QRotationSensor Class

The QRotationSensor class is a convenience wrapper around QSensor. More...

Header: #include <QRotationSensor>
qmake: QT += sensors
Since: Qt 5.1
Inherits: QSensor

This class was introduced in Qt 5.1.

Properties

Public Functions

QRotationSensor(QObject *parent = Q_NULLPTR)
virtual ~QRotationSensor()
bool hasZ() const
QRotationReading * reading() const
void setHasZ(bool hasZ)

Signals

void hasZChanged(bool hasZ)

Detailed Description

The only behavioural difference is that this class sets the type properly.

This class also features a reading() function that returns a QRotationReading instead of a QSensorReading.

For details about how the sensor works, see QRotationReading.

See also QRotationReading.

Property Documentation

hasZ : const bool

This property holds a value indicating if the z angle is available.

Returns true if z is available. Returns false if z is not available.

Access functions:

bool hasZ() const

Notifier signal:

void hasZChanged(bool hasZ)

Member Function Documentation

QRotationSensor::QRotationSensor(QObject *parent = Q_NULLPTR)

Construct the sensor as a child of parent.

[virtual] QRotationSensor::~QRotationSensor()

Destroy the sensor. Stops the sensor if it has not already been stopped.

QRotationReading *QRotationSensor::reading() const

Returns the reading class for this sensor.

See also QSensor::reading().

void QRotationSensor::setHasZ(bool hasZ)

Sets whether the z angle is available to hasZ. This is to be called from the backend. By default the hasZ property is true, so a backend only has to call this if its rotation sensor can not report z angles.

This function was introduced in Qt 5.1.

See also hasZ().
