title: Stop a tkinter subwindow (from Topleve()) being resized
body: <p>I know how to stop my main tkinter window being resized with:
  <code>self.mainWin.resizable(False,False)</code></p>
  <p>However, when I make a subwindow class, I do this:</p>
  <pre><code>self.subWin = tk.Toplevel(parent.mainWin)
  self.subWin.resizable(False,False)
  </code></pre>
  <p>which does not give any errors, but I can still resize the subwindow. Is there a trick to stopping resize of a subwindow created from <em>Toplevel()</em>?</p>
