__________________________________________________________________________________________________________________________________________________

NAME

       tk_optionMenu - Create an option menubutton and its menu

SYNOPSIS

       tk_optionMenu w varName value ?value value ...?
_________________________________________________________________

DESCRIPTION

       This  procedure	creates  an option menubutton whose name is w, plus an associated menu.  Together they allow the user to select one of the
       values given by the value arguments.  The current value will be stored in the global variable whose name is given by varName  and  it  will
       also be displayed as the label in the option menubutton.  The user can click on the menubutton to display a menu containing all of the val-
       ues and thereby select a new value.  Once a new value is selected, it will be stored in the variable and appear in the  option  menubutton.
       The current value can also be changed by setting the variable.

       The  return  value from tk_optionMenu is the name of the menu associated with w, so that the caller can change its configuration options or
       manipulate it in other ways.

KEYWORDS

       option menu
