详细描述

A QGeoRoute object contains high level information about a route, such as the length the route, the estimated travel time for the route, and enough information to render a basic image of the route on a map.

The QGeoRoute object also contains a list of QGeoRouteSegment objecs which describe subsections of the route in greater detail.

Routing information is normally requested using QGeoRoutingManager::calculateRoute (), which returns a QGeoRouteReply instance. If the operation is completed successfully the routing information can be accessed with QGeoRouteReply::routes ()

另请参阅 QGeoRoutingManager .

[read-only] bounds : const QGeoRectangle

This property holds the bounding box which encompasses the entire route

访问函数：

QGeoRectangle

bounds () const

[read-only] distance : const qreal

This property holds the distance covered by this route, in meters

访问函数：

qreal

distance () const

[read-only] extendedAttributes : const QVariantMap

This property holds the extended attributes associated with this route

访问函数：

QVariantMap

extendedAttributes () const

[read-only] legIndex : const int

This property holds the leg index of this route

The index of the leg inside the containing QGeoRoute::routeLegs list can be used to find the next legs.

访问函数：

int	legIndex () const

[read-only] overallRoute : const QGeoRoute

This property holds the route that contains this route leg

This this route is not a leg within an overall route, then this property holds an empty route.

访问函数：

QGeoRoute

overallRoute () const

path : QList < QGeoCoordinate >

This property holds the geometric shape of the route

The coordinates should be listed in the order in which they would be traversed by someone traveling along this segment of the route.

访问函数：

QList<QGeoCoordinate>	path () const
void	setPath (const QList<QGeoCoordinate> & path )

[read-only] routeId : const QString

This property holds the identifier of this route

Service providers which support the updating of routes commonly assign identifiers to routes. If this route came from such a service provider, then changing the identifier will probably cause route updates to stop working.

访问函数：

QString

routeId () const

[read-only] routeLegs : const QList < QGeoRoute >

This property holds the route legs for a multi-waypoint route

访问函数：

QList<QGeoRoute>

routeLegs () const

[read-only] segments : const QList < QGeoRouteSegment >

This property holds the list of QGeoRouteSegment objects of this route

访问函数：

QList<QGeoRouteSegment>

segments () const

[read-only] segmentsCount : const qsizetype

This property holds the number of segments in the route

访问函数：

qsizetype

segmentsCount () const

[read-only] travelTime : const int

This property holds the estimated amount of time it will take to traverse this route, in seconds

访问函数：

int	travelTime () const

QGeoRoute:: QGeoRoute ()

Constructs a route object.

[noexcept] QGeoRoute:: QGeoRoute (const QGeoRoute & other )

Constructs a route object from the contents of other .

[noexcept] QGeoRoute:: ~QGeoRoute ()

Destroys this route object.

[protected] QExplicitlySharedDataPointer < QGeoRoutePrivate > &QGeoRoute:: d ()

Returns the private implementation.

QGeoRouteSegment QGeoRoute:: firstRouteSegment () const

Returns the first route segment in the route.

Will return an invalid route segment if there are no route segments associated with the route.

The remaining route segments can be accessed sequentially with QGeoRouteSegment::nextRouteSegment .

另请参阅 setFirstRouteSegment ().

void QGeoRoute:: setFirstRouteSegment (const QGeoRouteSegment & routeSegment )

Sets the first route segment in the route to routeSegment .

另请参阅 firstRouteSegment ().

void QGeoRoute:: setTravelMode ( QGeoRouteRequest::TravelMode mode )

Sets the travel mode for this route to mode .

This should be one of the travel modes returned by request().travelModes().

另请参阅 travelMode ().

QGeoRouteRequest::TravelMode QGeoRoute:: travelMode () const

Returns the travel mode for the this route.

This should be one of the travel modes returned by request().travelModes().

另请参阅 setTravelMode ().

[noexcept] QGeoRoute &QGeoRoute:: operator= (const QGeoRoute & other )

Assigns the contents of other to this route and returns a reference to this route.

相关非成员

[noexcept] bool operator!= (const QGeoRoute & lhs , const QGeoRoute & rhs )

Returns whether the routes lhs and rhs are not equal.

[noexcept] bool operator== (const QGeoRoute & lhs , const QGeoRoute & rhs )

Returns whether the routes lhs and rhs 相等。
