Detailed Description

The QGeoRouteRequest class represents the parameters and restrictions which define a request for routing information.

The default state of a QGeoRouteRequest instance will result in a request for basic route segment and navigation maneuvers describing the fastest route by car which covers the given waypoints.

There may be significant variation in the features supported by different providers of routing information, or even in the features supported by the same provider if different levels of authorization are used.

There are several functions in QGeoRoutingManager which can be used to check which features are supported with the current provider and authorization level.

See also QGeoRoutingManager.

enum QGeoRouteRequest::FeatureWeightflags QGeoRouteRequest::FeatureWeights

QGeoRouteRequest::NeutralFeatureWeight	0x00000000	The presence or absence of the feature will not affect the planning of the route.
QGeoRouteRequest::PreferFeatureWeight	0x00000001	Routes which contain the feature will be preferred over those that do not.

The FeatureWeights type is a typedef for QFlags<FeatureWeight>. It stores an OR combination of FeatureWeight values.

enum QGeoRouteRequest::ManeuverDetailflags QGeoRouteRequest::ManeuverDetails

Defines the amount of maneuver information that should be included with the route.

QGeoRouteRequest::FastestRoute	0x0002	Minimize the traveling time for the journey.
QGeoRouteRequest::MostEconomicRoute	0x0004	Minimize the cost of the journey.
QGeoRouteRequest::MostScenicRoute	0x0008	Maximize the scenic potential of the journey.

The RouteOptimizations type is a typedef for QFlags<RouteOptimization>. It stores an OR combination of RouteOptimization values.

enum QGeoRouteRequest::SegmentDetailflags QGeoRouteRequest::SegmentDetails

Defines the amount of route segment information that should be included with the route.

Constant	Value	Description
QGeoRouteRequest::NoSegmentData	0x0000	No segment data should be included with the route. A route requested with this level of segment detail will initialize QGeoRouteSegment::path() as a straight line between the positions of the previous and next QGeoManeuver instances.
QGeoRouteRequest::BasicSegmentData	0x0001	Basic segment data will be included with the route. This will include QGeoRouteSegment::path().

The SegmentDetails type is a typedef for QFlags<SegmentDetail>. It stores an OR combination of SegmentDetail values.

enum QGeoRouteRequest::TravelModeflags QGeoRouteRequest::TravelModes

Defines modes of travel to be used for a route.

Constant	Value	Description
QGeoRouteRequest::CarTravel	0x0001	The route will be optimized for someone who is driving a car.
QGeoRouteRequest::PedestrianTravel	0x0002	The route will be optimized for someone who is walking.
QGeoRouteRequest::BicycleTravel	0x0004	The route will be optimized for someone who is riding a bicycle.

QGeoRouteRequest::TruckTravel	0x0010	The route will be optimized for someone who is driving a truck.

The TravelModes type is a typedef for QFlags<TravelMode>. It stores an OR combination of TravelMode values.

Member Function Documentation

QGeoRouteRequest::QGeoRouteRequest(const QList<QGeoCoordinate> &waypoints = QList<QGeoCoordinate> ())

Constructs a request to calculate a route through the coordinates waypoints.

The route will traverse the objects of waypoints in order.
