Re: DnD targets question

[James Henstridge <james daa com au>]

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+.

James.
