Class AccessibleTextAdapter
- All Implemented Interfaces:
- AccessibleTextListener
- Direct Known Subclasses:
- AccessibleTextExtendedAdapter
AccessibleTextListener interface.
 
 Classes that wish to deal with AccessibleTextEvents can
 extend this class and override only the methods that they are
 interested in.
 
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.
Note: This adapter is typically used by implementors of a custom control to provide very detailed information about the control instance to accessibility clients.
