title: Programmatically scroll QScrollArea
body: <p>I have a Widget with QScrollArea in it and I want it to be scrolled down right after the widget containing it is shown. I tried:</p>
  
  <pre><code>scrollArea-&gt;ensureVisible(0,100, 20, 20);
  </code></pre>
  
  <p>It works only when invoked by user (pushing button for example). Putting it in widget contstructor or showEvent doesn't work. Can it be done automatically?</p>
