 136 <p>
 137 The Navigation interface is used for creating and injecting navigation related
 138 events such as mouse button presses, cursor motion and key presses. The associated
 139 library also provides methods for parsing received events, and for sending and
 140 receiving navigation related bus events. One main usecase is DVD menu navigation.
 141 </p>
 142 <p>
 143 The main parts of the API are:

 151 GstNavigation event handling API. GstNavigation events are created in response to

 153 elements can use the navigation event API functions to parse the contents of received
 154 messages.

 160 mouse moving over a clickable region, or the set of available angles changing.
 161 </p>
 162 <p>
 163 The GstNavigation message functions provide functions for creating and parsing
