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 .

- 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 –

- Return type:
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:
