# Gtk::TreeRowReference Class Reference
[TreeView Classes]

List of all members.

## Detailed Description

Typedefed as Gtk::TreeModel::RowReference.

This reference will keep pointing to the node pointed to by the Path, so long as it exists. It listens to all signals emitted by the Model, and updates its Path appropriately.
