QGeoPolygon::~QGeoPolygon()

Destroys this polygon.

void QGeoPolygon::addCoordinate(const QGeoCoordinate &coordinate)

Appends coordinate to the polygon.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QGeoPolygon::addHole(const QVariant &holePath)

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

This function was introduced in Qt 5.12.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QGeoPolygon::addHole(const QList<QGeoCoordinate> &holePath)

Overloaded method. Sets the path for a hole inside the polygon. The hole is a QList<QGeoCoordinate>.

This function was introduced in Qt 5.12.

bool QGeoPolygon::containsCoordinate(const QGeoCoordinate &coordinate) const

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

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

QGeoCoordinate QGeoPolygon::coordinateAt(int index) const

Returns the coordinate at index .

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

const QVariantList QGeoPolygon::hole(int index) const

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

This function was introduced in Qt 5.12.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

const QList<QGeoCoordinate> QGeoPolygon::holePath(int index) const

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

This function was introduced in Qt 5.12.

int QGeoPolygon::holesCount() const

Returns the number of holes.

This function was introduced in Qt 5.12.

double QGeoPolygon::length(int indexFrom = 0, int indexTo = -1) const

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.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

const QList<QGeoCoordinate> &QGeoPolygon::path() const

Returns all the elements of the polygon's boundary.
