A GtkTreeRowReference C++ wrapper class.
<p>
A <a class="el" href="classGFC_1_1Gtk_1_1TreeRowReference.html">TreeRowReference</a> can be used to point to a node in a model, so long as it exists. The row reference will monitor all signals emitted by the model and update the node path appropriately.

<br>
You do not need to use this constructor. The row reference will keep pointing to the node pointed to by path, so long as it exists. However, unlike references created with the other constructors, it does not listen to the model for changes. The creator of the row reference must do this explicitly using <a class="el" href="classGFC_1_1Gtk_1_1TreeRowReference.html#e0">inserted()</a>, <a class="el" href="classGFC_1_1Gtk_1_1TreeRowReference.html#e1">deleted()</a> and <a class="el" href="classGFC_1_1Gtk_1_1TreeRowReference.html#e2">reordered()</a>. This must be called once per signal per proxy. This type of row reference is primarily meant for use when you need to carefully monitor exactly when a row reference updates itself. It is not generally needed by most applications. </td>
