Interface AccessibleIcon

All Known Implementing Classes:: ImageIcon.AccessibleImageIcon

public interface AccessibleIcon

The AccessibleIcon interface should be supported by any object that has an associated icon (e.g., buttons). This interface provides the standard mechanism for an assistive technology to get descriptive information about icons. Applications can determine if an object supports the AccessibleIcon interface by first obtaining its AccessibleContext (see Accessible) and then calling the AccessibleContext.getAccessibleIcon() method. If the return value is not null, the object supports this interface.
