This is a widget specifically for displaying a map. It uses basically OpenStreetMap provider http://www.openstreetmap.org/ but custom providers can be added.

It supports some basic but yet nice features:

zooming and scrolling,
markers with content to be displayed when user clicks over them,
group of markers and
routes.

This widget implements the elm-scrollable-interface interface, so that all (non-deprecated) functions for the base Scroller widget also work for map objects.

Smart callbacks one can listen for:

"clicked" - This is called when a user has clicked the map without dragging around.
"clicked,double" - This is called when a user has double-clicked the map.
"press" - This is called when a user has pressed down on the map.
"longpressed" - This is called when a user has pressed down on the map for a long time without dragging around.
"scroll" - the content has been scrolled (moved).
"scroll,drag,start" - dragging the contents around has started.
"scroll,drag,stop" - dragging the contents around has stopped.
"scroll,anim,start" - scrolling animation has started.
"scroll,anim,stop" - scrolling animation has stopped.
"zoom,start" - Zoom animation started.
"zoom,stop" - Zoom animation stopped.
"zoom,change" - Zoom changed when using an auto zoom mode.
"tile,load" - A map tile image load begins.
"tile,loaded" - A map tile image load ends.
"tile,loaded,fail" - A map tile image load fails.
"route,load" - Route request begins.
"route,loaded" - Route request ends.
"route,loaded,fail" - Route request fails.
"name,load" - Name request begins.
"name,loaded" - Name request ends.
"name,loaded,fail" - Name request fails.
"overlay,clicked" - A overlay is clicked.
"loaded" - when a map is finally loaded. (since 1.7)
"language,changed" - the program's language changed
"focused" - When the map has received focus. (since 1.8)
"unfocused" - When the map has lost focus. (since 1.8)

Available style for map widget:

"default"

Available style for markers:

"radio"
"radio2"
"empty"

Available style for marker bubble:

	)

Set the object color of the overlay.

Parameters:

overlay	The overlay to be set color.

g	Green channel value, from 0 to 255.
b	Blue channel value, from 0 to 255.
a	Alpha channel value, from 0 to 255.

It uses an additive color model, so each color channel represents how much of each primary colors must to be used. 0 represents absence of this color, so if all of the three are set to 0, the color will be black.

These component values should be integers in the range 0 to 255, (single 8-bit byte).

This sets the color used for the overlay. By default, it is set to solid red (r = 255, g = 0, b = 0, a = 255).

For alpha channel, 0 represents completely transparent, and 255, opaque.

Get a value whether the overlay is visible or not.

Parameters:

overlay The overlay to return visible state.

Returns:: EINA_TRUE means overlay is visible. EINA_FALSE indicates it is not.

The visible of the overlay can not be set. This value can be changed dynamically while zooming and panning

void elm_map_overlays_show ( Eina_List * overlays )

Move and zoom the map to display a list of overlays.

Parameters:

overlays A list of Elm_Map_Overlay handles.

The map will be centered on the center point of the overlays in the list. Then the map will be zoomed in order to fit the overlays using the maximum zoom which allows display of all the overlays.

Warning:: All the overlays should belong to the same map object.

See also:: elm_map_overlay_show() to show a single overlay.

Examples:: map_example_02.c.

void elm_map_route_del ( Elm_Map_Route * route )

Remove a route from the map.

Parameters:

route The route to remove.

See also:: elm_map_route_add()

Since :: 2.3

Examples:: map_example_03.c.

double elm_map_route_distance_get ( const Elm_Map_Route * route )

Get the route distance in kilometers.

Parameters:

route The route object.

Returns:: The distance of route (unit : km).

Since :: 2.3

const char* elm_map_route_node_get ( const Elm_Map_Route * route )

Get the information of route nodes.

Parameters:

route The route object.

Returns:: Returns a string with the nodes of route.

Since :: 2.3

const char* elm_map_route_waypoint_get ( const Elm_Map_Route * route )

Get the information of route waypoint.

Parameters:

route the route object.

Returns:: Returns a string with information about waypoint of route.

Since :: 2.3

Eina_Bool elm_map_wheel_disabled_get ( const Evas_Object * obj )

Get a value whether mouse wheel is enabled or not.

Mouse wheel can be used for the user to zoom in or zoom out the map.

Parameters:

[in] obj The object.

Returns:: Use true to disable mouse wheel or false to enable it.

Since :: 2.3

void elm_map_wheel_disabled_set	(	Evas_Object *	obj,
		Eina_Bool	disabled
	)

Enable or disable mouse wheel to be used to zoom in / out the map.

Wheel is enabled by default.

Parameters:

[in]	obj	The object.
[in]	disabled	Use `true` to disable mouse wheel or `false` to enable it.

Since :: 2.3

int elm_map_zoom_get ( const Evas_Object * obj )

Get the zoom level of the map.

This returns the current zoom level of the map object.

Note that if you set the fill mode to other than ELM_MAP_ZOOM_MODE_MANUAL (which is the default), the zoom level may be changed at any time by the map object itself to account for map size and map viewport size.

Parameters:

[in] obj The object.

Returns:: The zoom level.

Since :: 2.3

Examples:: map_example_01.c, map_example_02.c, and map_example_03.c.

Elm_Map_Zoom_Mode elm_map_zoom_mode_get ( const Evas_Object * obj )

Get the zoom mode used by the map object.

This function returns the current zoom mode used by the ma object.

Parameters:

[in] obj The object.

Returns:: The zoom mode of the map, being it one of ELM_MAP_ZOOM_MODE_MANUAL (default), ELM_MAP_ZOOM_MODE_AUTO_FIT, or ELM_MAP_ZOOM_MODE_AUTO_FILL.

Since :: 2.3

void elm_map_zoom_mode_set	(	Evas_Object *	obj,
		Elm_Map_Zoom_Mode	mode
	)

Set the zoom mode used by the map object.

This sets the zoom mode to manual or one of the automatic levels. Manual (ELM_MAP_ZOOM_MODE_MANUAL) means that zoom is set manually by elm_map_zoom_mode_set and will stay at that level until changed by code or until zoom mode is changed. This is the default mode.

The Automatic modes will allow the map object to automatically adjust zoom mode based on properties. ELM_MAP_ZOOM_MODE_AUTO_FIT will adjust zoom so the map fits inside the scroll frame with no pixels outside this area. ELM_MAP_ZOOM_MODE_AUTO_FILL will be similar but ensure no pixels within the frame are left unfilled. Do not forget that the valid sizes are 2^zoom, consequently the map may be smaller than the scroller view.

Parameters:

[in]	obj	The object.
[in]	mode	The zoom mode of the map, being it one of ELM_MAP_ZOOM_MODE_MANUAL (default), ELM_MAP_ZOOM_MODE_AUTO_FIT, or ELM_MAP_ZOOM_MODE_AUTO_FILL.

Since :: 2.3

Examples:: map_example_01.c, map_example_02.c, and map_example_03.c.

void elm_map_zoom_set	(	Evas_Object *	obj,
		int	zoom
	)

Set the zoom level of the map.

This sets the zoom level.

It will respect limits defined by elm_map_zoom_min_set and elm_map_zoom_max_set.

By default these values are 0 (world map) and 18 (maximum zoom).

This function should be used when zoom mode is set to ELM_MAP_ZOOM_MODE_MANUAL. This is the default mode, and can be set with elm_map_zoom_mode_set.

Parameters:

[in]	obj	The object.
[in]	zoom	The zoom level.

Since :: 2.3

Examples:: map_example_01.c, map_example_02.c, and map_example_03.c.
