QGeoManeuver Class▲

Header: QGeoManeuver
-
Since: Qt 5.6
-
qmake: QT += location
-
Group: QGeoManeuver is part of QtLocation-routing
Detailed Description▲
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() respectively.
It is also possible to determine if a routing waypoint has been passed by checking if waypoint() returns a valid QGeoCoordinate.

Member Function Documentation▲
QGeoManeuver::QGeoManeuver()▲
Constructs a invalid maneuver object.
The maneuver will remain invalid until one of setPosition(), setInstructionText(), setDirection(), setTimeToNextInstruction(), setDistanceToNextInstruction() or setWaypoint() is called.
QGeoManeuver::QGeoManeuver(const QGeoManeuver &other)▲
Constructs a maneuver object from the contents of other.
QGeoManeuver::~QGeoManeuver()▲
Destroys this maneuver object.
QGeoManeuver::InstructionDirection QGeoManeuver::direction() const▲
qreal QGeoManeuver::distanceToNextInstruction() const▲
Returns the distance, in meters, between the point at which the associated instruction was issued and the point that the next instruction should be issued.
See Also▲
See also setDistanceToNextInstruction()
[since QtLocation 5.11] QVariantMap QGeoManeuver::extendedAttributes() const▲
Returns the extended attributes associated with this maneuver.
This function was introduced in QtLocation 5.11.
See Also▲
See also setExtendedAttributes()
QString QGeoManeuver::instructionText() const▲
bool QGeoManeuver::isValid() const▲
Returns whether this maneuver is valid or not.
Invalid maneuvers are used when there is no information that needs to be attached to the endpoint of a QGeoRouteSegment instance.
QGeoCoordinate QGeoManeuver::position() const▲
void QGeoManeuver::setDirection(QGeoManeuver::InstructionDirection direction)▲
Sets the direction associated with the associated instruction to direction.
See Also▲
See also direction()
void QGeoManeuver::setDistanceToNextInstruction(qreal distance)▲
Sets the distance, in meters, between the point at which the associated instruction was issued and the point that the next instruction should be issued to distance.
See Also▲
See also distanceToNextInstruction()
[since QtLocation 5.11] void QGeoManeuver::setExtendedAttributes(const QVariantMap &extendedAttributes)▲
Sets the extended attributes extendedAttributes associated with this maneuver.
This function was introduced in QtLocation 5.11.
See Also▲
See also extendedAttributes()
void QGeoManeuver::setInstructionText(const QString &instructionText)▲
void QGeoManeuver::setPosition(const QGeoCoordinate &position)▲
Sets the position where instructionText() should be displayed to position.
See Also▲
See also position()
void QGeoManeuver::setTimeToNextInstruction(int secs)▲
Sets the estimated time it will take to travel from the point at which the associated instruction was issued and the point that the next instruction should be issued, in seconds, to secs.
See Also▲
See also timeToNextInstruction()
void QGeoManeuver::setWaypoint(const QGeoCoordinate &coordinate)▲
int QGeoManeuver::timeToNextInstruction() const▲
Returns the estimated time it will take to travel from the point at which the associated instruction was issued and the point that the next instruction should be issued, in seconds.
See Also▲
See also setTimeToNextInstruction()
QGeoCoordinate QGeoManeuver::waypoint() const▲
Returns the waypoint associated with this maneuver.
If there is not waypoint associated with this maneuver an invalid QGeoCoordinate will be returned.
See Also▲

bool QGeoManeuver::operator!=(const QGeoManeuver &other) const▲
Returns whether this maneuver is not equal to other.
QGeoManeuver &QGeoManeuver::operator=(const QGeoManeuver &other)▲
Assigns other to this maneuver object and then returns a reference to this maneuver object.
bool QGeoManeuver::operator==(const QGeoManeuver &other) const▲
Returns whether this maneuver is equal to other.
