title: TTK theme not working, just old-fashioned tkinter
body: <p>On my computer with Win8.1 when I use following code</p>
  
  <pre><code>   from tkinter import *
     from tkinter.ttk import *
  
     Tk().mainloop()
  </code></pre>
  
  <p>I see only the old looking tkinter. Any idea how to fix it?</p>

  <p>I tried to use different theme with no result. </p>
  
  <p>For some reason following code:</p>
  
  <pre><code>from tkinter import *
  from tkinter.ttk import *
  
  Style().theme_use("alt")
  Tk().mainloop()
  </code></pre>
  
  <p>results with two identical tkinter old-fashioned windows which seems not to be correct.</p>
  
  <p>PS: It seems to be issue related with Win8.1, see here:

  <p>But I found no information how to fix it. Any news would be welcome. :)</p>
  
  <p>EDIT1:
  After trying following snippet:</p>
  
  <pre><code>from tkinter import *
  from tkinter.ttk import *
  from functools import partial
  
  root = Tk()
  style = Style(root)
  
  def change(name, style):
      style.theme_use(name)
  
  for s in style.theme_names():
      lb = Button(root, text=s, command=partial(change, s, style))
      lb.pack()
  </code></pre>
  
  <p>I could say the themes are changing not only for color but completely. What is still puzzling me is I cannot see the nice fancy graphic which I expect to see.
  I tried to change my windows settings for performance or to visual aspect but it is not the reason why it is not working.</p>
  
  <p>If you have Win 8.1 do you have tkk working as expected?</p>
  
  <p>EDIT2:
  This is my look using example from 
  <a href="http://www.tkdocs.com/tutorial/firstexample.html" rel="nofollow noreferrer">http://www.tkdocs.com/tutorial/firstexample.html</a>
  (Win7 and Win8.1)</p>
