public interface AccessibleValueTheAccessibleValueinterface should be supported by any object that supports a numerical value (e.g., a scroll bar). This interface provides the standard mechanism for an assistive technology to determine and set the numerical value as well as get the minimum and maximum values. Applications can determine if an object supports theAccessibleValueinterface by first obtaining itsAccessibleContext(seeAccessible) and then calling theAccessibleContext.getAccessibleValue()method. If the return value is notnull, the object supports this interface.
