Constructor & Destructor Documentation

◆ QGeoMapPolygonGeometry()

QT_BEGIN_NAMESPACE QGeoMapPolygonGeometry::QGeoMapPolygonGeometry ( )

default

\qmltype MapPolygon \instantiates QDeclarativePolygonMapItem \inqmlmodule QtLocation

Since: QtLocation 5.5

The MapPolygon type displays a polygon on a Map.

The MapPolygon type displays a polygon on a Map, specified in terms of an ordered list of \l {QtPositioning::coordinate}{coordinates}. For best appearance and results, polygons should be simple (not self-intersecting).

The \l {QtPositioning::coordinate}{coordinates} on the path cannot be directly changed after being added to the Polygon. Instead, copy the \l path into a var, modify the copy and reassign the copy back to the \l path.

var path = mapPolygon.path;
path[0].latitude = 5;
mapPolygon.path = path;

Coordinates can also be added and removed at any time using the \l addCoordinate and \l removeCoordinate methods.

For drawing rectangles with "straight" edges (same latitude across one edge, same latitude across the other), the \l MapRectangle type provides a simpler, two-point API.

By default, the polygon is displayed as a 1 pixel black border with no fill. To change its appearance, use the \l color, \l border.color and \l border.width properties.

Note: Since MapPolygons are geographic items, dragging a MapPolygon (through the use of \l MouseArea or \l PointHandler) causes its vertices to be recalculated in the geographic coordinate space. The edges retain the same geographic lengths (latitude and longitude differences between the vertices), but they remain straight. Apparent stretching of the item occurs when dragged to a different latitude.
