title: Remove title bar in Python 3 Tkinter Toplevel
body: <p>I'm trying to create a static Toplevel window with some text and no title bar with Tkinter in Python 3.6.1 on OS X 10.12.5. I believe that <code>wm_overrideredirect(True)</code> is the method I need to achieve this, but whenever I enter this line, the Toplevel window is not displayed. When I remove this line, the Toplevel is displayed (with a title bar).</p>
  
  <p>What am I doing wrong!? This is the code I have.</p>
  
  <pre><code>import tkinter as tk
  
  root = tk.Tk()
  
  tw = tk.Toplevel()
  tw.wm_overrideredirect(True)              # Toplevel will not display due to this line
  tk.Label(tw, text='Some text').pack()
  
  root.mainloop()
  </code></pre>
