title: Tkinter Aspect Ratio
body: <p>How can I keep the aspect ratio of a Tkinter window fixed?  I want my window to
  stay square, no matter what its size is. The aspect method seemed
  promising, but when I tried the following code, nothing happened.</p>
  
  <pre><code>win = Toplevel(master)
  win.grid()
  win.aspect(1,1,1,1)
  </code></pre>
  
  <p>The aspect could still be changed whenever I resized the window. Any ideas?</p>
