[Arkadi Shalaginov]

Command itemconfigure index column list ?list
Allows one to configure any given cell of a
mclistbox. The arguments index and column specify a
cell to be configures.
list argument is a set of option-value pairs as in the
listbox command itemconfigure.

::mclistbox::ResizeColumnsOfAllListboxes
This command adjusts widths of columns according to set
fonts of all mclistboxes in active an application. This
function is supposed to be called after any font
change.

Option -selectcolumn
Specifies behavior of selection. If -selectcolumn is
set to 1 and -selectmode is set to single,
then only one cell instead of hole line is highlighted
upon click. Default value is 0.

Opton -usexscroll
Specifies whether corresponding xscrollbar is visible.
This option works only if -usecolumnxscroll is set to
1. If the value is 1,
it makes corresponding xscrollbar visible. Default
value is 1.

PS. Sorry for previous anonymous submission of the same
patch.
