public interface AccessibleTextListener
extends org.eclipse.swt.internal.SWTEventListener
After creating an instance of a class that implements
this interface it can be added to a control using the
addAccessibleTextListener method and removed
using the removeAccessibleTextListener method.
When a client requests information the appropriate method
will be invoked.
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.
Note: This interface is typically used by implementors of a custom control to provide very detailed information about the control instance to accessibility clients.
