That kind of drag-and-drop, dragging files from Windows Explorer and
dropping on a GTK+ application, *does* work fine on Windows. It's
generic inter-application drag-and-drop that is not implemented. It
should work fine to just use the same code as for X11 in the
application. (Support for file dnd from Explorer is handled with a
different, much older and simpler, API than what generic drag-and-drop
would require.)

Well, gtk_selection_data is just an API detail in GTK+; it has little
to do with the actual windowing system (X11 or Windows) concepts. The
window manager on X11, or the X server, has no knowledge of
gtk_anything either.

Do you actually have a problem? Have you tested dragging-and-dropping
files from Explorer?
