Hello,
i try to do the following:
//create FeatureType
CoordinateReferenceSystem crs = CRS.decode("EPSG:4326");
AttributeType point =
AttributeTypeFactory.newAttributeType("Location",Point.class,true,
null,null,crs );
AttributeType name = AttributeTypeFactory.newAttributeType("Name",
String.class, false, null, "Station", null);
FeatureType stationFeatureType =
FeatureTypeBuilder.newFeatureType(new
AttributeType[] { point, name }, "StationFeatureType");
//create IGeoResource
IGeoResource stationGeoResource =
CatalogPlugin
.getDefault
().getLocalCatalog().createTemporaryResource(stationFeatureType);
//create list of IGeoResource
List <IGeoResource> geoResourceList = new LinkedList<IGeoResource>();
geoResourceList.add(stationGeoResource);
//create new map
ApplicationGIS.createAndOpenMap(geoResourceList, null, true);
//get the new layer
ILayer stationLayer = null;
List <ILayer> layerList = network.getEditorMap().getMapLayers();
for (ILayer layer: layerList) {
if (layer.getName().compareTo("StationFeatureType") == 0)
stationLayer = layer;
}
//get FeatureSource
FeatureSource stationFeatureSource =
stationLayer.getResource(FeatureSource.class, null);
//get FeatureCollection
FeatureCollection features = stationFeatureSource.getFeatures();
//AFTER all this i create i view wich displays a FeatureTableControl
FeatureTableControl ftc = new FeatureTableControl(parent, features);
All seams fine, but i notices a few problems:
1) the automatic created column header for the AttributeType point is
"GEOMETRY". but i defined it as "Location". The first thing is a
nullPointerException if the FeatureTableControl wants to display a
feature.
When i change the name of my attributetype to "GEOMETRY" all is
fine. But i
think this is a bug.
2) if i add features to the layer, no updates in the table will be
displayed. and i do not realy know which listener i should take. i
tried the
following:
every implementation of the changed method makes a tfc.update.
map.getEditManager().addListener(view_i_created);
--> all updates are seen, but if i make i commit of the station
layer i get
a "invalid thread access exception"
stationFeatureSource.addFeatureListener(view_i_created);
--> all updates are listed in the table, but the commit of the
station
layer makes no update. so all the FID are still "new*" and not the
real one
features.addListener(view_i_created);
--> nothing happens. no CollectionEvent fired
i looked in the FeatureTableControl implementation and i think this
implementation uses the CollectionListener interface too. but when no
CollectionEvents are fired, no updates are displayed.
i hope someone can help me with my 2 problem. perhaps this are bugs
or do i
missunderstand the api?
thanks forward
Ingmar
