Blush... Currently it (the selection style) is hardcoded. How is this
for a way of handling this:
There can be an object on each map's blackboard that is the selection
style. You can get that style and modify however you desire. Another
idea is to have each layer have its own selection style but we have to
becareful there because it could go a little crazy after a while.

Hi all. I have got my own view that lists features currently displayed
on the map for a particular layer. I have got it so that when I select
a feature in the list a Filter is set on the layer with the id of the
selected feature. When that happens it displays a little orange
square/circle on the feature.
Here is the code:
public void highlightEventOnMap(String id) {
IMap map = ApplicationGIS.getActiveMap();
LayerImpl eventLayer = (LayerImpl)
getLayerByName(LAYER_ROADEVENT, map);
FilterFactory filterFactory = new FilterFactoryImpl();
CompareFilter filter = null;
try {
FeatureSource featureSource = (FeatureSource)
eventLayer.getResource(
FeatureSource.class, null);
filter =
filterFactory.createCompareFilter(CompareFilter.COMPARE_EQUALS);
FeatureType featureType =
featureSource.getFeatures().getSchema();
filter.addLeftValue(filterFactory.createAttributeExpression(featureType,
"roadeventid"));
filter.addRightValue(filterFactory.createLiteralExpression(id));
eventLayer.setFilter(filter);
} catch (Exception e) {
e.printStackTrace();
}
}
By calling ILayer.setFilter(filter) there is a small orange mark put
on the map on top of the feature graphic. Note that this happens by
default and I just discovered it by accident one day.
What I want to know is how do I change the style of that mark? Is
there a way of modifying it? I believe that there is a selection layer
or something that is probably doing this. Do I need to retrieve that
layer and apply a style to it or something similar? And if so, how do
I get hold of that layer?
Thanks in advance,
Mark
