboard ExtensionXkbSetDebuggingFlagsaffectFlags, flags: CARD32
affectCtrls, ctrls: CARD32
message: STRING
currentFlags, supportedFlags: CARD32
currentCtrls, supportedCtrls: CARD32
This request sets up various internal XKB debugging flags and controls. It is
intended for developer use and may be disabled in production servers. If
disabled,
XkbSetDebuggingFlags
has no effect but returns
Success
.
The
affectFlags
field specifies the debugging flags to be changed, the
flags
field specifies new values for the changed flags. The interpretation of the
debugging flags is implementation-specific, but flags are intended to control
debugging output and should not otherwise affect the operation of the server.
The
affectCtrls
field specifies the debugging controls to be changed, the
ctrls
field specifies new values for the changed controls. The interpretation of the
debugging controls is implementation-specific, but debugging controls are
allowed to affect the behavior of the server.
The
message
field provides a message that the X server can print in any logging or
debugging files before changing the flags. The server must accept this field
but it is not required to actually display it anywhere.
The X Test Suite makes some assumptions about the implementation of locking
modifier keys that do not apply when XKB is present. The
XkbDF_DisableLocks
debugging control provides a simple workaround to these test suite problems by
simply disabling all locking keys. If
XkbDF_DisableLocks
is enabled, the
SA_LockMods
and
SA_LockGroup
actions behave like
SA_SetMods
and
SA_LockMods
, respectively. If it is disabled,
SA_LockMods
and
SA_LockGroup
actions behave normally.
Implementations are free to ignore the
XkbDF_DisableLocks
debugging control or to define others.
The
currentFlags
return value reports the current setting for the debugging flags, if
applicable. The
currentCtrls
return value reports the setting for the debugging controls, if applicable.
The
supportedFlags
and
supportedCtrls
fields report the flags and controls that are recognized by the
implementation. Attempts to change unsupported fields or controls are silently
ignored.
If the
XkbSetDebuggingFlags
request contains more data than expected, the server ignores the extra data,
but no error results. If the request has less data than expected, a
Length
error results.
If the
XkbSetDebuggingFlags
reply contains more data than expected, the client just ignores any
uninterpreted data without reporting an error. If the reply has less data than
expected, a
Length
error results.
Events
All XKB events report the time at which they occurred in a field named
time
and the device on which they occurred in a field named
deviceID
. XKB uses a single X event code for all events and uses a common field to
distinguish XKB event type.
Tracking Keyboard ReplacementXkbNewKeyboardNotifytime: TIMESTAMP

changed: KB_NKNDETAILMASK
minKeyCode, maxKeyCode: KEYCODE
oldDeviceID: CARD8
oldMinKeyCode, oldMaxKeyCode: KEYCODE
requestMajor, requestMinor: CARD8
An
XkbNewKeyboardNotify
event reports that a new core keyboard has been installed. New keyboard notify
events can be generated:
When the X server detects that the keyboard was changed.
When a client installs a new extension device as the core keyboard
using the X Input Extension
ChangeKeyboardDevice
request.
When a client issues an
XkbGetMapByName
request which changes the keycodes range or geometry.
The
changed
field of the event reports the aspects of the keyboard that have changed, and
can contain any combination of the event details for this event:
Bit in ChangedMeaningNKN_KeycodesThe new keyboard has a different minimum or maximum keycode.NKN_GeometryThe new keyboard has a different keyboard geometry.NKN_DeviceIDThe new keyboard has a new X Input Extension device
identifier
The server sends an
XkbNewKeyboardNotify
event to a client only if at least one of the bits that is set in the
changed
field of the event is also set in the appropriate event details mask for the
client.
The
minKeyCode
and
maxKeyCode
fields report the minimum and maximum keycodes that can be returned by the new
keyboard. The
oldMinKeyCode
and
oldMaxKeyCode
fields report the minimum and maximum values that could be returned before the
change. This event always reports all four values, but the old and new values
are the same unless
NKN_Keycodes
is set in
changed
.
Once a client receives a new keyboard notify event which reports a new keycode
range, the X server reports events from all keys in the new range to that
client. Clients that do not request or receive new keyboard notify events
receive events only from keys that fall in the last range for legal keys
reported to that client. See
Replacing the Keyboard "On-the-Fly" for a more detailed explanation.
If
NKN_Keycodes
is set in
changed
, the
XkbNewKeyboardNotify
event subsumes all other change notification events (e.g.
XkbMapNotify
,
XkbNamesNotify
) that would otherwise result from the keyboard change. Clients who receive an
XkbNewKeyboardNotify
event should assume that all other aspects of the keyboard mapping have
changed and regenerate the entire local copy of the keyboard description.
The
deviceID
field reports the X Input Extension device identifier of the new keyboard
device;
oldDeviceID
reports the device identifier before the change. This event always includes
both values, but they are the same unless
NKN_DeviceID
is set in
changed
. If the server does not support the X Input Extension, both fields have the
value
0
.
The
requestMajor
and
requestMinor
fields report the major and minor opcode of the request that caused the
keyboard change. If the keyboard change was not caused by some client request,
both fields have the value
0
.

An
XkbMapNotify
event reports that some aspect of XKB map for a keyboard has changed. Map
notify events can be generated whenever some aspect of the keyboard map is
changed by an XKB or core protocol request.
The
deviceID
field reports the keyboard for which some map component has changed and the
changed
field reports the components with new values, and can contain any of the
values that are legal for the
full
and
partial
fields of the
XkbGetMap
request. The server sends an
XkbMapNotify
event to a client only if at least one of the bits that is set in the

client.
The
minKeyCode

An XkbStateNotify
event reports that some component of the XKB state (see
Keyboard State) has changed.
State notify events are usually caused by key or pointer activity, but they can
also result from explicit state changes requested by the
XkbLatchLockState
request or by other extensions.
The

The server sends an
XkbStateNotify
event to a client only if at least one of the bits that is set in the
changed
field of the event is also set in the appropriate event details mask for the
client.
A state notify event reports current values for all state components, even
those with unchanged values.
The
keycode
field reports the key or button which caused the change in state while the
eventType
field reports the exact type of event (e.g.
KeyPress
). If the change in state was not caused by key or button activity, both fields
have the value
0
.
The
requestMajor
and
requestMinor
fields report the major and minor opcodes of the request that caused the
change in state and have the value
0
if it was resulted from key or button activity.

An
XkbControlsNotify
event reports a change in one or more of the global keyboard controls (see
Global Keyboard Controls)
or in the internal modifiers or ignore locks masks (see
Server Internal Modifiers and Ignore
Locks Behavior). Controls notify events are usually caused by and
XkbSetControls
request, but they can also be caused by keyboard activity or certain core
protocol and input extension requests.
The
deviceID
field reports the keyboard for which some control has changed, and the
changed
field reports the controls that have new values.
The
changed
field can contain any of the values that are permitted for the
changeControls
field of the
XkbSetControls
request. The server sends an
XkbControlsNotify
event to a client only if at least one of the bits that is set in the
changed
field of the event is also set in the appropriate event details mask for the
client.
The
numGroups
field reports the total number of groups defined for the keyboard, whether or
not the number of groups has changed.
The
enabledControls
field reports the current status of all of the boolean controls, whether or
not any boolean controls changed state. If
EnabledControls
is set in
changed
, the
enabledControlChanges
field reports the boolean controls that were enabled or disabled; if a control
is specified in
enabledControlChanges
, the value that is reported for that control in
enabledControls
represents a change in state.
The
keycode
field reports the key or button which caused the change in state while the
eventType
field reports the exact type of event (e.g.
KeyPress
). If the change in state was not caused by key or button activity, both fields
have the value
0
.
The
requestMajor
and
requestMinor
fields report the major and minor opcodes of the request that caused the
change in state and have the value
0
if it was resulted from key or button activity.
Tracking Keyboard Indicator State ChangesXkbIndicatorStateNotifytime: TIMESTAMP
deviceID: CARD8
stateChanged, state: KB_INDICATORMASK
An
XkbIndicatorStateNotify
event indicates that one or more of the indicators on a keyboard have changed
state. Indicator state notify events can be caused by:
Automatic update to reflect changes in keyboard state (keyboard
activity,
XkbLatchLockState
requests).
Automatic update to reflect changes in keyboard controls (
XkbSetControls
, keyboard activity, certain core protocol and input extension requests).
Explicit attempts to change indicator state (core protocol and input
extension requests,
XkbSetNamedIndicator
requests).
Changes to indicator maps (
XkbSetIndicatorMap
and
XkbSetNamedIndicator
requests).
The
deviceID
field reports the keyboard for which some indicator has changed, and the
state
field reports the new state for all indicators on the specified keyboard. The
stateChanged
field specifies which of the values in
state
represent a new state for the corresponding indicator. The server sends an
XkbIndicatorStateNotify
event to a client only if at least one of the bits that is set in the
stateChanged
field of the event is also set in the appropriate event details mask for the
client.
Tracking Keyboard Indicator Map ChangesXkbIndicatorMapNotifytime: TIMESTAMP
deviceID: CARD8
state: KB_INDICATORMASK
mapChanged: KB_INDICATORMASK
An
XkbIndicatorMapNotify
event indicates that the maps for one or more keyboard indicators have been
changed. Indicator map notify events can be caused by
XkbSetIndicatorMap
and
XkbSetNamedIndicator
requests.
The
deviceID
field reports the keyboard for which some indicator map has changed, and the
mapChanged
field reports the indicators with changed maps. The server sends an
XkbIndicatorMapNotify
event to a client only if at least one of the bits that is set in the
mapChanged
field of the event is also set in the appropriate event details mask for the
client.
The
state
field reports the current state of all indicators on the specified keyboard.

changedIndicators: KB_INDICATORMASK
An
XkbNamesNotify
event reports a change to one or more of the symbolic names associated with a
keyboard. Symbolic names can change when:
Some client explicitly changes them using
XkbSetNames
.
The list of key types or radio groups is resized
The group width of some key type is changed
The
deviceID
field reports the keyboard on which names were changed. The
changed
mask lists the components for which some names have changed and can have any
combination of the values permitted for the
which
field of the
XkbGetNames
request. The server sends an
XkbNamesNotify
event to a client only if at least one of the bits that is set in the
changed
field of the event is also set in the appropriate event details mask for the
client.
If
KeyTypeNames
is set in
changed
, the
firstType
and
nTypes
fields report a range of types that includes all types with changed names.
Otherwise, both fields are
0
.
If
KTLevelNames
is set in
changed
, the
firstLevelName
and
nLevelNames
fields report a range of types that includes all types with changed level
names. Otherwise, both fields are
0
.
If
IndicatorNames
is set in
changed
, the
changedIndicators
field reports the indicators with changed names. Otherwise,
changedIndicators
is
0
.
If
VirtualModNames
is set in
changed
, the
changedVirtualMods
field reports the virtual modifiers with changed names. Otherwise,
changedVirtualMods
is
0
.
If
GroupNames
is set in
changed
, the
changedGroupNames
field reports the groups with changed names. Otherwise,
changedGroupNames
is
0
.
If
KeyNames
is set in
changed
, the
firstKey
and
nKeys
fields report a range of keycodes that includes all keys with changed names.
Otherwise, both fields are
0
.
The
nKeyAliases
field reports the total number of key aliases associated with the keyboard,
regardless of whether
KeyAliases
is set in
changed
.
The
nRadioGroups
field reports the total number of radio group names associated with the
keyboard, regardless of whether
RGNames
is set in
changed
.
Tracking Compatibility Map ChangesXkbCompatMapNotifytime: TIMESTAMP
deviceID: CARD8
changedGroups: KB_GROUPMASK
firstSI, nSI: CARD16
nTotalSI: CARD16
An
XkbCompatMapNotify
event indicates that some component of the compatibility map for a keyboard
has been changed. Compatibility map notify events can be caused by
XkbSetCompatMap
and
XkbGetMapByName
requests.
The
deviceID
field reports the keyboard for which the compatibility map has changed; if the
server does not support the X input extension,
deviceID
is
0
.
The
changedGroups
field reports the keyboard groups, if any, with a changed entry in the group
compatibility map. The
firstSI
and
nSI
fields specify a range of symbol interpretations in the symbol compatibility
map that includes all changed symbol interpretations; if the symbol
compatibility map is unchanged, both fields are
0
. The
nTotalSI
field always reports the total number of symbol interpretations present in the
symbol compatibility map, regardless of whether any symbol interpretations have
been changed.
The server sends an
XkbCompatMapNotify
event to a client only if at least one of the following conditions is met:
The
nSI
field of the event is non-zero, and the
XkbSymInterpMask
bit is set in the appropriate event details mask for the client.
The
changedGroups
field of the event contains at least one group, and the
XkbGroupCompatMask
bit is set in the appropriate event details mask for the client.
Tracking Application Bell RequestsXkbBellNotifytime: TIMESTAMP
deviceID: CARD8
bellClass: { KbdFeedbackClass, BellFeedbackClass }
bellID: CARD8
percent: CARD8
pitch: CARD16
duration: CARD16
eventOnly: BOOL
name: ATOM
window: WINDOW
An
XkbBellNotify
event indicates that some client has requested a keyboard bell. Bell notify
events are usually caused by
Bell
,
DeviceBell
, or
XkbBell
requests, but they can also be generated by the server (e.g. if the
AccessXFeedback
control is active).
The server sends an
XkbBellNotify
event to a client if the appropriate event details field for the client has
the value
True
.
The
deviceID
field specifies the device for which a bell was requested, while the
bellClass
and
bellID
fields specify the input extension class and identifier of the feedback for
which the bell was requested. If the reporting server does not support the
input extension, all three fields have the value 0.
The
percent
,
pitch
and
duration
fields report the volume, tone and duration requested for the bell as
specified by the
XkbBell
request. Bell notify events caused by core protocol or input extension
requests use the pitch and duration specified in the corresponding bell or
keyboard feedback control.
If the bell was caused by an
XkbBell
request or by the X server,
name
reports an optional symbolic name for the bell and the
window
field optionally reports the window for which the bell was generated.
Otherwise, both fields have the value
None
.
If the
eventOnly
field is
True
, the server did not generate a sound in response to the request, otherwise the
server issues the beep before sending the event. The eventOnly field can be
True
if the
AudibleBell
control is disabled or if a client explicitly requests
eventOnly
when it issues an
XkbBell
request.
Tracking Messages Generated by Key ActionsXkbActionMessagetime: TIMESTAMP
deviceID: CARD8
keycode: KEYCODE
press: BOOL
mods: KEYMASK
group: KB_GROUP
keyEventFollows: BOOL
message: LISTofCARD8
An
XkbActionMessage
event is generated when the user operates a key to which an
SA_ActionMessage
message is bound under the appropriate state and group. The server sends an
XkbActionMessage
event to a client if the appropriate event details field for the client has
the value
True
.
The
deviceID
field specifies the keyboard device that contains the key which activated the
event. The
keycode
field specifies the key whose operation caused the message and press is
True
if the message was caused by the user pressing the key. The
mods
and
group
fields report the effective keyboard modifiers and group in effect at the time
the key was pressed or released.
If
keyEventFollows
is
True
, the server will also send a key press or release event, as appropriate, for
the key that generated the message. If it is
False
, the key causes only a message. Note that the key event is delivered normally
with respect to passive grabs, keyboard focus, and cursor position, so that
keyEventFollows
does not guarantee that any particular client which receives the
XkbActionMessage
notify event will also receive a key press or release event.
The
message
field is
NULL
-terminated string of up to
ActionMessageLength
(
6
) bytes, which reports the contents of the
message
field in the action that caused the message notify event.
Tracking Changes to AccessX State and KeysXkbAccessXNotifytime: TIMESTAMP
deviceID: CARD8
detail: KB_AXNDETAILMASK
keycode: KEYCODE
slowKeysDelay: CARD16
debounceDelay: CARD16
An
XkbAccessXNotify
event reports on some kinds of keyboard activity when any of the
SlowKeys
,
BounceKeys
or
AccessXKeys
controls are active. Compatibility map notify events can only be caused by
keyboard activity.
The
deviceID
and
keycode
fields specify the keyboard and key for which the event occurred. The
detail
field describes the event that occurred and has one of the following values:
DetailControlMeaning
AXN_SKPress
SlowKeysKey pressed
AXN_SKAccept
SlowKeys
K
ey held until it was accepted.
AXN_SKReject
SlowKeysKey released before it was accepted.
AXN_SKRelease
SlowKeysKey released after it was accepted.
AXN_BKAccept
BounceKeysKey pressed while it was active.
AXN_BKReject
BounceKeysKey pressed while it was still disabled.
AXN_AXKWarning
AccessXKeysShift key held down for four seconds
Each subclass of the AccessX notify event is generated only when the control
specified in the table above is enabled. The server sends an
XkbAccessXNotify
event to a client only if the bit which corresponds to the value of the
detail
field for the event is set in the appropriate event details mask for the
client.
Regardless of the value of
detail
, the
slowKeysDelay
and
debounceDelay
fields always reports the current slow keys acceptance delay (see
The SlowKeys Control) and
debounce delay (see The BounceKeys
Control) for the specified keyboard.

firstButton, nButtons: CARD8
An
XkbExtensionDeviceNotify
event reports:
A change to some part of the XKB information for an extension device.
An attempt to use an XKB extension device feature that is not supported
for the specified device by the current implementation.
The
deviceID
field specifies the X Input Extension device identifier of some device on
which an XKB feature was requested, or
XkbUseCorePtr
if the request affected the core pointer device. The
reason
field explains why the event was generated in response to the request, and can
contain any combination of
XkbXI_UnsupportedFeature
and the values permitted for the change field of the
XkbSetDeviceInfo
request.
If
XkbXI_ButtonActions
is set in
reason
, this event reports a successful change to the XKB actions bound to one or
more buttons on the core pointer or an extension device. The
firstButton
and
nButtons
fields report a range of device buttons that include all of the buttons for
which actions were changed.
If any combination of
XkbXI_IndicatorNames
,
XkbXI_IndicatorMaps
, or
XkbXI_IndicatorState
is set in either
reason
or
unsupported
, the
ledClass
and
ledID
fields specify the X Input Extension feedback class and identifier of the
feedback for which the change is reported. If this event reports any changes to
an indicator feedback, the
ledsDefined
field reports all indicators on that feedback for which either a name or a
indicator map are defined, and
ledState
reports the current state of all of the indicators on the specified feedback.
If
XkbXI_IndicatorNames
is set in
reason
, this event reports a successful change to the symbolic names bound to one or
more extension device indicators by XKB. If
XkbXI_IndicatorMaps
is set in
reason
, this event reports a successful change to the indicator maps bound to one or
more extension device indicators by XKB. If
XkbXI_IndicatorState
is set in reason, this event reports that one or more indicators in the
specified device and feedback have changed state.
If
XkbXI_UnsupportedFeature
is set in reason, this event reports an unsuccessful attempt to use some XKB
extension device feature that is not supported by the XKB implementation in the
server for the specified device. The
unsupported
mask reports the requested features that are not available on the specified
device. See Interactions Between
XKB and the X Input Extension for more information about possible XKB
interactions with the X Input Extension.
The server sends an
XkbExtensionDeviceNotify
event to a client only if at least one of the bits that is set in the
reason
field of the event is also set in the appropriate event details mask for the
client.
Events that report a successful change to some extension device feature are
reported to all clients that have expressed interest in the event; events that
report an attempt to use an unsupported feature are reported only to the client
which issued the request. Events which report a partial success are reported to
all interested clients, but only the client that issued the request is informed
of the attempt to use unsupported features.
