.SH DESCRIPTION
|
||
|
|
.LP
|
||
|
|
The key width and number of groups associated with a key are used to form a
|
||
|
|
small two-dimensional array of KeySyms for a key. This array may be different
|
||
|
|
sizes for different keys. The array for a single key is stored as a linear list,
|
||
|
|
in row-major order. The arrays for all of the keys are stored in the
|
||
|
|
.I syms
|
||
|
|
field of the client map. There is one row for each group associated with a key
|
||
|
|
and one column for each level. The index corresponding to a given group and
|
||
|
|
shift level is computed as:
|
||
|
|
.nf
|
||
|
|
|
||
|
|
idx = group_index * key_width + shift_level
|
||
|
|
|
||
|
|
.fi
|
||
|
|
The
|
||
|
|
.I offset
|
||
|
|
field of the
|
||
|
|
.I key_sym_map
|
||
|
|
entry for a key is used to access the beginning of the array.
|
||
|
|
|
||
|
|
.I XkbKeyNumSyms
|
||
|
|
returns the total number of keysyms for the key corresponding to
|
||
|
|
.I keycode.
