详细描述

The QHumidityReading class holds readings from the humidity sensor.

QHumidityReading Units

The humidity sensor returns the relative humidity as a percentage, and absolute humidity in grams per cubic meter (g/m3). Note that some sensors may not support absolute humidity, 0 will be returned in this case.

成员函数文档编制

QHumidityReading:: QHumidityReading ( QObject * parent = DECLARE_READING(QHumidityReading))

Default constructs an instance of QHumidityReading.

[虚拟] QHumidityReading:: ~QHumidityReading ()

Destroys the instance of QHumidityReading. The destructor is virtual.

[override virtual] void QHumidityReading:: copyValuesFrom ( QSensorReading * other )

void QHumidityReading:: setAbsoluteHumidity ( qreal value )

集 absoluteHumidity to value .

另请参阅 absoluteHumidity ().

void QHumidityReading:: setRelativeHumidity ( qreal humidity )

集 relativeHumidity to humidity .

另请参阅 relativeHumidity ().
