Hi:
Here is the solution I used
https://github.com/guziy/GeotoolsDemo/blob/master/src/RoughCreatingPoint.java
It creates a maplayer event, where the changed layer is specified and then
fires it using MapPane method layerChanged()...
Still I find it too much reloading a whole layer for just one point, we
should think of a better solution mayb another event object where the
region changed could be specified....
void createFeatures(MapMouseEvent ev) {
double[] xy = ev.getWorldPos().getCoordinate();
Point point = geometryFactory.createPoint(new Coordinate(xy[0], xy[1]));
pointCollection.add(SimpleFeatureBuilder.build(pointType, new
Object[]{point}, null));
//create map layer event
MapLayerEvent mple = new MapLayerEvent(pointLayer,
MapLayerEvent.DATA_CHANGED);
//create maplayer list event
MapLayerListEvent mplle = new MapLayerListEvent(map,
pointLayer, map.layers().indexOf(pointLayer), mple);
mapFrame.getMapPane().layerChanged(mplle);
System.out.println(MessageFormat.format("Created Point: {0}", point));
}
Cheers
