[Lazarus] Drag (and show) images

Hi All!

I am trying to write an app that allows me to drag images and show them 
while they are being dragged (like the cards in Solitaire).

I have been able to drag images (showing only the drag cursor) and drop 
them appropriately, but I haven't been able to find any recent 
documentation showing the use of TDragImageList and TDragObject.

The only articles that I have found are for Delphi from 2011 (which 
translates to Lazarus but doesn't work correctly) and some more recent 
that don't show the dragged image while the drag is taking place (I have 
that part working).

I was able to show a dragged image by adding code to the DragOver event, 
but that seems to take more time than it should.

Can anyone point me in the right direction for this?
