Re: Enable drag and drop for treeview?

["Paul Davis" <pjdavis engineering uiowa edu>]

Jeff,

I think to do this, you have to subclass Gtk::TreeModel and override
Gtk::TreeDragDest::drag_data_received_vfunc()

I did something similar here:

http://trac.lsdcas.engineering.uiowa.edu/browser/trunk/cas2/plugins/viewer/event_analysis/treemodel.cc

There's also an example in the book about doing this stuff which is
what I based my implementation on:

http://www.gtkmm.org/docs/gtkmm-2.4/examples/book/treeview/drag_and_drop/
