+What's the #GtkTreeView equivalent of gtk_clist_find_row_from_data()?

+
+<answer>
+<para>
+As there is no separate data column in the #GtkTreeModel, there's no
+built in function to find the iter from data.  You can write a custom
+searching function to walk the tree and find the data, or use
+gtk_tree_model_foreach().
