PySide6.QtSensors.QSensorManager

class QSensorManager

The QSensorManager class handles registration and creation of sensor backends.

Details

Sensor plugins register backends using the registerBackend() function.

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

static createBackend(sensor)
Parameters:

sensor – QSensor

Return type:

QSensorBackend

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

static isBackendRegistered(type, identifier)
Parameters:
Return type:

bool

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 registerBackend(type, identifier, factory)
Parameters:

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 setDefaultBackend(type, identifier)
Parameters:

Sets or overwrite the sensor type with the backend identifier.

static unregisterBackend(type, identifier)
Parameters:

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.
