title: Cannot use geometry manager pack inside
body: <p>So I'm making an rss reader using the tkinter library, and in one of my methods I create a text widget. It displays fine until I try to add scrollbars to it.</p>
  
  <p>Here is my code before the scrollbars: </p>
  
  <pre><code>   def create_text(self, root):
          self.textbox = Text(root, height = 10, width = 79, wrap = 'word')
          self.textbox.grid(column = 0, row = 0)
  </code></pre>
  
  <p>Here is my code after:</p>
  
  <pre><code>def create_text(self, root):
          self.textbox = Text(root, height = 10, width = 79, wrap = 'word')
          vertscroll = ttk.Scrollbar(root)
          vertscroll.config(command=self.textbox.yview)
          vertscroll.pack(side="right", fill="y", expand=False)
          self.textbox.config(yscrllcommand=vertscroll.set)
          self.textbox.pack(side="left", fill="both", expand=True)
          self.textbox.grid(column = 0, row = 0)
  </code></pre>
  
  <p>This gives me the error </p>
  
  <blockquote>
    <p>_tkinter.TclError: cannot use geometry manager pack inside .56155888 which already has slaves managed by grid on the line
    vertscroll.pack(side="right", fill="y", expand=False)</p>
  </blockquote>
  
  <p>Any ideas how to fix this?</p>
