Detailed Description

UNO Accessibility API.

This modules contains the basic interfaces of the UAA (UNO Accessibility API). Services that describe how these interfaces are implemented can be found in other modules. The services in this module describe only what every accessible object has to support.

Making a class accessible starts by supporting the com::sun::star::accessibility::XAccessible interface. This interface's only method returns the actual accessibility object, an instance of com::sun::star::accessibility::XAccessibleContext. These two interfaces may be implemented by the same class in which case a call to com::sun::star::accessibility::XAccessible getAccessible() returns the same object that is called. Alternatively the implementation of the com::sun::star::accessibility::XAccessibleContext interface can be done by another class. This makes it possible to put all accessibility implementations into their own library which has only to be loaded when necessary.

Note that all other interfaces have to be implemented by the same class that implements the com::sun::star::accessibility::XAccessibleContext interface. Note also that there is no way back from an accessibility object to the object from which it has been obtained by means of the UAA. If you need such a back-link you have to provide one on your own.
