title: How can I add scrollbars to a SkinnableContainer created runtime?
body: <p>I created a SkinnableContainer runtime because I want to set some style properties to it, then based on some external data I need to create a new SkinnableContainer and add it as children of the first one. This children height can be greater than the parent container.</p>
  
  <p>How can I create a SkinnableContainer runtime with some scrollbars?<br>

  <p>It is possible runtime to achieve the same result ?</p>
  
  <pre><code>// ... in a container ...
  
  var father = new SkinnableContainer();
  this.addElement(father);
  
  var child = new SkinnableContainer();
  // ... some initialization... child is filled with some other elements from outside
  
  father.addElement(child);
  
  // ... now if child.height &gt; father.height 
  // I want to add a vertical scrollbar
  </code></pre>
