### Method

# Gtk Accessibleupdate_relation

#### Declaration [src]

    void
    gtk_accessible_update_relation (
      GtkAccessible* self,
      GtkAccessibleRelation first_relation,
      ...
    )

#### Description [src]

Updates a list of accessible relations.

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

If the `GtkAccessibleRelation` 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

`first_relation` | `GtkAccessibleRelation`
| The first `GtkAccessibleRelation`
`...` | `none`
| A list of relation and value pairs, terminated by -1
