Synopsis

Functions

• def setTimestamp (timestamp)

• def timestamp ()

• def value (index)

• def valueCount ()

Virtual functions

• def copyValuesFrom (other)

Detailed Description

Note that QSensorReading is not particularly useful by itself. The interesting data for each sensor is defined in a sub-class of QSensorReading .

PySide2.QtSensors.QSensorReading.copyValuesFrom(other)

Parameters

other – QSensorReading

Copy values from other into this reading. Implemented by sub-classes using the DECLARE_READING() and IMPLEMENT_READING() macros.

Note that this method should only be called by QSensorBackend .

PySide2.QtSensors.QSensorReading.setTimestamp(timestamp)

Parameters

timestamp – quint64

Sets the timestamp of the reading.

timestamp()

PySide2.QtSensors.QSensorReading.timestamp()

Return type

quint64

Returns the timestamp of the reading.

setTimestamp()

PySide2.QtSensors.QSensorReading.value(index)

Parameters

index – int

Return type

object

Returns the value of the property at index .

Note that this function is slower than calling the data function directly.

Here is an example of getting a property via the different mechanisms available.

Accessing directly provides the best performance but requires compile-time knowledge of the data you are accessing.

QAccelerometerReading *reading = ...;
qreal x = reading->x();

You can also access a property by name. To do this you must call property() .

qreal x = reading->property("x").value<qreal>();

Finally, you can access values via numeric index.

qreal x = reading->value(0).value<qreal>();

Note that can only access properties declared with Q_PROPERTY() in sub-classes of QSensorReading .

valueCount() property()

PySide2.QtSensors.QSensorReading.valueCount()

Return type

int

Returns the number of extra properties that the reading has.

Note that this does not count properties declared in QSensorReading .

As an example, this returns 3 for QAccelerometerReading because there are 3 properties defined in that class.
