I know that there is a difference between the two styles. I am applying
my own style to my layer to get external graphics on the map, and I need
the style of the selection 'thing' to change so that it doesn't blob my
icons but rather highlight/emphasize them in some way.
I'm not convinced about multiple selection styles at this stage either
because I don't need it. But I can see that if I had different report
views for different feature types/layers I may want to emphasize the
selected feature differently depending on the main style for that layer.
Thanks Jesse

There is a difference between style and selection style though. Are
you sure you want be able to have a different selection style for each
layer? You haven't convinced me yet but I'm not completely adverse to
the idea... I'll think about it a bit for now.
The hardcoded style can be found in
SelectionStyleContent.createDefaultStyle(layer);

I think that each layer should probably have it's own selection style
so that you can highlight different feature types in different ways
depending on the type and the way they are rendered.
For example, on my layer I am using external graphics for each point
feature. Putting a blob on top of the icon isn't really what I
need... I'd like to be able to highlight the edge of the icon in some
way (which I still have to play with). Whereas another layer might
have a circle for points, or another a square which you could simply
render another circle/square of a different color over top of the
original.
In the meantime, where can I find that hardcoded style that you are
referring to so that I can attack it and modify it for my needs in
the meantime?
Thanks,
Mark

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
