title: ttk Entry background colour
body: <p>How exactly do I change the background colour of an Entry widget from ttk? What I have so far is:</p>
  
  <pre><code>        self.estyle = ttk.Style()
          self.estyle.configure("EntryStyle.TEntry", background='black')
          self.estyle.map("EntryStyle.TEntry",
                          foreground=[('disabled', 'yellow'),
                                      ('active', 'blue')],
                          background=[('disabled', 'magenta'),
                                      ('active', 'green')],
                          highlightcolor=[('focus', 'green'),
                                          ('!focus', 'red')])
          self.urlentry_v = StringVar()
          self.urlentry = ttk.Entry(self.input_frame, style="EntryStyle.TEntry",
                                    textvariable=self.urlentry_v)
  </code></pre>
  
  <p>Basically, I've changed everything I can think of, but the text entry remains stubbornly white.</p>
  
  <p>Additionally, is there a way of changing the border colour?</p>
