It may be a protected method, invisible outside the Controls unit?

The Lazarus implementation of Drag&Drop is somewhat Delphi incompatible 
and overly flawed. I already suggested some improvements, but no Lazarus 
developer did yet dare to touch that part of the LCL. Instead 
AnchorDocking was introduced as a replacement for Delphi D&D, and nobody 
(but me) ever tried to understand how Delphi compatible D&D could be 
made work properly. All I could achieve was the EasyDockManager and 
EasyDockMaster, which work around most flaws in the basic 
implementation. This was the state when I stopped any fruitless attempts 
to contribute to the LCL.
