I have no clue about the Python bindings, but in C you have to implement at least the "other side" (that is, the source) as a callback for the event "drag_data_get", which then makes the content available (dispatching on the content type, that's how source and destination negotiate what type to use). You register those same content types in the call to gtk_tree_view_enable_model_drag_source(). Note that whithin the same app you can pass (pointers to) internal data structures, whereas for cross-app drag-and-drop you have to convert the thing somehow. But maybe the Python bindings handle the marshalling for you.
