Please forgive me for "thinking in Python" in my reply.

If you want the column where the mouse pointer is, you can use
TreeView.get_pointer() to get the pointer pos relative to the TreeView and
then use TreeView.get_path_at_pos().  This will net you a Path, a
TreeViewColumn, and cell_x and cell_y, the position relative to the cell.
Now here's where I'm not quite sure I understand the intentions of the
designers since TreeModel.get_value() requires a numeric column.  I see 2
ways to get the column number: do a linear search through the columns gotten
with TreeView.get_columns() for a match to the TreeViewColumn retrieved above,
or retrieve a column number attached at creation time with
TreeViewColumn.set_data().  The former is the one to use if your going to be
changing the column order I suppose.  I currently use the latter method.
Maybe I'm missing something, though.  

Oh, the other case is if you want the column where the text cursor is.  You
can use TreeView.get_cursor() for this.  Again, this returns a Path and a
TreeViewColumn.
