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 TreeRowReference.new, it
does not listen to the model for changes. The creator of
the row reference must do this explicitly using
TreeRowReference.inserted, TreeRowReference.deleted,
TreeRowReference.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 gtk.TreeView 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.
