title: Scroll of a texbox always on bottom
body: <p>There is a way to keep the scroll on bottom for a multi line textbox?</p>
  
  <p>Something like in the vb6 </p>
  
  <pre><code>txtfoo.selstart=len(txtfoo.text)
  </code></pre>
  
  <p>I'm trying with txtfoo.selectionstart=txtfoo.text.length without success.</p>
  
  <p>Regards.</p>
