详细描述

QPressureReading class holds readings from the pressure sensor.

QPressureReading Units

The pressure sensor returns atmospheric pressure values in Pascals.

特性文档编制

pressure : const qreal

This property holds the measured atmospheric pressure.

Returned as Pascals.

访问函数：

qreal pressure () const

另请参阅 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.

该特性在 Qt 5.2 引入。

访问函数：

qreal temperature () const
