+
+ \brief The QGeoPath class defines a geographic path.
+
+ The path is defined by an ordered list of QGeoCoordinates.
+
+ 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
+ \l QGeoShape::geoBoundingBox() 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 \l Q_GADGET.
+ It can be \l{Cpp_value_integration_positioning}{directly used from C++ and QML}.
