DESCRIPTION

18       XkbOutOfRangeGroupNumber  returns the out-of-range group number, repre‐
19       sented as a group index, from the group_info field of  an  XkbSymMapRec
20       structure.
21
22       The  group_info field of an XkbSymMapRec is an encoded value containing
23       the number of groups of symbols bound to the key as well as the  speci‐
24       fication of the treatment of out-of-range groups. It is legal for a key
25       to have zero groups, in which case it also has  zero  symbols  and  all
26       events from that key yield NoSymbol.  To obtain the number of groups of
27       symbols bound to the key, use XkbKeyNumGroups.  To change the number of
28       groups  bound to a key, use XkbChangeTypesOfKey.  To obtain a mask that
29       determines the treatment of out-of-range  groups,  use  XkbKeyGroupInfo
30       and XkbOutOfRangeGroupInfo.
31
32       The  keyboard  controls contain a groups_wrap field specifying the han‐
33       dling of illegal groups on a global basis. That is, when the user  per‐
34       forms  an  action  causing  the  effective group to go out of the legal
35       range, the groups_wrap field specifies how to normalize  the  effective
36       keyboard  group  to  a group that is legal for the keyboard as a whole,
37       but there is no guarantee that the normalized group will be within  the
38       range  of  legal  groups for any individual key. The per-key group_info
39       field specifies how a key treats a legal effective  group  if  the  key
40       does  not  have a type specified for the group of concern. For example,
41       the Enter key usually has just one group defined. If the user  performs
42       an  action  causing  the global keyboard group to change to Group2, the
43       group_info field for the Enter key describes how to handle this  situa‐
44       tion.
45
46       Out-of-range  groups  for  individual  keys are mapped to a legal group
47       using the same options as are used for the overall keyboard group.  The
48       particular  type  of  mapping used is controlled by the bits set in the
49       group_info flag, as shown in Table 1.
