title: How do I put a semi transparent layer on my form
body: <p>I have read some questions about this in the last week or so, on stackoverflow.</p>
  
  <p>My requirement is more or less the same.</p>
  
  <p>I need to put a semi-transparent layer on top my form, but this form may have several other components: Lists, Edits, Labels, Images ,etc</p>
  
  <p>I need this semi-transparent layer to be on top of all that.</p>
  
  <p>The idea is to fade areas of the form that the use those not, or cannot access in that moment.</p>
  
  <p>I use Delphi 2007.</p>
  
  <p>Thanks</p>
