title: Is it possible to Alpha Blend a VCL control on a TForm?
body: <p>Is it possible to Alpha Blend or implement a similar effect for a VCL control on a TForm? </p>
  
  <p>For example, consider the following screenshot where two TPanels are placed on a TForm in addition to other controls. Both the panels are made draggable (<em>See</em> <a href="http://delphi.about.com/library/weekly/aa102505a.htm" rel="nofollow noreferrer">How to Move and Resize Controls at Run Time</a>).</p>
  
  <p>Now, is it possible to make these panels translucent while dragging so that you can see what is underneath? <em>(as shown in the second image which was produced by image manipulation)</em></p>
