tk_optionMenu - Create an option menubutton and its menu
tk_optionMenu w varName value ?value value
...?
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 values 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.
