XKB FUNCTIONS XkbKeyGroupInfo(3x11)

NAME

XkbKeyGroupInfo - Returns the number of groups of symbols

bound to the key corresponding to keycode

SYNOPSIS

cc [ flag... ] file... -lX11 [ library... ]

unsigned char XkbKeyGroupInfo (XkbDescPtr xkb, KeyCode key-

code); ARGUMENTS

- xkb

Xkb description of interest

- keycode

keycode of interest

DESCRIPTION

The group_info field of an XkbSymMapRec is an encoded value

containing the number of groups of symbols bound to the key

as well as the specification of the treatment of out-of-

range groups. It is legal for a key to have zero groups, in which case it also has zero symbols and all events from that

key yield NoSymbol. To obtain the number of groups of sym-

bols bound to the key, use XkbKeyNumGroups. To change the number of groups bound to a key, use XkbChangeTypesOfKey. To

obtain a mask that determines the treatment of out-of-range

groups, use XkbKeyGroupInfo and XkbOutOfRangeGroupInfo.

The keyboard controls contain a groups_wrap field specifying

the handling of illegal groups on a global basis. That is, when the user performs an action causing the effective group

to go out of the legal range, the groups_wrap field speci-

fies how to normalize the effective keyboard group to a group that is legal for the keyboard as a whole, but there is no guarantee that the normalized group will be within the

range of legal groups for any individual key. The per-key

group_info field specifies how a key treats a legal effec-

tive group if the key does not have a type specified for the group of concern. For example, the Enter key usually has

just one group defined. If the user performs an action caus-

ing the global keyboard group to change to Group2, the

group_info field for the Enter key describes how to handle

this situation.

Out-of-range groups for individual keys are mapped to a

legal group using the same options as are used for the overall keyboard group. The particular type of mapping used

is controlled by the bits set in the group_info flag, as

shown in Table 1. X Version 11 Last change: libX11 1.3.5 1
