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 to:

"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)

See also:: elm_map_name_add()

Since :: 2.3.1

void elm_map_name_del ( Elm_Map_Name * name )

You can change the state (hidden, paused, etc.) or set the content or icon of the group overlays by chaning the state of the class overlay. Do not modify the group overlay itself.

Also these changes have a influence on the overlays in the same class even if each overlay is alone and is not grouped.

void elm_map_overlay_color_get	(	const Elm_Map_Overlay *	overlay,
		int *	r,
		int *	g,
		int *	b,
		int *	a
	)

Get the object color of the overlay.

Parameters:

overlay	The overlay to return color.
r	Pointer to store the red channel value.
g	Pointer to store the green channel value.
b	Pointer to store the blue channel value.
a	Pointer to store the alpha channel value.

See also:: elm_map_overlay_color_set()

Since :: 2.3.1

void elm_map_overlay_color_set	(	Elm_Map_Overlay *	overlay,
		int	r,
		int	g,
		int	b,
		int	a
	)

Set the object color of the overlay.

Parameters:

overlay	The overlay to be set color.
r	Red channel value, from 0 to 255.
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.

Function supports only ELM_MAP_OVERLAY_TYPE_CLASS, ELM_MAP_OVERLAY_TYPE_DEFAULT and ELM_MAP_OVERLAY_TYPE_ROUTE Elm_Map_Overlay_Type types.

Returned content is what being inside the overlay that being displayed.
