Qt Sensors Backend#

Describes how to use the Qt Sensors backend.

The Qt Sensors backend connects the Qt Sensors API to the platform services or hardware sensors.

Overview#

QSensor instances talk to a backend object. Backends are usually supplied with the Qt Sensors library for a specific device, although third-party backends may be used as well. A backend can talk directly to hardware, or it can talk to a system service. In some instances it can even talk to another sensor. An example of this is the orientation sensor backend that talks to an accelerometer to determine the device orientation.

Backend Classes#

If you are making sensors available through the Sensors API, these are the classes to use.

PySide6.QtSensors.QSensorBackend

The QSensorBackend class is a sensor implementation.

PySide6.QtSensors.QSensorManager

The QSensorManager class handles registration and creation of sensor backends.

PySide6.QtSensors.QSensorBackendFactory

The QSensorBackendFactory class instantiates instances of QSensorBackend.

PySide6.QtSensors.QSensorPluginInterface

The QSensorPluginInterface class is the pure virtual interface to sensor plugins.

PySide6.QtSensors.QSensorChangesInterface

The QSensorChangesInterface class is the pure virtual interface to sensor plugins.
