.SH DESCRIPTION
|
|
The
|
|
.ZN XChangeKeyboardMapping
|
|
function defines the symbols for the specified number of KeyCodes
|
|
starting with first_keycode.
|
|
The symbols for KeyCodes outside this range remain unchanged.
|
|
The number of elements in keysyms must be:
|
|
.LP
|
|
.Ds
|
|
num_codes * keysyms_per_keycode
|
|
.De
|
|
.LP
|
|
The specified first_keycode must be greater than or equal to min_keycode
|
|
returned by
|
|
.ZN XDisplayKeycodes ,
|
|
or a
|
|
.ZN BadValue
|
|
error results.
|
|
In addition, the following expression must be less than or equal to
|
|
max_keycode as returned by
|
|
.ZN XDisplayKeycodes ,
|
|
or a
|
|
.ZN BadValue
|
|
error results:
|
|
.LP
|
|
.Ds
|
|
first_keycode + num_codes \- 1
|
|
.De
|
|
.LP
|
|
KeySym number N, counting from zero, for KeyCode K has the following index
|
|
in keysyms, counting from zero:
|
|
.LP
|
|
.Ds
|
|
(K \- first_keycode) * keysyms_per_keycode + N
|
|
.De
|
|
.LP
|
|
The specified keysyms_per_keycode can be chosen arbitrarily by the client
|
|
to be large enough to hold all desired symbols.
|
|
A special KeySym value of
|
|
.ZN NoSymbol
|
|
should be used to fill in unused elements
|
|
for individual KeyCodes.
|
|
It is legal for
|
|
.ZN NoSymbol
|
|
to appear in nontrailing positions
|
|
of the effective list for a KeyCode.
|
|
.ZN XChangeKeyboardMapping
|
|
generates a
|
|
.ZN MappingNotify
|
|
event.
|
|
.LP
|
|
There is no requirement that the X server interpret this mapping.
|
|
It is merely stored for reading and writing by clients.
|
|
.LP
|
|
.ZN XChangeKeyboardMapping
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadValue
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetKeyboardMapping
|
|
function returns the symbols for the specified number of KeyCodes
|
|
starting with first_keycode.
|
|
The value specified in first_keycode must be greater than
|
|
or equal to min_keycode as returned by
|
|
.ZN XDisplayKeycodes ,
|
|
or a
|
|
.ZN BadValue
|
|
error results.
|
|
In addition, the following expression must be less than or equal
|
|
to max_keycode as returned by
|
|
.ZN XDisplayKeycodes :
|
|
.LP
|
|
.Ds
|
|
first_keycode + keycode_count \- 1
|
|
.De
|
|
.LP
|
|
If this is not the case, a
|
|
.ZN BadValue
|
|
error results.
|
|
The number of elements in the KeySyms list is:
|
|
.LP
|
|
.Ds
|
|
keycode_count * keysyms_per_keycode_return
|
|
.De
|
|
.LP
|
|
KeySym number N, counting from zero, for KeyCode K has the following index
|
|
in the list, counting from zero:
|
|
.Ds
|
|
(K \- first_code) * keysyms_per_code_return + N
|
|
.De
|
|
.LP
|
|
The X server arbitrarily chooses the keysyms_per_keycode_return value
|
|
to be large enough to report all requested symbols.
|
|
A special KeySym value of
|
|
.ZN NoSymbol
|
|
is used to fill in unused elements for
|
|
individual KeyCodes.
|
|
To free the storage returned by
|
|
.ZN XGetKeyboardMapping ,
|
|
use
|
|
.ZN XFree .
|
|
.LP
|
|
.ZN XGetKeyboardMapping
|
|
can generate a
|
|
.ZN BadValue
|
|
error.
|
|
.LP
|
|
The
|
|
.ZN XDisplayKeycodes
|
|
function returns the min-keycodes and max-keycodes supported by the
|
|
specified display.
|
|
The minimum number of KeyCodes returned is never less than 8,
|
|
and the maximum number of KeyCodes returned is never greater than 255.
|
|
Not all KeyCodes in this range are required to have corresponding keys.
|
|
.LP
|
|
The
|
|
.ZN XSetModifierMapping
|
|
function specifies the KeyCodes of the keys (if any) that are to be used
|
|
as modifiers.
|
|
If it succeeds,
|
|
the X server generates a
|
|
.ZN MappingNotify
|
|
event, and
|
|
.ZN XSetModifierMapping
|
|
returns
|
|
.ZN MappingSuccess .
|
|
X permits at most 8 modifier keys.
|
|
If more than 8 are specified in the
|
|
.ZN XModifierKeymap
|
|
structure, a
|
|
.ZN BadLength
|
|
error results.
|
|
.LP
|
|
The modifiermap member of the
|
|
.ZN XModifierKeymap
|
|
structure contains 8 sets of max_keypermod KeyCodes,
|
|
one for each modifier in the order
|
|
.ZN Shift ,
|
|
.ZN Lock ,
|
|
.ZN Control ,
|
|
.ZN Mod1 ,
|
|
.ZN Mod2 ,
|
|
.ZN Mod3 ,
|
|
.ZN Mod4 ,
|
|
and
|
|
.ZN Mod5 .
|
|
Only nonzero KeyCodes have meaning in each set,
|
|
and zero KeyCodes are ignored.
|
|
In addition, all of the nonzero KeyCodes must be in the range specified by
|
|
min_keycode and max_keycode in the
|
|
.ZN Display
|
|
structure,
|
|
or a
|
|
.ZN BadValue
|
|
error results.
|
|
.LP
|
|
An X server can impose restrictions on how modifiers can be changed,
|
|
for example,
|
|
if certain keys do not generate up transitions in hardware,
|
|
if auto-repeat cannot be disabled on certain keys,
|
|
or if multiple modifier keys are not supported.
|
|
If some such restriction is violated,
|
|
the status reply is
|
|
.ZN MappingFailed ,
|
|
and none of the modifiers are changed.
|
|
If the new KeyCodes specified for a modifier differ from those
|
|
currently defined and any (current or new) keys for that modifier are
|
|
in the logically down state,
|
|
.ZN XSetModifierMapping
|
|
returns
|
|
.ZN MappingBusy ,
|
|
and none of the modifiers is changed.
|
|
.LP
|
|
.ZN XSetModifierMapping
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadValue
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetModifierMapping
|
|
function returns a pointer to a newly created
|
|
.ZN XModifierKeymap
|
|
structure that contains the keys being used as modifiers.
|
|
The structure should be freed after use by calling
|
|
.ZN XFreeModifiermap .
|
|
If only zero values appear in the set for any modifier,
|
|
that modifier is disabled.
|
|
.LP
|
|
The
|
|
.ZN XNewModifiermap
|
|
function returns a pointer to
|
|
.ZN XModifierKeymap
|
|
structure for later use.
|
|
.LP
|
|
The
|
|
.ZN XInsertModifiermapEntry
|
|
function adds the specified KeyCode to the set that controls the specified
|
|
modifier and returns the resulting
|
|
.ZN XModifierKeymap
|
|
structure (expanded as needed).
|
|
.LP
|
|
The
|
|
.ZN XDeleteModifiermapEntry
|
|
function deletes the specified KeyCode from the set that controls the
|
|
specified modifier and returns a pointer to the resulting
|
|
.ZN XModifierKeymap
|
|
structure.
|
|
.LP
|
