This reference will keep pointing to the node pointed to
by @path, so long as it exists. If @path isn’t a valid
path in @model, then %NULL is returned. However, unlike
references created with gtk_tree_row_reference_new(), it
does not listen to the model for changes. The creator of
the row reference must do this explicitly using
gtk_tree_row_reference_inserted(), gtk_tree_row_reference_deleted(),
gtk_tree_row_reference_reordered().
These functions must be called exactly once per proxy when the
corresponding signal on the model is emitted. This single call
updates all row references for that proxy. Since built-in GTK+
objects like #GtkTreeView already use this mechanism internally,
using them as the proxy object will produce unpredictable results.
Further more, passing the same object as @model and @proxy
doesn’t work for reasons of internal implementation.
This type of row reference is primarily meant by structures that
need to carefully monitor exactly when a row reference updates
itself, and is not generally needed by most applications.
You do not need to use this function.
