詳細描述

唯一行為差異是此類正確設置類型。

此類還特徵 reading () 函數返迴 QRotationReading 而不是 QSensorReading .

[read-only] 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.

訪問函數:

bool hasZ () const

通知程序信號:

void hasZChanged (bool hasZ )

[explicit] QRotationSensor:: QRotationSensor ( QObject * parent = nullptr)

構造傳感器作為子級對於 parent .

[虛擬] QRotationSensor:: ~QRotationSensor ()

銷毀傳感器。停止傳感器若尚未停止。

QRotationReading *QRotationSensor:: reading () const

返迴用於此傳感器的讀取類。

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.
