QGeoManeuver ¶

概要 ¶

详细描述 ¶

QGeoRouteSegment instances can be thought of as edges on a routing graph, with QGeoManeuver instances as optional labels attached to the vertices of the graph.

The most interesting information help in a QGeoManeuver instance is normally the textual navigation to provide and the position at which to provide it, accessible by instructionText() and position() 分别。

It is also possible to determine if a routing waypoint has been passed by checking if waypoint() returns a valid QGeoCoordinate .

class QGeoManeuver ¶

QGeoManeuver(other)

param other

QGeoManeuver

Constructs a invalid maneuver object.

The maneuver will remain invalid until one of setPosition() , setInstructionText() , setDirection() , setTimeToNextInstruction() , setDistanceToNextInstruction() or setWaypoint() 被调用。

PySide2.QtLocation.QGeoManeuver. InstructionDirection ¶

Describes the change in direction associated with the instruction text that is associated with a QGeoManaeuver.

QGeoManeuver.DirectionBearRight	The instruction indicates that the direction of travel should bear to the right.
QGeoManeuver.DirectionLightRight	The instruction indicates that a light turn to the right is required.
QGeoManeuver.DirectionRight	The instruction indicates that a turn to the right is required.
QGeoManeuver.DirectionHardRight	The instruction indicates that a hard turn to the right is required.
QGeoManeuver.DirectionUTurnRight	The instruction indicates that a u-turn to the right is required.
QGeoManeuver.DirectionUTurnLeft	The instruction indicates that a u-turn to the left is required.
QGeoManeuver.DirectionHardLeft	The instruction indicates that a hard turn to the left is required.
