java.lang.Object org.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 AccessibleTextEvent
s 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.
