Hi John,
Have a look at the ModifyFeature control.
>From ModifyFeatureImpl:
public static native JSObject
createOnModificationStartCallback(OnModificationStartListener
listener)/*-{
var callback = function(obj){
var vectorFeatureObj =
@org.gwtopenmaps.openlayers.client.feature.VectorFeature::narrowToVectorFeature(Lorg/gwtopenmaps/openlayers/client/util/JSObject;)(obj);
lis...@or....OnModificationStartListener::onModificationStart(Lorg/gwtopenmaps/openlayers/client/feature/VectorFeature;)(vectorFeatureObj);
}
return callback;
}-*/;
>From ModifyFeatureOptions:
public void onModificationStart(OnModificationStartListener listener) {
JSObject callback =
ModifyFeatureImpl.createOnModificationStartCallback(listener);
getJSObject().setProperty("onModificationStart", callback);
}
>From ModifyFeature:
public interface OnModificationStartListener {
void onModificationStart(VectorFeature vectorFeature);
}
Greetings,
Edwin
