NAME

6       XkbSetNames - Change the symbolic names in the server
7

SYNOPSIS

9       Bool  XkbSetNames  (Display  *dpy,  unsigned  int  which,  unsigned int
10              first_type, unsigned int num_types, XkbDescPtr xkb);
11

ARGUMENTS

13       - dpy  connection to the X server
14
15       - which
16              mask of names or map components to be changed
17
18       - first_type
19              first type whose name is to be changed
20
21       - num_types
22              number of types for which names are to be changed
23
24       - xkb  keyboard description from which names are to be taken
25

DESCRIPTION

27       To change the symbolic names in the server, first modify a  local  copy
28       of  the  keyboard  description  and then use either XkbSetNames, or, to
29       save network traffic, use a  XkbNameChangesRecstructure  and  call  Xk‐
30       bChangeNames  to  download  the changes to the server.  XkbSetNames and
31       XkbChangeNames can generate BadAlloc, BadAtom, BadLength, BadMatch, and
32       BadImplementation errors.
33
34       Use XkbSetNames to change many names at the same time. For each bit set
35       in which, XkbSetNames takes the corresponding value (or values  in  the
36       case  of  arrays) from the keyboard description xkb and sends it to the
37       server.
38
39       The first_type and num_types arguments are  used  only  if  XkbKeyType‐
40       NamesMask  or  XkbKTLevelNamesMask is set in which and specify a subset
41       of the types for which the corresponding names are to  be  changed.  If
42       either  or  both of these mask bits are set but the specified types are
43       illegal, XkbSetNames returns False and does not update any of the names
44       specified  in  which.   The specified types are illegal if xkb does not
45       include a map component or if first_type and  num_types  specify  types
46       that are not defined in the keyboard description.

STRUCTURES

49       The  XkbNameChangesRec  allows applications to identify small modifica‐
50       tions to the symbolic names and effectively reduces the amount of traf‐
51       fic sent to the server:
52
53           typedef struct _XkbNameChanges {
54               unsigned int   changed;          /∗ name components that have changed */
55               unsigned char  first_type;       /∗ first key type with a new name */
56               unsigned char  num_types;        /∗ number of types with new names */
57               unsigned char  first_lvl;        /∗ first key type with new level names
58       */
59               unsigned char  num_lvls;         /∗ number of key types with new level
60       names */
61               unsigned char  num_aliases;      /∗ if key aliases changed, total number
62       of key aliases */
63               unsigned char  num_rg;           /∗ if radio groups changed, total
64       number of radio groups */
65               unsigned char  first_key;        /∗ first key with a new name */
66               unsigned char  num_keys;         /∗ number of keys with new names */
67               unsigned short changed_vmods;    /∗ mask of virtual modifiers for which
68       names have changed */
69               unsigned long  changed_indicators; /∗ mask of indicators for which names
70       were changed */
71               unsigned char  changed_groups;     /∗ mask of groups for which names
72       were changed */
73           } XkbNameChangesRec, *XkbNameChangesPtr
74
75       The  changed  field specifies the name components that have changed and
76       is the bitwise inclusive OR of the valid names mask bits defined in Ta‐
77       ble  1. The rest of the fields in the structure specify the ranges that
78       have changed for the various kinds of symbolic names, as shown in Table
79       2.
80
81       Xkb  provides  several functions that work with symbolic names. Each of
82       these functions uses a mask to specify individual fields of the  struc‐
83       tures  described  above.  These  masks  and  their relationships to the
84       fields in a keyboard description are shown in Table 1.
