Description
|
|
Packit |
971217 |
The Navigation interface is used for creating and injecting navigation related
|
|
Packit |
971217 |
events such as mouse button presses, cursor motion and key presses. The associated
|
|
Packit |
971217 |
library also provides methods for parsing received events, and for sending and
|
|
Packit |
971217 |
receiving navigation related bus events. One main usecase is DVD menu navigation.
|
|
Packit |
971217 |
The main parts of the API are:
|
|
Packit |
971217 |
|
|
Packit |
971217 |
The GstNavigation interface, implemented by elements which provide an application
|
|
Packit |
971217 |
with the ability to create and inject navigation events into the pipeline.
|
|
Packit |
971217 |
GstNavigation event handling API. GstNavigation events are created in response to
|
|
Packit |
971217 |
calls on a GstNavigation interface implementation, and sent in the pipeline. Upstream
|
|
Packit |
971217 |
elements can use the navigation event API functions to parse the contents of received
|
|
Packit |
971217 |
messages.
|
|
Packit |
971217 |
GstNavigation message handling API. GstNavigation messages may be sent on the message
|
|
