Detailed Description

The polygon is defined by an ordered list of QGeoCoordinate objects 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 .

class PySide6.QtPositioning.QGeoPolygon

PySide6.QtPositioning.QGeoPolygon(other)

PySide6.QtPositioning.QGeoPolygon(other)

PySide6.QtPositioning.QGeoPolygon(path)

Parameters

• other – PySide6.QtPositioning.QGeoPolygon

• path –

Constructs a new, empty geo polygon.

Constructs a new geo polygon from the contents of other.

Constructs a new geo polygon from the contents of other.

PySide6.QtPositioning.QGeoPolygon.addCoordinate(coordinate)

Parameters

coordinate – PySide6.QtPositioning.QGeoCoordinate

Appends coordinate to the polygon.

PySide6.QtPositioning.QGeoPolygon.addHole(holePath)

Parameters

holePath –

PySide6.QtPositioning.QGeoPolygon.addHole(holePath)

Parameters

holePath – object

Sets the holePath for a hole inside the polygon. The hole is a QVariant containing a QList < QGeoCoordinate >.

PySide6.QtPositioning.QGeoPolygon.containsCoordinate(coordinate)

Parameters

coordinate – PySide6.QtPositioning.QGeoCoordinate

Return type

bool

Returns true if the polygon’s perimeter contains coordinate as one of the elements.

PySide6.QtPositioning.QGeoPolygon.coordinateAt(index)

Parameters

index – qsizetype

Return type

PySide6.QtPositioning.QGeoCoordinate

Returns the coordinate at index .

PySide6.QtPositioning.QGeoPolygon.hole(index)

Parameters

index – qsizetype

Return type

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

PySide6.QtPositioning.QGeoPolygon.holePath(index)

Parameters

index – qsizetype

Return type

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

PySide6.QtPositioning.QGeoPolygon.holesCount()

Return type

qsizetype

Returns the number of holes.

PySide6.QtPositioning.QGeoPolygon.insertCoordinate(index, coordinate)

Parameters

• index – qsizetype

• coordinate – PySide6.QtPositioning.QGeoCoordinate

Inserts coordinate at the specified index.

PySide6.QtPositioning.QGeoPolygon.length([indexFrom=0[, indexTo=-1]])

Parameters

• indexFrom – qsizetype

• indexTo – qsizetype

Return type

double

Returns the length of the polygon’s perimeter, 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.

PySide6.QtPositioning.QGeoPolygon.perimeter()

Return type

PySide6.QtPositioning.QGeoPolygon.removeCoordinate(index)

Parameters

index – qsizetype

Removes element at position index from the polygon.

PySide6.QtPositioning.QGeoPolygon.removeCoordinate(coordinate)

Parameters

coordinate – PySide6.QtPositioning.QGeoCoordinate

Removes the last occurrence of coordinate from the polygon.

PySide6.QtPositioning.QGeoPolygon.removeHole(index)

Parameters

index – qsizetype

Removes element at position index from the list of holes.

PySide6.QtPositioning.QGeoPolygon.replaceCoordinate(index, coordinate)

Parameters

• index – qsizetype

• coordinate – PySide6.QtPositioning.QGeoCoordinate

Replaces the path element at the specified index with coordinate.

PySide6.QtPositioning.QGeoPolygon.setPerimeter(path)

Parameters

path –

PySide6.QtPositioning.QGeoPolygon.size()

Return type

qsizetype

Returns the number of elements in the polygon.

PySide6.QtPositioning.QGeoPolygon.translate(degreesLatitude, degreesLongitude)

Parameters

• degreesLatitude – double

• degreesLongitude – double

Translates this geo polygon by degreesLatitude northwards and degreesLongitude eastwards.

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

PySide6.QtPositioning.QGeoPolygon.translated(degreesLatitude, degreesLongitude)

Parameters

• degreesLatitude – double

• degreesLongitude – double

Return type

PySide6.QtPositioning.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.
