Detailed Documentation​

This interface represents a viewable area of the map.

Properties​

MapCenter​

LatLng MapCenter

The center of the map view's viewable area

MapRadius​

double MapRadius

The radius of the map view's viewable area, in meters

ActiveMapTiles​

IReadOnlyDictionary<ulong, IMapTile> ActiveMapTiles

All active IMapTile s in the current IMapView

AreMapTileRequestsPending​

bool AreMapTileRequestsPending

True when there are pending requests for IMapTile s.

Events​

MapTileAdded​

event MapTileAdded()

Event that's raised when a new IMapTile has been downloaded or retrieved from the local cache, decoded, and is ready for use.

MapTileRemoved​

event MapTileRemoved()

Event that's raised when an IMapTile is no longer in view.

MapViewRadiusChanged​

event MapViewRadiusChanged()

Event that's raised when the map view's radius changes.

MapViewCenterChanged​

event MapViewCenterChanged()

Event that's raised when the map view's center changes.

ZoomLevelTransitionBegin​

event ZoomLevelTransitionBegin()

Event that's raised at the beginning of the transition from one zoom level to another.

ZoomLevelTransitionEnd​

event ZoomLevelTransitionEnd()

Event that's raised when the transition from one zoom level to another is complete, and that all pending requests for IMapTile s from the new zoom level have been fulfilled.

MapTileRequestsPending​

event MapTileRequestsPending()

Event that's raised when the current IMapView has pending requests for IMapTile s.

MapTileRequestsCompleted​

event MapTileRequestsCompleted()

Event that's raised when all of the current IMapView 's pending requests for IMapTile s have been fulfilled.

Methods​

SetMapViewCenter​

void SetMapViewCenter(in LatLng latLng)

This method is called to update the IMapView 's position (in response to changes in the device's GPS, for example).

    Parameters:

    latLng - The map view's center, in lat/lng coordinates.

SetMapViewRadius​

void SetMapViewRadius(double mapRadius)

This method is called to update the map view's viewable radius (when the map is zoomed in or out, for example).

    Parameters:

    mapRadius - The map view's viewable radius, in meters.

SetViewableArea​

void SetViewableArea(in LatLng latLng, double mapRadius)

This method is called to update the IMapView 's position and viewable radius (in response to changes in the device's GPS or if the map is zoomed in or out, for example).

    Parameters:

    latLng - The map view's center, in lat/lng coordinates.

    mapRadius - The map view's viewable radius, in meters.

SetViewableArea​

void SetViewableArea(in ViewPoint viewPoint)

This method is called to update the IMapView 's position and viewable radius (in response to changes in the device's GPS or if the map is zoomed in or out, for example).

    Parameters:

    viewPoint - The view's location and viewable radius
