public interface AccessibleExtendedText

The AccessibleExtendedText interface contains additional methods not provided by the AccessibleText interface Applications can determine if an object supports the AccessibleExtendedText interface by first obtaining its AccessibleContext (see Accessible) and then calling the AccessibleContext.getAccessibleText() method of AccessibleContext. If the return value is an instance of AccessibleExtendedText, the object supports this interface.

Since:

Parameters:

part - the CHARACTER, WORD, SENTENCE, LINE or ATTRIBUTE_RUN to retrieve

index - an index within the text
