The QSensorManager class handles registration and creation of sensor backends.
Sensor plugins register backends using the registerBackend() function.
When QSensor::connectToBackend() is called, the createBackend() function will be called.
Create a backend for sensor. Returns null if no suitable backend exists.
This function was introduced in Qt Mobility 1.0.
Returns true if the backend identified by type and identifier is registered.
This is a convenience method that helps out plugins doing dynamic registration.
This function was introduced in Qt Mobility 1.2.
Register a sensor for type. The identifier must be unique.
The factory will be asked to create instances of the backend.
This function was introduced in Qt Mobility 1.0.
Unregister the backend for type with identifier.
Note that this only prevents new instance of the backend from being created. It does not invalidate the existing instances of the backend. The backend code should handle the disappearance of the underlying hardware itself.
This function was introduced in Qt Mobility 1.2.
Registers a static plugin, pluginname.
Note that this macro relies on static initialization so it may not be appropriate for use in a library and may not work on all platforms.
