Known Implementations

ChamplainLocation is implemented by ChamplainCoordinate, ChamplainCustomMarker, ChamplainLabel, ChamplainMarker and ChamplainPoint.

Description

By implementing ChamplainLocation the object declares that it has latitude and longitude and can be used to specify location on the map.

Functions

champlain_location_set_location ()

void
champlain_location_set_location (ChamplainLocation *location,
                                 gdouble latitude,
                                 gdouble longitude);

Sets the coordinates of the location

Parameters

location	a ChamplainLocation
latitude	the latitude
longitude	the longitude

Since: 0.10

champlain_location_get_latitude ()

gdouble
champlain_location_get_latitude (ChamplainLocation *location);

Gets the latitude coordinate.

Parameters

location

a ChamplainLocation

Returns

the latitude coordinate.

champlain_location_get_longitude ()

gdouble
champlain_location_get_longitude (ChamplainLocation *location);

Gets the longitude coordinate.

Parameters

location

a ChamplainLocation

Returns

the longitude coordinate.

Since: 0.10

Types and Values

struct ChamplainLocationIface

struct ChamplainLocationIface {
  gdouble (*get_latitude)(ChamplainLocation *location);
  gdouble (*get_longitude)(ChamplainLocation *location);
  void (*set_location)(ChamplainLocation *location,
      gdouble latitude,
      gdouble longitude);
