QGeoRouteSegment ¶

概要 ¶

详细描述 ¶

A QGeoRouteSegment instance has information about the physical layout of the route segment, the length of the route and estimated time required to traverse the route segment and an optional QGeoManeuver associated with the beginning of the route segment.

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.

class QGeoRouteSegment ¶

QGeoRouteSegment(other)

param other

QGeoRouteSegment

Constructs an invalid route segment object.

The route segment will remain invalid until one of setNextRouteSegment() , setTravelTime() , setDistance() , setPath() or setManeuver() 被调用。

Constructs a route segment object from the contents of other .

PySide2.QtLocation.QGeoRouteSegment. distance ( ) ¶

返回类型

qreal

Returns the distance covered by this segment of the route, in meters.

setDistance()

PySide2.QtLocation.QGeoRouteSegment. isLegLastSegment ( ) ¶

返回类型

bool

Returns whether this route segment is the last segment of a route leg.

PySide2.QtLocation.QGeoRouteSegment. isValid ( ) ¶

返回类型

bool

Returns whether this route segment is valid or not.

若 nextRouteSegment() is called on the last route segment of a route, the returned value will be an invalid route segment.

PySide2.QtLocation.QGeoRouteSegment. maneuver ( ) ¶

返回类型

QGeoManeuver

Returns the maneuver for this route segment.

Will return an invalid QGeoManeuver if no information has been attached to the starting point of this route segment.

PySide2.QtLocation.QGeoRouteSegment. nextRouteSegment ( ) ¶

返回类型

QGeoRouteSegment

Returns the next route segment in the route.

Will return an invalid route segment if this is the last route segment in the route.

参数

other – QGeoRouteSegment

返回类型

bool

参数

other – QGeoRouteSegment

返回类型

bool

Returns whether this route segment and other are equal.

值 nextRouteSegment() is not considered in the comparison.
