target_link_libraries(mytarget PRIVATE Qt6::Sensors)
qmake: QT += sensors
继承自: QSensorFilter

公共函数

virtual bool filter(QCompassReading *reading) = 0

详细说明

唯一的区别在于,filter() 方法使用的指针指向QCompassReading ,而不是QSensorReading 。

成员函数文档

[pure virtual] bool QCompassFilter::filter(QCompassReading *reading)

当reading 发生变化时调用。返回false可阻止该读取操作传播。
