Sure I can!
This is the wrapper class:
import com.google.gwt.core.client.JavaScriptObject;
import com.google.gwt.core.client.JsArray;
import com.google.gwt.dom.client.Element;
import com.google.gwt.visualization.client.AbstractDataTable;
import
com.google.gwt.visualization.client.visualizations.corechart.CoreChart;
import com.google.gwt.visualization.client.visualizations.corechart.Options;
import com.google.gwt.visualization.client.visualizations.corechart.Series;
public class GeoChart extends CoreChart
{
public static class GeoOptions extends Options
{
public static GeoOptions create()
{
return JavaScriptObject.createObject().cast();
}
protected GeoOptions()
{
}
public final native void setSeries(int index, Series seriesAtIndex) /*-{
if (!this.series) {
this.series = {};
}
this.series[index] = seriesAtIndex;
}-*/;
public final native void setSeries(JsArray<Series> series) /*-{
this.series = series;
}-*/;
public final void setSeriesType(Series.Type seriesType)
{
setSeriesType(seriesType.name().toLowerCase());
}
public final native void setSeriesType(String seriesType) /*-{
this.seriesType = seriesType;
}-*/;
}
public GeoChart(AbstractDataTable data, Options options)
{
super(data, options);
}
/**
* @see GeoChart#createJso(Element)
*/
@Override
protected native JavaScriptObject createJso(Element parent) /*-{
return new $wnd.google.visualization.GeoChart(parent);
}-*/;
}
And bellow is the call to this class from my code:
final Options op = createOptions();
op.set("region", "IT");
op.set("displayMode", "markers");
Runnable onLoadCallback = new Runnable()
{
public void run()
{
GeoChart geoChartMarkers = new GeoChart(createTable(), op);
widgetEditorChartPreviewPanel.clear();
widgetEditorChartPreviewPanel.add(geoChartMarkers, "chartPreview");
}
};
VisualizationUtils.loadVisualizationApi(onLoadCallback, GeoChart.PACKAGE);
Thanks!
