title: Tkinter grid manager bad screen distance
body: <p>I tried using the Grid manager and wanted to place 4 buttons in 2 rows and 2 columns with this code:</p>
  <pre class="lang-py prettyprint-override"><code>button1 = Button(window, wrap=&quot;Button1&quot;, width=10)
  button1.grid(row=0, column=0)
  button1.pack()
  
  button2 = Button(window, wrap=&quot;Button2&quot;, width=10)
  button2.grid(row=0, column=1)
  button2.pack()
  
  button3 = Button(window, wrap=&quot;Button3&quot;, width=10)
  button3.grid(row=1, column=0)
  button3.pack()
  
  button4 = Button(window, wrap=&quot;Button4&quot;, width=10)
  button4.grid(row=1, column=1)
  button4.pack()
  </code></pre>
  <p>And I got this error:</p>
  <pre><code>_tkinter.TclError: bad screen distance &quot;Button1&quot;
  </code></pre>
  <p>I don't know what a screen distance is and don't know how to fix a bad one. Can someone please help me there, please?</p>
