update_relation

Updates a list of accessible relations.

This function should be called by Widget types whenever an accessible relation change must be communicated to assistive technologies.

If the AccessibleRelation requires a list of references, you should pass each reference individually, followed by null, e.g.

  gtk_accessible_update_relation (accessible,
                                  GTK_ACCESSIBLE_RELATION_CONTROLS,
                                    ref1, NULL,
                                  GTK_ACCESSIBLE_LABELLED_BY,
                                    ref1, ref2, ref3, NULL,
                                  -1);

Parameters:

this	a Accessible
...	a list of relation and value pairs, terminated by -1
first_relation	the first AccessibleRelation
