XkbKeyGroupsWidth(3)						   XKB FUNCTIONS					      XkbKeyGroupsWidth(3)

NAME
       XkbKeyGroupsWidth - Computes the maximum width associated with the key corresponding to keycode

SYNOPSIS
       int XkbKeyGroupsWidth (XkbDescPtr xkb, KeyCode keycode);

ARGUMENTS
       - xkb  Xkb description of interest

       - keycode
	      keycode 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.

       XkbKeyGroupsWidth computes the maximum width associated with the key corresponding to keycode.
