I'm afraid you will probably get the response that it's not Delphi

Of course your approach is not yet Delphi compatible, but it *can* be

Please specify what non-trivial use you have in mind, and what
results you expect to see in this very early implementation stage
(proof of concetpt).

1. what GUI environments are there that do not have clipboards?
Dunno. Most will have such a feature, but the implementation can vary.
2. are there any that do /not/ use the clipboard for DnD

Your current implementation is restricted to purely textual information,
Simply because I was in a rush to implement the basic workings of DND
for a new project of ours. Textual information was good enough to get
that app's DND going. The DND does does lend itself to other data
types too.

Just to be clear, the current textual data restriction in fpGUI's DND

I not sure if I understand the original statement, but in fpGUI I use
the mime types to register the data that must be transfered via DND.
Under Windows, I also register common mime-types that have easy
mappings
