The DND API has a couple of layers, on one layer you do everything
yourself and on the other layer you say something high-level like
"this widget is a drag source" and GTK does it for you.

So basically you want to call gtk_drag_begin() yourself in say a
button press event, instead of using gtk_drag_source_set(), IIRC.
The new text widget in the devel tree has an example (gtktextview.c).
