create a new Map Widget

Parameters:

options - MapOptions

Method Detail

newInstance

public static MapWidget newInstance(MapImpl impl)

Reconstruct the mapWidget from JSO

Parameters:

impl -

Returns:

NULL if input is NULL

onDetach

protected void onDetach()

Overrides:

onDetach in class Widget

getJso

public MapImpl getJso()

get JavaScriptObject instance.

Returns:

MapImpl

setJso

public void setJso(MapImpl impl)

sets JavaScriptObject instance.

Parameters:

impl - MapImpl

fitBounds

public void fitBounds(LatLngBounds bounds)

Sets the viewport to contain the given bounds.

Parameters:

bounds - LatLngBounds

getBounds

public LatLngBounds getBounds()

Returns the lat/lng bounds of the current viewport. If the map is not yet initialized (i.e. the mapType is still null), or center and zoom have not been set then the result is null or undefined.

Returns:

LatLngBounds

getCenter

public LatLng getCenter()

get Center

Returns:

LatLng

getDiv

public Element getDiv()

get Element

getHeading

public int getHeading()

Returns the compass heading of aerial imagery. The heading value is measured in degrees (clockwise) from cardinal direction North.

Returns:

int

getMapTypeId

public final MapTypeId getMapTypeId()

gets MapTypeId

Returns:

MapTypeId

getProjection

public Projection getProjection()

Returns the current Projection. If the map is not yet initialized (i.e. the mapType is still null) then the result is null. Listen to projection_changed and check its value to ensure it is not null.

Returns:

Projection

getStreetView

public StreetViewPanoramaImpl getStreetView()

Returns the default StreetViewPanorama bound to the map, which may be a default panorama embedded within the map, or the panorama set using setStreetView(). Changes to the map's streetViewControl will be reflected in the display of such a bound panorama.

Returns:

StreetViewPanoramaImpl

getTilt

public int getTilt()

gets Returns the angle of incidence for aerial imagery (available for SATELLITE and HYBRID map types) measured in degrees from the viewport plane to the map plane. A value of 0 indicates no angle of incidence (no tilt) while 45° imagery will return a value of 45.

getZoom

public int getZoom()

get zoom

panBy

public void panBy(int x,
         int y)

Changes the center of the map by the given distance in pixels. If the distance is less than both the width and height of the map, the transition will be smoothly animated. Note that the map coordinate system increases from west to east (for x values) and north to south (for y values).

Parameters:

x -

y -

panTo

public void panTo(LatLng latLng)

Changes the center of the map to the given LatLng. If the change is less than both the width and height of the map, the transition will be smoothly animated.

Parameters:

latLng -

panToBounds

public void panToBounds(LatLngBounds latLngBounds)

Pans the map by the minimum amount necessary to contain the given LatLngBounds. It makes no guarantee where on the map the bounds will be, except that as much of the bounds as possible will be visible. The bounds will be positioned inside the area bounded by the map type and navigation (pan, zoom, and Street View) controls, if they are present on the map. If the bounds is larger than the map, the map will be shifted to include the northwest corner of the bounds. If the change in the map's position is less than both the width and height of the map, the transition will be smoothly animated.

Parameters:

latLngBounds -

setCenter

public void setCenter(LatLng latlng)

set center

Parameters:

latlng -
