All Implemented Interfaces:

public final class Geomap
extends MapWidget
implements Scene

A GWT widget wrapping an OpenLayers geographic map and its views. Apparently OpenLayers does not allow for separate views of the same map to be placed here and there; all must be stacked (layered) together under a single DOM object. This is the widget that wraps that DOM object. It uses geoscoping, q.v. for the format of the 's' scoping switch.

Constructor Detail

Geomap

public Geomap(Spool _spool)

Constructs a Geomap.

Parameters:

_spool - the spool for the release of associated holds. When unwound it releases the holds of the geomap and thereby disables it.

Method Detail

forceInitClass

public static void forceInitClass()

Does nothing itself but the call forces static initialization of this class.

getDefaultBaseLayerName

@GWTConfigCallback
public static String getDefaultBaseLayerName()

The default base layer for the geomap. The layer is specified by its name in the layer switcher. The state of the switcher is persisted through a cookie, so this value is only a default. If no value is set, then "Google Satellite" is used.

See Also:

setDefaultBaseLayerName(String)

setDefaultBaseLayerName

@GWTConfigCallback
public static void setDefaultBaseLayerName(String s)

Sets the default base layer for the geomap. Call this method from the global configuration function voGWTConfig.s_gwt_scene in this manner:

   s_gwt_scene_geo_Geomap_setDefaultBaseLayerName( 'Osmarender OSM' );
     // otherwise 'Google Satellite'

Throws:

NullPointerException - if s is null.

getDefaultBaseLayerName()

transformFromEPSG4326

void transformFromEPSG4326(Point point)

Transforms from latitude/longitude coordinates (EPSG:4326) to the projection of this geomap, which is spherical mercator (EPSG:900913).

inScope

public boolean inScope(BiteJS bite)

Description copied from interface: Scene

Tests whether the specified bite is within the current scope of this scene.

Specified by:

inScope in interface Scene
