GNOME
[1]
applications use the GTK+ interfaces for drag and
drop, however GNOME also adds some more conventions
about the types of data that are drag-and-dropped,
and perhaps more importantly, provides an environment
to the user in which drag-and-drop is available
thoughout. The most prominent place source and target
for drag-and-drop in GNOME is gmc,
the GNOME file manager. gmc not
only allows the user to access the file system, it also
manages the desktop. The desktop provides a central
place for the user to drop files, URL's, program
launchers, and other types of data.
The drag-and-drop implementation in GTK+ is quite complete
and should provide for the needs of GNOME for the
forseeable future. However, what will develop is the
type of objects that are tranferred via drag-and-drop.
Currently, most drag-and-drop in GNOME is transferring
file names; as the Bonobo document model becomes used
in more parts of GNOME, it will become more common
to transfer the object references for Bonobo objects via
drag-and-drop. This will result in considerable more power and
flexibility since it will be possible to do things like
change the form of transferred data after
it has been transferred, and also to do true hot-link
embedding of one document into another.
