title: How ro change a Tkinter ScrolledText widget's Scrollbar color?
body: <p>I'm using the module <code>ScrolledText</code> in a Tkinter GUI.</p>
  <p>I wish to change the colour of the <code>Scrollbar</code> encompassed in the <code>ScrolledText</code> widget, but I'm having some difficulty.</p>
  <p>My syntax is correct (according to documentation).</p>
  <pre><code>Box = ScrolledText(root)
  Box.vbar.config(troughcolor = 'red', bg = 'blue')
  Box.pack()
  </code></pre>
  <p>However, the scrollbar still has the standard grey colour.</p>
  <p>I know the syntax is correct, because doing other things such as:</p>
  <pre><code> Box.vbar.config(cursor = 'target')   
  </code></pre>
  <p>...works exactly as it should.</p>
  <p>However, attempting to change the <code>relief</code>, <code>borderwidth</code> or colors don't seem to have any effect.<br />
  Why is this happening?</p>
