DESCRIPTION

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