概要 ¶

详细描述 ¶

唯一行为差异是此类正确设置类型。

It also supports changing the acceleration mode, which controls whether the force of gravity is included in the accelerometer values or not.

Furthermore, this class features a reading() function that returns a QAccelerometerReading 而不是 QSensorReading .

PySide2.QtSensors.QAccelerometer. AccelerationMode ¶

This enum represents the acceleration mode of an acceleration sensor.

The acceleration mode controls how the sensor reports acceleration. is the only mode in which the values can be directly physically measured, the others are an approximation.

常量	描述
QAccelerometer.Combined	Both the acceleration caused by gravity and the acceleration caused by the user moving the device is reported combined.
QAccelerometer.Gravity	Only the acceleration caused by gravity is reported. Movements of the device caused by the user have no effect other than changing the direction when the device is rotated.
QAccelerometer.User	Only the acceleration caused by the user moving the device is reported, the effect of gravity is canceled out. A device at rest therefore should report values of, or close to, zero. In other APIs, this mode might be known as linear acceleration .
