map_inheritance_tree.png

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:

  • "default"

Enumeration Type Documentation

Set the name search method.

This is for name module interface.

Set map's zoom behavior. It can be set to manual or automatic.

Default value is ELM_MAP_ZOOM_MODE_MANUAL.

Values don't work as bitmask, only one can be chosen.

Valid sizes are 2^zoom, consequently the map may be smaller than the scroller view.

See elm_map_zoom_mode_set() See elm_map_zoom_mode_get()

)

Request a address or geographic coordinates(longitude, latitude) from a given address or geographic coordinate(longitude, latitude).

If you want to get address from geographic coordinates, set input address as null and set lon, lat as you want to convert. If address is set except NULL, lon and lat are checked.

To get the string for this address, elm_map_name_address_get should be used after callback or "name,loaded" signal is called.

To get the longitude and latitude, elm_map_region_get should be used.

Add a new class overlay to the map object. This overlay has a class type.

This overlay is not shown before overlay members are appended. if overlay members in the same class are close, group overlays are created. If they are far away, group overlays are hidden. When group overlays are shown, they have default style layouts at first.

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.

See also:
elm_map_overlay_class_zoom_max_set()
Since :
2.3.1
void elm_map_overlay_class_zoom_max_set ( Elm_Map_Overlay clas,
int  zoom 
)

Set the maximum zoom from where the overlay members in the class can be 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:
overlayThe overlay to return color.
rPointer to store the red channel value.
gPointer to store the green channel value.
bPointer to store the blue channel value.
aPointer 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:
overlayThe overlay to be set color.
rRed channel value, from 0 to 255.
gGreen channel value, from 0 to 255.
bBlue channel value, from 0 to 255.
aAlpha 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.

See also:
elm_map_overlay_color_get()

Get the content object.

Parameters:
overlayThe overlay to return the content.
Returns:
Return the evas object if it exists, else NULL.

Only default and class type overlay support this function.

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

Do not modify this object (move, show, hide, del, etc.). You can only resize this.

The content can be set by elm_map_overlay_content_set().

See also:
elm_map_overlay_content_set()
Since :
2.3.1
void elm_map_overlay_content_set ( Elm_Map_Overlay overlay,

Parameters:
overlayThe overlay to be set the content.
objThe evas object will be used to display the overlay.

Only default and class type overlay support this function.

The content should be resized or set size hints before set to the overlay. Do not modify this object (move, show, hide, del, etc.), after set. You can only resize this.

This content is what will be inside the overlay that will be displayed. If a content is set, icon and default style layout are no more used before the content is deleted.
