Thank you for pointing that out. 

For what concerns dragging a row of a GTree.view: 
I've just made some trials and I see that the GTree.view itself can be 
dragged, and since the drag contents can be set with a selection callback, 
the result is that the content of a particular cell can be dragged, without 
using any extra column. Great!
