詳細描述

The QPressureReading class holds readings from the pressure sensor.

QPressureReading Units

The pressure sensor returns atmospheric pressure values in Pascals.

特性文檔編製

pressure : const qreal

This property holds the measured atmospheric pressure.

Returned as Pascals.

訪問函數：

qreal

pressure () const

另請參閱 QPressureReading Units .

temperature : const qreal

This property holds the pressure sensor's temperature.

The temperature is returned in degree Celsius. This property, if supported, provides the pressure sensor die temperature. Note that this temperature may be (and usually is) different than the temperature reported from QAmbientTemperatureSensor 。使用 QSensor::isFeatureSupported () 采用 QSensor::PressureSensorTemperature flag to determine its availability.

該特性在 Qt 5.2 引入。

成員函數文檔編製

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

Default constructs an instance of QPressureReading.

[虛擬] QPressureReading:: ~QPressureReading ()

Destroys the instance of QPressureReading. The destructor is virtual.

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

void QPressureReading:: setPressure ( qreal pressure )

Sets the pressure to pressure .

另請參閱 pressure ().

void QPressureReading:: setTemperature ( qreal temperature )

Sets the pressure sensor's temperature to temperature .

該函數在 Qt 5.2 引入。
