XkbKeyGroupWidth(3)
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.
