Sent when an accessibility client requests the current character offset of the text caret. The default behavior is to do nothing. <p> Return the caret offset in the <code>offset</code> field of the event object. </p>
Sent when an accessibility client requests the range of the current text selection. The default behavior is to do nothing. <p> Return the selection start offset and non-negative length in the <code>offset</code> and <code>length</code> fields of the event object. </p>

This adapter class provides default implementations for the methods described by the <code>AccessibleTextListener</code> interface. <p> Classes that wish to deal with <code>AccessibleTextEvent</code>s can extend this class and override only the methods that they are interested in. </p><p> Note: Accessibility clients use child identifiers to specify whether they want information about a control or one of its children. Child identifiers are increasing integers beginning with 0. The identifier CHILDID_SELF represents the control itself. When returning a child identifier to a client, you may use CHILDID_NONE to indicate that no child or control has the required information. </p><p> Note: This adapter is typically used by implementors of a custom control to provide very detailed information about the control instance to accessibility clients. </p>
