NAME

       XkbKeyGroupWidth  -  Computes the width of the type associated with the
       group grp for the key corresponding to keycode

SYNOPSIS

       int XkbKeyGroupWidth (XkbDescPtr xkb, KeyCode keycode, int grp);

ARGUMENTS

       - xkb  Xkb description of interest

       - keycode
              keycode of interest

       - grp  group of interest

DESCRIPTION

       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 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:

            idx = group_index * key_width + shift_level

       The offset field of the key_sym_map entry for a key is used  to  access
       the beginning of the array.

       XkbKeyGroupWidth  computes  the  width  of the type associated with the
       group grp for the key corresponding to keycode.
