Synopsis

Functions

Detailed Description

The path is defined by an ordered list of QGeoCoordinates.

Each two adjacent elements in the path are intended to be connected together by the shortest line segment of constant bearing passing through both elements. This type of connection can cross the dateline in the longitudinal direction, but never crosses the poles.

This is relevant for the calculation of the bounding box returned by boundingGeoRectangle() for this shape, which will have the latitude of the top left corner set to the maximum latitude in the path point set. Similarly, the latitude of the bottom right corner will be the minimum latitude in the path point set.

This class is a Q_GADGET . It can be directly used from C++ and QML .

A QGeoPath is both invalid and empty if it contains no coordinate.

Note

A default constructed QGeoPath is both invalid and empty as it does not contain any coordinates.

qreal

Constructs a new, empty geo path.

Constructs a new geo path from a list of coordinates (path and width ).

PySide2.QtPositioning.QGeoPath.addCoordinate(coordinate)
Parameters

coordinateQGeoCoordinate

Appends coordinate to the path.

PySide2.QtPositioning.QGeoPath.clearPath()

Clears the path.

PySide2.QtPositioning.QGeoPath.containsCoordinate(coordinate)
Parameters

coordinateQGeoCoordinate

Return type

bool

Returns true if the path contains coordinate as one of the elements.

PySide2.QtPositioning.QGeoPath.coordinateAt(index)
Parameters

indexint

Return type

QGeoCoordinate

Returns the coordinate at index .

PySide2.QtPositioning.QGeoPath.insertCoordinate(index, coordinate)
Parameters

Inserts coordinate at the specified index .

PySide2.QtPositioning.QGeoPath.length([indexFrom=0[, indexTo=-1]])
Parameters
  • indexFromint

  • indexToint

Return type

double

Returns the length of the path, in meters, from the element indexFrom to the element indexTo . The length is intended to be the sum of the shortest distances for each pair of adjacent points.

If indexTo is -1 (the default value), the length will be including the distance between last coordinate and the first (closed loop). To retrieve the length for the path, use 0 for indexFrom and size() - 1 for indexTo .

PySide2.QtPositioning.QGeoPath.__ne__(other)
Parameters

otherQGeoPath

Return type

bool

Returns whether this geo path is not equal to other .

PySide2.QtPositioning.QGeoPath.__eq__(other)
Parameters

otherQGeoPath

Return type

bool

Returns whether this geo path is equal to other .

PySide2.QtPositioning.QGeoPath.path()
Return type

Returns all the elements of the path.

width()

PySide2.QtPositioning.QGeoPath.size()
Return type

int

Returns the number of elements in the path.

PySide2.QtPositioning.QGeoPath.translate(degreesLatitude, degreesLongitude)
Parameters
  • degreesLatitudedouble

  • degreesLongitudedouble

Translates this geo path by degreesLatitude northwards and degreesLongitude eastwards.

Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.

PySide2.QtPositioning.QGeoPath.translated(degreesLatitude, degreesLongitude)
Parameters
  • degreesLatitudedouble

  • degreesLongitudedouble

Return type

QGeoPath

Returns a copy of this geo path translated by degreesLatitude northwards and degreesLongitude eastwards.

Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.

PySide2.QtPositioning.QGeoPath.variantPath()
Return type

Returns all the elements of the path.

PySide2.QtPositioning.QGeoPath.width()
Return type

qreal

Returns the width of the path, in meters. This information is used in the contains method. The default value is 0.
