Synopsis

Functions

Detailed Description

The polygon is defined by an ordered list of QGeoCoordinates representing its perimeter.

Each two adjacent elements in this list 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 date line 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 .

Parameters

indexint

Return type

QGeoCoordinate

Returns the coordinate at index .

PySide2.QtPositioning.QGeoPolygon.hole(index)
Parameters

indexint

Return type

Returns a QVariant containing a QVariant containing a QList < QGeoCoordinate > which represents the hole at index.

Return type

int

Returns the number of elements in the polygon.

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

  • degreesLongitudedouble

Translates this geo polygon by degreesLatitude northwards and degreesLongitude eastwards.

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

Parameters
  • degreesLatitudedouble

  • degreesLongitudedouble

Return type

QGeoPolygon

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

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