Constructor Detail

This method displays a geographical map, allowing multiple containers and objects to be added to it.

new nokia.maps.map.Display(container, props)
Parameters:
{DOMElement} container The DOM node where the map should be established
{nokia.maps.map.Display.Properties} props The initial values of the specified properties
Events
mapviewchange(event)
This event is fired each time after the map has been rendered in response to a change the map view (see nokia.maps.map.Display.MapViewChangeEvent).

The data property of the event object provides information of all changes (see: nokia.maps.map.Display.MapViewChangeEvent#data).

IMPORTANT: Many mapviewchangeupdate events can be fired within a second, therefore you should avoid expensive operations within mapviewchangeupdate listeners.

Parameters:
{nokia.maps.map.Display.MapViewChangeEvent} event
mapviewchangeend(event)
This event is fired when the map display has been rendered to process all map view changes (see nokia.maps.map.Display.MapViewChangeEvent). At this point, you can safely execute more expensive operations to respond to a map view change (for example UI updates).
Parameters:
{nokia.maps.map.Display.MapViewChangeEvent} event
mapviewchangestart(event)
This event is fired immediately after the map view has been changed (see nokia.maps.map.Display.MapViewChangeEvent). However, it is fired only for the first change of the map view after a rendering of the map display has been finished.
Parameters:
{nokia.maps.map.Display.MapViewChangeEvent} event
resize(event)
This event is fired each time a change of the display's size is detected. It will fire multiple times during a continuos resize operation (e.g. if the display is being resized due to user input).

Note, that resizing a map will also trigger mapviewchange events.

Parameters:
{nokia.maps.dom.Event} event
resizeend(event)
This event is fired when a resizing operation has been finished (i.e. when no more changes of the display's size are detected for a certain time).

Note, that resizing a map will also trigger mapviewchange events.

Parameters:
{nokia.maps.dom.Event} event
resizestart(event)
This event is fired immediately after the size of the display has been changed. However, it is fired for the initial change of a single resize process until a resizeend has beend fired.

Note, that resizing a map will also trigger mapviewchange events.

Parameters:
{nokia.maps.dom.Event} event
Method Detail
addComponent (component) : nokia.maps.map.component.Component
The method adds a new component to the given Display instance. If a component with the same id already exists (has been added previously), the method returns that component after incrementing its reference counter (the method does not create/add multiple instances of the same component).
Examples:
var component = display.addComponent(new nokia.maps.map.component.zoom.DoubleClick());
Parameters:
{nokia.maps.map.component.Component} component A reference to the component to be added
Returns:
{nokia.maps.map.component.Component} A reference to the newly added component or to the existing component with the same identifier
destroy ()
This method destroys the map Display instance and frees the resources. The method may take up to a minute to complete, but afterwards, all of Display's properties are set to null and its methods are bound to an empty function.
geoToPixel (coord) : nokia.maps.util.Point
This method translates the received point object containing WGS84 coordinates into pixel coordinates relative to the top left corner of the map view. The coordinates of the top left corner of the map are (0,0).

This type indicates a public transport map; is using the smart map color scheme with additional public transport route lines on top. Availability of public transport information may vary.
nokia.maps.map.Provider TERRAIN
This type indicates a topographical map, where shading and color convey the shape of the terrain.
nokia.maps.map.Provider TRAFFIC
This type indicates a traffic info map; is using the smart map color scheme with additional traffic coloring for major streets and highways on top. Availability of traffic information may vary.
nokia.maps.util.OList animation
This property specifies the currently supported map animation types.

Animations depend on the platform and the rendering engine used, therefore this property must be checked at run-time to see if a specific animation is supported by the current rendering engine on the current platform.

Please note: Animation support in p2d-dom is not available at present. It will be introduced for certain environments in future releases.

In all cases, the following values for this property are supported:

  • "none" - no animation
  • "default" - default animation

Note 1: The default animation may be set to "none", which means that the rendering engine on the current platform does not support animation.

Note 2: If you specify an incorrect animation name, the animation type automatically reverts to "default".

nokia.maps.util.OList availableBaseMapTypes
A list of all available nokia.maps.map.Providers for base map types.
nokia.maps.util.OList availableOverlays
A list of all available nokia.maps.map.Providers for map overlays.
nokia.maps.util.OList components
The list of all components that have been added to the map (to the given instance of nokia.maps.map.Display).
String copyrightAlignment
This property specifies the position of the copyright information relative to the display. The allowed values are:
  • topleft
  • topcenter
  • topright
  • middleleft
  • middlecenter
  • middleright
  • bottomleft
  • bottomcenter
  • bottomright
Default Value:
"bottomleft"
Number copyrightHeight
The height in pixels of the frame containing the text "Copyright by ...".
Number copyrightWidth
The width in pixels of the frame containing the text "Copyright by ...".
Number height
The height of the map area in pixels.
Number maxHeading
The maximum supported map heading (bearing). You can obtain the maximum supported heading by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("maxHeading") obtains the current value of maxHeading.
Number maxTilt
The maximum supported map tilt. You can obtain the maximum supported tilt by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("maxTilt") obtains the current value of maxTilt.
Number maxZoomLevel
The maximum zoom level supported by the map (considering the current heading/tilting). You can obtain the maximum supported zoom level by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("maxZoomLevel") obtains the current value of maxZoomLevel.
Number minHeading
The minimum supported map heading (bearing). You can obtain the minimum supported heading by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("minHeading") obtains the current value of minHeading.
Number minTilt
The minimum supported map tilt. You can obtain the minimum supported tilt by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("minTilt") obtains the current value of minTilt.
Number minZoomLevel
The minimum zoom level supported by the map (considering the current heading/tilting). You can obtain the minimum supported zoom level by invoking the method get() on an instance of Display, with the name of this property as the only argument. For example, if "myMap" is an instance of map.Display, then the code myMap.get("minZoomLevel") obtains the current value of minZoomLevel.
nokia.maps.util.OList overlays
The list of all map overlays which are currently active for the map.
nokia.maps.util.IBox padding
This property defines the padding in pixels for each side of the map display, thus setting a virtual viewport. The virtual viewport does not affect the placing or the size of the visible map in the DOM node, but defines an area which excludes strips along the edges of the map that contain the UI elements zoom bar, copyright and map-type selector (if these elements are displayed). The virtual viewport is taken into consideration when setting the map center, when obtaining the map view bounds and when zooming to a bounding box. Its other purpose is to help prevent objects from overlapping very close to the edges of the visible map.

The map viewport determined by padding is taken into account when setting the following properties and by the following methods:

This property cannot be changed directly. Use the methods nokia.maps.map.Display#setPadding or the inherited nokia.maps.util.OObject#set instead. For example, you can call the method set() as follows: 

set("padding", aPadding);
Number poweredByHeight
The height in pixels of the frame containing the logo "Powered by ...".
Number poweredByWidth
The width in pixels of the frame containing the logo "Powered by ...".
Number width
The width of the map area in pixels.
