Map

The map UI component displays a geographic map. The default map data is provided by the OpenStreetMap project. For more information, see the Map API.

This feature is supported in mobile applications only.

Basic Usage

To use a map component in your application:

  1. Add a map with elm_map_add() function:

    Evas_Object *map;
Evas_Object *parent;

map = elm_map_add(parent);

  2. Set the zoom mode with the elm_map_zoom_mode_set() function:

    elm_map_zoom_mode_set(map, ELM_MAP_ZOOM_MODE_MANUAL);

  3. Set the zoom level with the elm_map_zoom_set() function:

    elm_map_zoom_set(map, 12);

  4. Show a specific area on the map based on coordinates using the elm_map_region_show() function:

    elm_map_region_show(map, 2.2, 48.8);

    To show a specific area with a bring-in animation, use the elm_map_region_bring_in() function:

    elm_map_region_bring_in(map, 2.2, 48.8);

  5. Register the callback functions.

    The following example shows how to define and register a callback for the clicked signal:

    evas_object_smart_callback_add(map, "clicked", clicked_cb, data);

void
clicked_cb(void *data, Evas_Object *obj, void *event_info)
{
    dlog_print(DLOG_INFO, LOG_TAG, "Map clicked\n");
}

The following example shows a simple use case of the map component.

Alignment

Evas_Object *win;
Evas_Object *conf;
Evas_Object *nf;
Evas_Object *box;
Evas_Object *map;

/* Starting right after the basic EFL UI layout code */
/* win - conformant - naviframe */

/* Add a box to contain a map and push the box into the naviframe */
box = elm_box_add(nf);
evas_object_show(box);
elm_naviframe_item_push(nf, "Map", NULL, NULL, box, NULL);

/* Add a map */
map = elm_map_add(box);
evas_object_size_hint_align_set(map, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_size_hint_weight_set(map, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);

/* Set zoom mode to manual and zoom level to 12 */
elm_map_zoom_mode_set(map, ELM_MAP_ZOOM_MODE_MANUAL);
elm_map_zoom_set(map, 12);

/* Show a region (2.2 N, 48.8 E) */
elm_map_region_show(map, 2.2, 48.8);

evas_object_show(map);
elm_box_pack_end(box, map);
