GeoDeviceLocation

#include <bb/platform/geo/GeoDeviceLocation>

To link against this class, add the following line to your .pro file: LIBS += -lbbcascadesmaps

A point in geographic space that represents the device's current latitude and longitude coordinates.

The GeoDeviceLocation class uses Markers to indicate the device's current location on the map. It has two Marker properties, one used when the device has a valid heading, the other used when the device doesn't have a valid heading. Only one marker property is displayed at a time, depending on the headingValid property.

If no markers are provided, default ones will be used. (The defaults can be restored using the reset* operations.)

The deviceDirectionalMarker property is the Marker that is used to visually represent the device's location on a map when the direction of the device is known.

The icon for the marker is expected to point North initially, and is rotated in accordance with the device's heading. For example, if the heading is 90 degrees, then the icon is rotated a quarter turn to the right. The icon is rotated around the marker's "location coordinate" attribute (Marker::locationCoordinate()).

The deviceDirectionlessMarker property is the Marker that is used to visually represent the device's location on a map when the direction of the device is not known.

This marker is not rotated since it does not represent directionality.
