Map

Widget description

The Map is a widget specifically for displaying a geographic map. It uses OpenStreetMap as map tile provider, YOURS for routing calculation and Nominatim to convert geographic coordinates to/from address names. 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

• automatic grouping of markers based on zoom level

• routes calculation

• names/coordinates conversion (and viceversa)

Emitted signals

• clicked - Called when a user has clicked the map without dragging around.

• clicked,double - 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.

Scrollable Interface

This widget supports the scrollable interface.

If you wish to control the scolling behaviour using these functions, inherit both the widget class and the Scrollable class using multiple inheritance, for example:

class ScrollableGenlist(Genlist, Scrollable):
    def __init__(self, canvas, *args, **kwargs):
        Genlist.__init__(self, canvas)

Zoom until map fits inside the scroll frame with no pixels outside this area.

efl.elementary.ELM_MAP_ZOOM_MODE_AUTO_FILL

Zoom until map fills scroll, ensuring no pixels are left unfilled.

Inheritance diagram

class efl.elementary.Map(Object parent, *args, **kwargs)

Parameters

• parent (efl.evas.Object) – The parent object

• **kwargs – All the remaining keyword arguments are interpreted as properties of the instance

class efl.elementary.MapRoute(Object map, Elm_Map_Route_Type type, Elm_Map_Route_Method method, double flon, double flat, double tlon, double tlat, func, *args, **kwargs)

A route will be traced by point on coordinates to point on coordinates , using the route service set with Map.source_set().
