QPressureSensor Class
QPressureSensor 类是围绕QSensor 构建的一个便捷封装类。更多内容...
| 头文件： | #include <QPressureSensor> |
| CMake： | find_package(Qt6 REQUIRED COMPONENTS Sensors) target_link_libraries(mytarget PRIVATE Qt6::Sensors) |
| qmake： | QT += sensors |
| 继承自： | QSensor |
公共函数
| QPressureSensor(QObject *parent = nullptr) | |
| virtual | ~QPressureSensor() |
| QPressureReading * | reading() const |
详细说明
唯一的行为差异在于，该类会正确设置类型。
该类还提供了一个reading()函数，该函数返回的是QPressureReading ，而不是QSensorReading 。
有关传感器工作原理的详细信息，请参阅QPressureReading 。
另请参阅 QPressureReading 。
成员函数文档
[explicit] QPressureSensor::QPressureSensor(QObject *parent = nullptr)
将该传感器作为parent 的子节点进行构建。
[virtual noexcept] QPressureSensor::~QPressureSensor()
销毁传感器。如果传感器尚未停止运行，则将其停止。
QPressureReading *QPressureSensor::reading() const
返回该传感器的读取类。
