PySide2.QtPositioning.QGeoPositionInfo. 属性 ¶

Defines the attributes for positional information.

常量	描述
QGeoPositionInfo.Direction	The bearing measured in degrees clockwise from true north to the direction of travel.
QGeoPositionInfo.GroundSpeed	The ground speed, in meters/sec.
QGeoPositionInfo.VerticalSpeed	The vertical speed, in meters/sec.
QGeoPositionInfo.MagneticVariation	The angle between the horizontal component of the magnetic field and true north, in degrees. Also known as magnetic declination. A positive value indicates a clockwise direction from true north and a negative value indicates a counter-clockwise direction.
