For example, 
-----------------------------------------------------------------
require 'tk'
root = TkRoot.new.title("MenuOptionbutton")

list = ["1", "2", "3", "4", "5"]
var = TkVariable.new
button = TkOptionMenubutton.new(root,var,*list).pack
menu = button.menu
menu.bind('ButtonRelease-1', '@%y'){|y|
  value = menu.entrycget(y, :value)
  print var, ' -> ', value, "\n"
}
# OR, 
#menu.bind('ButtonRelease-1', '%y'){|y|
# value = menu.entrycget("@#{y}", :value)
# print var, ' -> ', value, "\n"
#}

Tk.mainloop
