NAME
XkbKeyGroupInfo - Returns the number of groups of symbols bound to the key corresponding to keycode SYNOPSIS unsigned char XkbKeyGroupInfo (XkbDescPtr xkb, KeyCode keycode); ARGUMENTS
- xkb Xkb description of interest
- keycode keycode of interest DESCRIPTION The groupinfo field of an XkbSymMapRec is an encoded value containing the number of groups of symbols bound to the key as well as the speci‐
fication 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 symbols 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 groupswrap field specifying the han‐ dling of illegal groups on a global basis. That is, when the user per‐ forms an action causing the effective group to go out of the legal range, the groupswrap field specifies 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 groupinfo field specifies how a key treats a legal effective 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 causing the global keyboard group to change to Group2, the groupinfo field for the Enter key describes how to handle this situa‐ tion.
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 groupinfo flag, as shown in Table 1.
