Hi,
I am currently trying to add/delete features on a feature layer and display
them on a JMapFrame. It works fine, but the MapPane doesn't repaint on
adding new features to the collection. I've read on this forum (1) that
there should be a chain of events from the FeatureCollection to the MapPane,
but it doesn't work for me, even the manual call of
frame.getMapPane.repaint() doesn't help.
Heres how i do it:
*//1. Create a JMapFrame*
MapContent map = new MapContent();
JMapFrame frame = new JMapFrame(map);
*//2. Create a SimpleFeatureList and a SimpleFeatureCollection*
List<SimpleFeature> listSF = new ArrayList<SimpleFeature>();
listSF.add(someFeatures);
ListFeatureCollection colPoints = new
ListFeatureCollection(myhelper.getFeatureTypePoint, listSF);
Layer layer = new FeatureLayer(colPoints, SLD.createPointStyle("Circle",
SLD.createPointStyle(...));
map.addLayer(messlayer);
*// 3. Now i add some more Points to the collection*
colPoints.add(someFeatures);
frame.getMapPane.repaint();
*4. ..and nothing happens. *
There's two ways how i could make the new points visible, but none of them
seems to be a good idea:
1. Remove the layer from the Pane and add ist again (map.addLayer(layer)).
2. Enable the layertable of JMapFrame and click the toggle visibility button
two times.
Can anyone please help me and show me the fault in my code/strategy? Is the
a better (and faster?) way to display dynamic features in geotools?
Best regards,
Florian
