title: tkinter option menu wont set title
body: <p>I cant get my option menu to display a title, I've done this in other programs and it worked fine. I even copied working code to this project and here it doesnt work. Is there something I'm missing?</p>
  
  <p>The window is executed by calling it by the press of a button</p>
  
  <pre><code>def agregarEquipo(event=None):
      window = tk.Tk()
      wTitle = 'Example title'
      window.title(wTitle)
      window.configure(bg=bgColor_1)
      window.geometry('%dx%d' % (windX, windY))
  
      # The option menu
      listaEquipos = ['Equipos'] 
      menuEquipoText = tk.StringVar()
      menuEquipoText.set(listaEquipos[0])
      menuEquipo = tk.OptionMenu(window,menuEquipoText,*'Hello')
      menuEquipo.grid(row=0, column=0)
  
      window.mainloop()
  </code></pre>
  
  <p>Thanks in advance!</p>
