at 1) How is one supposed to know this stuff with the "STRING" and "text/plain"?
It's nowhere documented, it only appears in the examples without further explanation,
so it looked completely random to me.
What other "types" are there for drag and drop targets?


the "text/plain" entry is a conventional MIME type. google for MIME.
the "STRING" entry is a hangover from historic X D-n-D, which was
developed before MIME (or at around the same time). google for "X atom string drag drop".


STRING is important for back-compatibility with many older
programs. Newer DnD handling is all MIME based, just like your email.

Ah okay. So I have to investigate the X dnd mechanism as well as GNOME MIME types to get a clue of the available draggable data types?
