title: Make a Toplevel window take up the entire monitor space?
body: <p>I'm trying to make a tkinter Toplevel window to go full screen and take up the entire monitor space (going over the task bar as well). I am able to do this with the <code>Tk()</code> using the code: <code>window.attributes("-fullscreen", True)</code>. But I know you can't have two instances of <code>Tk()</code> so I need to use a Toplevel and <code>root.attributes("-fullscreen", True)</code> does not work with Toplevel. </p>
  
  <p>The code I have in place at the moment to make the Toplevel fullscreen is this:</p>
  
  <pre><code>window = Toplevel()
   w = window.winfo_screenwidth()
   h = window.winfo_screenheight()
   window.geometry("%dx%d+0+0" % (w,h))
  </code></pre>
  
  <p>But this does not even go into a proper fullscreen mode as the left side of the interface does not reach the edge of the screen. </p>
  
  <p>How can I get a Toplevel window to take up the entire space of the screen like a Tk() window can?</p>
