Sincerely,

I want to use this library.

I have lattitude and longitude with me and i need to show the location on the map.

Also, need to find the nearest locations based on lattitue/longitude.

I went through the docs but could not understand the right class to be used.

Can you give me some sample code ?

Thanks

Deepak

I'm using the GWT Maps V3 Api from https://github.com/branflake2267/GWT-Maps-V3-Api

After finding directions on the map, I'm trying to clear the previous ones before finding new.

In DirectionsRenderer:

  /**
   * This method specifies the map on which directions will be rendered. Pass null to remove the directions from the map.
   * @param mapWidget
   */
  public final void setMap(MapWidget mapWidget) {
    setMapImpl(mapWidget.getJso());
  }

  private final native void setMapImpl(MapImpl map) /*-{
    this.setMap(map);
  }-*/;

I'm trying to pass:

directionsDisplay.setMap(null);

which results in NPE:

Caused by: java.lang.NullPointerException: null
    at com.google.gwt.maps.client.services.DirectionsRenderer$.setMap$(DirectionsRenderer.java:50)

Anyone used this API and knows how to clear directions from the map widget?

As far as, I know there has to be a unique for using google maps.

Where would i place my unique key?

I have a limited requirement to find near about places using LatLong, will it be enough to use just Basic map widget class?

Hi Deepak,

Here is a show case of different features from the library: http://gonevertical-apis.appspot.com/
You can find the source code here: https://github.com/branflake2267/GWT-Maps-V3-Api/tree/master/Apis_Maps_Test/src/com/google/gwt/maps/testing/client/maps

Regarding clearing the directions, Brandon has already fixed it.

This is the V3 Maps API. The V3 does not use API keys like V2 does. Because you download the JS from Google, and it has to start on your site (where it can detect the URL), they track the API usage that way.

So, you should be able to just use the example in the Showcase (2nd example) to fetch your directions

Sincerely,

Joseph

This should be resolved, but if it isn't let me know. :)

Are you looking for the PlaceServiceSearchRequest? If so, I added and example map in the live demo maps.

I added jar file APIs_Google_map3.8.0beta.jar to my classpath.

Added this to lib also.

Included 

<inherits name='com.google.gwt.maps.Apis_Google_Maps' /> to my *.gwt.xml

When i run the app in local, i get the following exception

Unable to find 'com/google/gwt/ajaxloader/AjaxLoader.gwt.xml' on your classpath;

Thanks

Now, I added gwt-ajaxloader.jar

It was able to run in dev mode.

Now i run the following code

MapOptions mo = MapOptions.newInstance();

LatLng ll = LatLng.newInstance(Double.parseDouble(latitude), Double.parseDouble(longitude));

mo.setCenter(ll);

mo.setZoom(4);

mo.setMapTypeId(MapTypeId.HYBRID);

MapWidget mw = new MapWidget(mo);

// enquiryDiv.appendChild(mw.getElement());

com.google.gwt.core.client.JavaScriptException: (TypeError) @com.google.gwt.core.client.impl.Impl::apply(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)([JavaScript object(6222), JavaScript object(6221), JavaScript object(6296)]): $wnd.google is undefined

Could not resolve the exception mentioned.

Then i copied PlaceSearchMapWidget.java and tried to use.

But could not create the widget as 

    PlacesService placeService = PlacesService.newInstance(attrContainer, mapWidget);

And i could not understand 'attrContainer' parameter.

My requirement is simple,

I have latitude and longitude. I need to search places within 2 kms area of this latlong.

Pls let me know which kind of class will be useful for me ?

Regards

Deepak

The api will need to be loaded like so:

private void loadMapApi() {
    boolean sensor = true;


    // load all the libs for use in the maps

    ArrayList<LoadLibrary> loadLibraries = new ArrayList<LoadApi.LoadLibrary>();
    loadLibraries.add(LoadLibrary.ADSENSE);
    loadLibraries.add(LoadLibrary.DRAWING);
    loadLibraries.add(LoadLibrary.GEOMETRY);
    loadLibraries.add(LoadLibrary.PANORAMIO);
    loadLibraries.add(LoadLibrary.PLACES);
    loadLibraries.add(LoadLibrary.WEATHER);
    loadLibraries.add(LoadLibrary.VISUALIZATION);


    Runnable onLoad = new Runnable() {
      @Override
      public void run() {
        draw();
      }
    };


    LoadApi.go(onLoad, loadLibraries, sensor);
  }
