title: How to show placeholder in TEdit
body: <p>Is there any way to add a <a href="http://www.computerhope.com/jargon/p/plactext.htm" rel="nofollow noreferrer">placeholder</a> text to an <code>edit</code>?</p>
  
  <p>My only idea is to always manually set the color and the text of the given <code>edit</code> in its <code>OnChange</code> event, but it seems to be a bit tedious to me. </p>
  
  <p>Any other suggestions? </p>
