Ok, I see now. Unfortunatly that doesn't seem an option for me. I use
python bindings, and I can't create a sub-class of TreeModelFilter. The
only way to create a TreeModelfilter in PyGTK is to call a
model.filter_new().

Anyway thanks for your replies, I'll go with drag_drop signal, get
selection_data with gtk.Widget.drag_get_data, get the position with
gtk.TreeView.get_dest_row_at_pos, call context.finish() and stop the
propagation of the event.

does that sound a reasonable way to do that?
