java.lang.Objectorg.eclipse.swt.accessibility.AccessibleTextAdapter
public abstract class AccessibleTextAdapter
This adapter class provides default implementations for the
methods described by the 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.
