Detailed Description#

Sensor plugins register backends using the registerBackend() function.

When connectToBackend() is called, the createBackend() function will be called.

class PySide6.QtSensors.QSensorManager#
static PySide6.QtSensors.QSensorManager.createBackend(sensor)#


Return type:


Create a backend for sensor. Returns null if no suitable backend exists.

static PySide6.QtSensors.QSensorManager.isBackendRegistered(type, identifier)#
Return type:


Returns true if the backend identified by type and identifier is registered.

This is a convenience method that helps out plugins doing dynamic registration.

static PySide6.QtSensors.QSensorManager.registerBackend(type, identifier, factory)#

Register a sensor for type. The identifier must be unique.

The factory will be asked to create instances of the backend.

Sensor identifiers starting with generic or dummy are given lower priority when choosing the default sensor if other sensors are found.

static PySide6.QtSensors.QSensorManager.setDefaultBackend(type, identifier)#

Sets or overwrite the sensor type with the backend identifier.

static PySide6.QtSensors.QSensorManager.unregisterBackend(type, identifier)#

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.
