title: How to get Scrollbar notifications from a TMemo control?
body: <p>I have a VCL <code>TMemo</code> control and need to be notified every time the text is scrolled. There is no <em><code>OnScroll</code></em> event and the scroll messages doesn't seem to propagate up to the parent form.</p>
  
  <p>Any idea of how to get the notification?
  As a last resort I can place an external <code>TScrollBar</code> and update the <code>TMemo</code> in the <em><code>OnScroll</code></em> event, but then I have to keep them in sync when I move the cursor or scroll the mouse wheel in <code>TMemo</code>...</p>
