详细描述
The QDistanceSensor class is a convenience wrapper around QSensor.
The only behavioral difference is that this class sets the type properly.
This class also features a reading() function that returns a QDistanceReading instead of a QSensorReading.
For details about how the sensor works, see QDistanceReading.
参见 QDistanceReading.
成员函数
QDistanceSensor::QDistanceSensor(QObject *parent = Q_NULLPTR)
Construct the sensor as a child of parent.
QDistanceSensor::~QDistanceSensor()
Destroy the sensor. Stops the sensor if it has not already been stopped.
QDistanceReading *QDistanceSensor::reading() const
Returns the reading class for this sensor.
参见 QSensor::reading().
