well, i guess it depends on what data type you ask for. last time i
looked, the treeview could only provide information that made sense
inside the context of the treeview (e.g. row/col stuff) or text.
that's not my idea of "working".

we have DnD from treeviews to other widgets working on OS X without
issues in ardour (http://ardour.org), and we drag actual data from
them, not just text.
