GWT-OL

gwt-ol this wrapper for OpenLayers.

Based on GWT 2.8.0 adn JsInterop. All functional writed without JSNI, uses only JsFunction, JsContructor, JsProperty, JsMethod and other annotations of JsInterop.

This wrapper will strive for 100% implementation of the functional OpenLayers.

Java API looks like as JavaScript. What was done:

• OpenLayers API like as native JavaScript. Based on OpenLayers source code
• Simple support Callback functions.
• Full OpenLayers documentation in javadoc. You can see they on official OpenLayers or on site gwt-ol Documentation
• Examples showcase.
• Integration with gwt-olcs

Getting started

You not need include JavaScript of Cesium into main html file, injection realised in GWT code. Now no need callback for ScriptInjection or AttachOrDetach, all worked "out from box". See Showcase or basic example:

public class OSM extends AbstractExample {

    @Inject
    public OSM(ShowcaseExampleStore store) {
        super("OSM", "OpenStreetMap", new String[]{"Showcase", "OpenLayers", "OSMSource"}, store);
    }

    @Override
    public void buildPanel() {
        TileLayerOptions tileLayerOptions = new TileLayerOptions();
        tileLayerOptions.source = new OSMSource();
        TileLayer tileLayer = new TileLayer(tileLayerOptions);

        ViewOptions viewOptions = new ViewOptions();
        viewOptions.center = new Coordinate(new double[] {-10997148, 4569099});
        viewOptions.zoom = 4;

        MapOptions mapOptions = new MapOptions();
        mapOptions.logoVisible = false;
        mapOptions.loadTilesWhileAnimating = true;
        mapOptions.loadTilesWhileInteracting = true;
        mapOptions.layers = new Collection<>();
        mapOptions.layers.push(tileLayer);
        mapOptions.view = new View(viewOptions);

        MapPanel mapPanel = new MapPanel(mapOptions);
        mapPanel.setHeight("400px");

        contentPanel.add(new HTML("<p>Use Viewer to start building new applications or easily embed Cesium into existing applications.</p>"));
        contentPanel.add(mapPanel);

        initWidget(contentPanel);
    }

    @Override
    public String[] getSourceCodeURLs() {
        String[] sourceCodeURLs = new String[1];
        sourceCodeURLs[0] = GWT.getModuleBaseURL() + "examples/" + "HelloWorld.txt";
        return sourceCodeURLs;
    }
}

Build library and examples:

== You need Java 8 for build examples.

• mvn -U clean install
