22 * Classes that wish to deal with <code>AccessibleTextEvent</code>s can

26 * Note: Accessibility clients use child identifiers to specify
27 * whether they want information about a control or one of its children.
28 * Child identifiers are increasing integers beginning with 0.
29 * The identifier CHILDID_SELF represents the control itself.
30 * When returning a child identifier to a client, you may use CHILDID_NONE
31 * to indicate that no child or control has the required information.
32 * </p><p>
33 * Note: This adapter is typically used by implementors of
34 * a custom control to provide very detailed information about
35 * the control instance to accessibility clients.
