This is what the documentation says about the parameters of 
gtk_tree_view_get_cursor 
(https://developer.gnome.org/gtk3/stable/GtkTreeView.html#gtk-tree-view-get-cursor):
/|
tree_view|/ : A GtkTreeView
/|path|/ : A pointer to be filled with the current cursor path, 
orNULL.*[**out**]*[transfer full][allow-none]
/|focus_column|/: A pointer to be filled with the current focus column, 
orNULL.*[**out**]*[transfer full][allow-none]

Noticed the [out] in path and focus column? That means you have to pass 
the pointers to a (GtkTreeViewColumn *) variable and a (GtkTreePath *) 
variable, instead of passing a (GtkTreeViewColumn **) variable and a 
(GtkTreePath **) variable.

You may do something like this then:

GtkTreeViewColumn *focus_column;
GtkTreePath *tree_path;

gtk_tree_view_get_cursor ( detect_object ( "DataDisplay", build_object 
), &tree_path, &focus_column );

Now focus_column and tree_path contains the currently focused column and 
path to its row, respectively.
