+Interface methods behave very similarly to virtual/override methods.
+As with override methods, you can use PARENT_HANDLER in the definition of an
+interface method to call the implementation of the same interface method in
+a parent class.
+.PP
+The NAME_parent_iface variable may be used to access the complete interface
+structure from a parent class, where NAME is the implemented interface (with
+colons replaced by underscores).
+This enables access to the full parent implementation of an interface.
+For example, if a class implements the Gtk:Tree:Model interface then the
+implementation of the same interface in the parent class is available via
+the Gtk_Tree_Model_parent_iface pointer.
+If an interface is not implemented in the parent class, then the corresponding
+parent_iface value will be a null pointer.

 The following example implements a new object, that implements the
 Gtk:Tree:Model interface and implements the get_flags method of that
 interface.  Do note that except for standard (GTK+ and glib) specific
