TreeRowReferenceProtocol

public protocol TreeRowReferenceProtocol

A GtkTreeRowReference tracks model changes so that it always refers to the same row (a GtkTreePath refers to a position, not a fixed row). Create a new GtkTreeRowReference with gtk_tree_row_reference_new().

The TreeRowReferenceProtocol protocol exposes the methods and properties of an underlying GtkTreeRowReference instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see TreeRowReference. Alternatively, use TreeRowReferenceRef as a lighweight, unowned reference if you already have an instance you just want to use.
