Although the identification and testing of GEF components is supported out-of-the-box, it is highly recommended that application developers enhance this support by implementing an accessibility plug-in for their application.

Apart from the general description for creating toolkit extensions in this manual, we give further information for extending the GEF toolkit. The following sections explain how to develop a GEF accessibility plug-in.
