详细描述
The QGeoRoute class represents a route between two points.
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()
成员函数
QGeoRoute::QGeoRoute()
Constructs a route object.
QGeoRoute::QGeoRoute(const QGeoRoute &other)
Constructs a route object from the contents of other.
QGeoRoute::~QGeoRoute()
Destroys this route object.
QGeoRectangle QGeoRoute::bounds() const
Returns a bounding box which encompasses the entire route.
参见 setBounds().
qreal QGeoRoute::distance() const
Returns the distance covered by this route, in meters.
参见 setDistance().
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.
参见 setFirstRouteSegment().
QList<QGeoCoordinate> QGeoRoute::path() const
Returns 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.
参见 setPath().
QGeoRouteRequest QGeoRoute::request() const
Returns the route request which describes the criteria used in the calculation of this route.
参见 setRequest().
QString QGeoRoute::routeId() const
Returns the identifier of this route.
Service providers which support the updating of routes commonly assign identifiers to routes. If this route did not come from such a service provider the function will return an empty string.
参见 setRouteId().
void QGeoRoute::setBounds(const QGeoRectangle &bounds)
Sets the bounding box which encompasses the entire route to bounds.
参见 bounds().
void QGeoRoute::setDistance(qreal distance)
Sets the distance covered by this route, in meters, to distance.
参见 distance().
void QGeoRoute::setFirstRouteSegment(const QGeoRouteSegment &routeSegment)
Sets the first route segment in the route to routeSegment.
参见 firstRouteSegment().
void QGeoRoute::setPath(const QList<QGeoCoordinate> &path)
Sets the geometric shape of the route to path.
The coordinates in path should be listed in the order in which they would be traversed by someone traveling along this segment of the route.
参见 path().
void QGeoRoute::setRequest(const QGeoRouteRequest &request)
Sets the route request which describes the criteria used in the calculcation of this route to request.
参见 request().
void QGeoRoute::setRouteId(const QString &id)
Sets the identifier of this route to id.
Service providers which support the updating of routes commonly assign identifiers to routes. If this route came from such a service provider changing the identifier will probably cause route updates to stop working.
参见 routeId().
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().
参见 travelMode().
void QGeoRoute::setTravelTime(int secs)
Sets the estimated amount of time it will take to traverse this route, in seconds, to secs.
参见 travelTime().
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().
参见 setTravelMode().
int QGeoRoute::travelTime() const
Returns the estimated amount of time it will take to traverse this route, in seconds.
参见 setTravelTime().
bool QGeoRoute::operator!=(const QGeoRoute &other) const
Returns whether this route and other are not equal.
QGeoRoute &QGeoRoute::operator=(const QGeoRoute &other)
Assigns the contents of other to this route and returns a reference to this route.
bool QGeoRoute::operator==(const QGeoRoute &other) const
Returns whether this route and other are equal.
