Detailed Description#
The path is defined by an ordered list of QGeoCoordinate
objects.
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.
- class PySide6.QtPositioning.QGeoPath#
PySide6.QtPositioning.QGeoPath(other)
PySide6.QtPositioning.QGeoPath(other)
PySide6.QtPositioning.QGeoPath(path[, width=0.0])
- Parameters:
other –
PySide6.QtPositioning.QGeoPath
path – .list of QGeoCoordinate
width – float
Constructs a new, empty geo path.
Constructs a new geo path from the contents of other
.
Constructs a new geo path from the contents of other
.
Constructs a new geo path from a list of coordinates (path
and width
).
Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.
- property PᅟySide6.QtPositioning.QGeoPath.path: list of QVariant#
This property holds This property holds the list of coordinates for the geo path..
Note
The coordinates cannot be processed in place. To change the value of this property, retrieve the complete list of coordinates, process them, and assign the new value to the property.
- Access functions:
variantPath
()setVariantPath
(path)
- property PᅟySide6.QtPositioning.QGeoPath.width: float#
This property holds the width of the path in meters..
- PySide6.QtPositioning.QGeoPath.addCoordinate(coordinate)#
- Parameters:
coordinate –
PySide6.QtPositioning.QGeoCoordinate
Appends coordinate
to the path.
- PySide6.QtPositioning.QGeoPath.clearPath()#
Clears the path.
- PySide6.QtPositioning.QGeoPath.containsCoordinate(coordinate)#
- Parameters:
coordinate –
PySide6.QtPositioning.QGeoCoordinate
- Return type:
bool
Returns true if the path contains coordinate
as one of the elements.
- PySide6.QtPositioning.QGeoPath.coordinateAt(index)#
- Parameters:
index – int
- Return type:
Returns the coordinate at index
.
- PySide6.QtPositioning.QGeoPath.insertCoordinate(index, coordinate)#
- Parameters:
index – int
coordinate –
PySide6.QtPositioning.QGeoCoordinate
Inserts coordinate
at the specified index
.
- PySide6.QtPositioning.QGeoPath.length([indexFrom=0[, indexTo=-1]])#
- Parameters:
indexFrom – int
indexTo – int
- Return type:
float
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
.
- PySide6.QtPositioning.QGeoPath.path()#
- Return type:
.list of QGeoCoordinate
Returns all the elements of the path.

from the path.
- PySide6.QtPositioning.QGeoPath.removeCoordinate(index)
- Parameters:
index – int
Removes element at position index
from the path.
- PySide6.QtPositioning.QGeoPath.replaceCoordinate(index, coordinate)#
- Parameters:
index – int
coordinate –
PySide6.QtPositioning.QGeoCoordinate
Replaces the path element at the specified index
with coordinate

- PySide6.QtPositioning.QGeoPath.size()#
- Return type:
int
Returns the number of elements in the path.
- PySide6.QtPositioning.QGeoPath.translate(degreesLatitude, degreesLongitude)#
- Parameters:
degreesLatitude – float
degreesLongitude – float
Translates this geo path by degreesLatitude
northwards and degreesLongitude
eastwards.
Negative values of degreesLatitude
and degreesLongitude
correspond to southward and westward translation respectively.

- Parameters:
degreesLatitude – float
degreesLongitude – float
- Return type:
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.
