The QLightSensor class is a convenience wrapper around QSensor. More...
|CMake:|| find_package(Qt6 REQUIRED COMPONENTS Sensors) |
target_link_libraries(mytarget PRIVATE Qt6::Sensors)
|qmake:||QT += sensors|
- fieldOfView : const qreal
|QLightSensor(QObject *parent = nullptr)|
|QLightReading *||reading() const|
The only behavioural difference is that this class sets the type properly.
This class also features a reading() function that returns a QLightReading instead of a QSensorReading.
For details about how the sensor works, see QLightReading.
See also QLightReading.
[read-only] fieldOfView : const qreal
This property holds a value indicating the field of view.
This is an angle that represents the field of view of the sensor.
Not all light sensor support retrieving their field of view. For sensors that don't support this property, the value will be 0. Whether the field of view is supported can be checked with QSensor::isFeatureSupported() and the QSensor::FieldOfView flag.
Member Function Documentation
[explicit] QLightSensor::QLightSensor(QObject *parent = nullptr)

Destroy the sensor. Stops the sensor if it has not already been stopped.
QLightReading *QLightSensor::reading() const
Returns the reading class for this sensor.
See also QSensor::reading().
void QLightSensor::setFieldOfView(qreal fieldOfView)
Sets the field of view to fieldOfView. This is to be called from the backend.
