.SH DESCRIPTION
|
|
.LP
|
|
To modify the server's compatibility map, first modify a local copy of the Xkb
|
|
compatibility map, then call
|
|
.I XkbSetCompatMap.
|
|
You may allocate a new compatibility map for this purpose using
|
|
.I XkbAllocCompatMap.
|
|
You may also use a compatibility map from another server, although you need to
|
|
adjust the
|
|
.I device_spec
|
|
field in the XkbDescRec accordingly. Note that symbol interpretations in a
|
|
compatibility map (
|
|
.I sym_interpret,
|
|
the vector of XkbSymInterpretRec structures) are also allocated using this same
|
|
function.
|
|
|
|
.I XkbSetCompatMap
|
|
copies compatibility map information from the keyboard description in
|
|
.I xkb
|
|
to the server specified in
|
|
.I display
|
|
's compatibility map for the device specified by the
|
|
.I device_spec
|
|
field of
|
|
.I xkb.
|
|
Unless you have specifically modified this field, it is the default keyboard
|
|
device.
|
|
.I which
|
|
specifies the compatibility map components to be set, and is an inclusive OR of
|
|
the bits shown in Table 1.

.TE
|
|
|
|
After updating its compatibility map for the specified device, if
|
|
.I update_actions
|
|
is True, the server applies the new compatibility map to its entire keyboard for
|
|
the device to generate a new set of key semantics, compatibility state, and a
|
|
new core keyboard map. If
|
|
.I update_actions
|
|
is False, the new compatibility map is not used to generate any modifications to
|
|
the current device semantics, state, or core keyboard map. One reason for not
|
|
applying the compatibility map immediately would be if one server was being
|
|
configured to match another on a piecemeal basis; the map should not be applied
|
|
until everything is updated. To force an update at a later time, use
|
|
.I XkbSetCompatMap
|
|
specifying
|
|
.I which
|
|
as zero and
|
|
.I update_actions
|
|
as True.
|
|
|
|
.I XkbSetCompatMap
|
|
returns True if successful and False if unsuccessful. The server may report
|
|
problems it encounters when processing the request subsequently via protocol
|
|
errors.
|
|
.SH "RETURN VALUES"
|
|
.TP 15
|
|
True
|
|
The
|
|
.I XkbSetCompatMap
|
|
function returns True if successful.
|
|
.TP 15
|
|
False
|
|
The
|
|
.I XkbSetCompatMap
|
|
function returns False if unsuccessful.

.SH STRUCTURES
|
|
.LP
|
|
The complete description of an Xkb keyboard is given by an XkbDescRec. The
|
|
component
|
|
structures in the XkbDescRec represent the major Xkb components.
|
|
|
|
.nf
|
|
typedef struct {
|
|
struct _XDisplay * display; /\(** connection to X server */
|
|
unsigned short flags; /\(** private to Xkb, do not modify */
|
|
unsigned short device_spec; /\(** device of interest */
|
|
KeyCode min_key_code; /\(** minimum keycode for device */
|
|
KeyCode max_key_code; /\(** maximum keycode for device */
|
|
XkbControlsPtr ctrls; /\(** controls */
|
|
XkbServerMapPtr server; /\(** server keymap */
|
|
XkbClientMapPtr map; /\(** client keymap */
|

XkbIndicatorPtr indicators; /\(** indicator map */
|

|
|
The
|
|
.I display
|
|
field points to an X display structure. The
|
|
.I flags field is private to the library: modifying
|
|
.I flags
|
|
may yield unpredictable results. The
|
|
.I device_spec
|
|
field specifies the device identifier of the keyboard input device, or
|
|
XkbUseCoreKeyboard, which specifies the core keyboard device. The
|
|
.I min_key_code
|
|
and
|
|
.I max_key_code
|
|
fields specify the least and greatest keycode that can be returned by the
|
|
keyboard.
|
|
|
|
Each structure component has a corresponding mask bit that is used in function
|
|
calls to
|
|
indicate that the structure should be manipulated in some manner, such as
|
|
allocating it
|
|
or freeing it. These masks and their relationships to the fields in the
|
|
XkbDescRec are
|
|
shown in Table 2.
