Detailed Description

The QGeoManeuver class represents the information relevant to the point at which two QGeoRouteSegments meet.

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 Type Documentation

enum QGeoManeuver::InstructionDirection

Describes the change in direction associated with the instruction text that is associated with a QGeoManaeuver.

ConstantValueDescription
QGeoManeuver::NoDirection0There is no direction associated with the instruction text.
QGeoManeuver::DirectionForward1The instruction indicates that the direction of travel does not need to change.
QGeoManeuver::DirectionBearRight2The instruction indicates that the direction of travel should bear to the right.
QGeoManeuver::DirectionLightRight3The instruction indicates that a light turn to the right is required.
QGeoManeuver::DirectionRight4The instruction indicates that a turn to the right is required.
QGeoManeuver::DirectionHardRight5The instruction indicates that a hard turn to the right is required.
QGeoManeuver::DirectionUTurnRight6The instruction indicates that a u-turn to the right is required.
QGeoManeuver::DirectionUTurnLeft7The instruction indicates that a u-turn to the left is required.
QGeoManeuver::DirectionHardLeft8The instruction indicates that a hard turn to the left is required.
QGeoManeuver::DirectionLeft9The instruction indicates that a turn to the left is required.
QGeoManeuver::DirectionLightLeft10The instruction indicates that a light turn to the left is required.
QGeoManeuver::DirectionBearLeft11The instruction indicates that the direction of travel should bear to the left.

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.

This function was introduced in Qt Mobility 1.1.

QGeoManeuver::~QGeoManeuver ()

Destroys this manevuer object.

InstructionDirection QGeoManeuver::direction () const

Returns the direction associated with the associated instruction.

This function was introduced in Qt Mobility 1.1.

See also setDirection().

qreal QGeoManeuver::distanceToNextInstruction () const

Returns the distance, in metres, between the point at which the associated instruction was issued and the point that the next instruction should be issued.

This function was introduced in Qt Mobility 1.1.

See also setDistanceToNextInstruction().

QString QGeoManeuver::instructionText () const

Returns the textual navigation instructions.

This function was introduced in Qt Mobility 1.1.

See also setInstructionText().

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.

This function was introduced in Qt Mobility 1.1.

QGeoCoordinate QGeoManeuver::position () const

Returns the position where instructionText() should be displayed.

This function was introduced in Qt Mobility 1.1.

See also setPosition().

void QGeoManeuver::setDirection ( InstructionDirection direction )

Sets the direction associated with the associated instruction to direction.

This function was introduced in Qt Mobility 1.1.

See also direction().

void QGeoManeuver::setDistanceToNextInstruction ( qreal distance )

Sets the distance, in metres, between the point at which the associated instruction was issued and the point that the next instruction should be issued to distance.

This function was introduced in Qt Mobility 1.1.

See also distanceToNextInstruction().

void QGeoManeuver::setInstructionText ( const QString & instructionText )

Sets the textual navigation instructions to instructionText.

This function was introduced in Qt Mobility 1.1.

See also instructionText().

void QGeoManeuver::setPosition ( const QGeoCoordinate & position )

Sets the position where instructionText() should be displayed to position.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

See also timeToNextInstruction().

void QGeoManeuver::setWaypoint ( const QGeoCoordinate & coordinate )

Sets the waypoint associated with this maneuver to coordinate.

This function was introduced in Qt Mobility 1.1.

See also waypoint().

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.

This function was introduced in Qt Mobility 1.1.

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.

This function was introduced in Qt Mobility 1.1.

See also setWaypoint().

bool QGeoManeuver::operator!= ( const QGeoManeuver & other ) const

Returns whether this maneuver is not equal to other.

This function was introduced in Qt Mobility 1.1.

QGeoManeuver & QGeoManeuver::operator= ( const QGeoManeuver & other )

Assigns other to this maneuver object and then returns a reference to this maneuver object.

This function was introduced in Qt Mobility 1.1.

bool QGeoManeuver::operator== ( const QGeoManeuver & other ) const

Returns whether this maneuver is equal to other.

This function was introduced in Qt Mobility 1.1.
