I have not looked at the DnD code much, but the targets are probably atoms
(integer indices into a table of strings stored on the X server). You can
convert the atom into a string with gdk_atom_name().
If you are poking around in the DnD internals, you have probably missed
something (unless you are doing something really complicated). Try
looking at GHex (in gnome-utils) as a simple example of drag and drop.
Another example showing different levels of complexity is the testdnd
example distributed with gtk+.
