Display paths

_{Estimated reading time: 1 minute}

Paths can be displayed by adding them into MapViewPathCollection. The MapViewPathCollection is an iterable collection, having fields like size, add, remove, removeAt, getPathAt and getPathByName.

mapController.preferences.paths.add(path);

The add method of MapViewPathCollection includes optional parameters for customizing the appearance of paths on the map, such as colorBorder, colorInner, szBorder, and szInner. To center the map on a path, use the GemMapController.centerOnArea() method with the path's area retrieved from the area getter.

mapController.preferences.paths.add(path);

mapController.centerOnArea(path.area);

Path displayed

To remove all paths from GemMap use MapViewPathCollection.clear(). To remove selectively, use MapViewPathCollection.remove(path) or MapViewPathCollection.removeAt(index).
