Sorry, it should have been:
{
import com.vividsolutions.jts.geom.*;
import com.vividsolutions.jump.feature.*;
import com.vividsolutions.jump.workbench.model.*;
features=
wc.getLayerViewPanel().getSelectionManager().getFeaturesWithSelectedItems();
Iterator i = features.iterator();
if (features.size() == 2){
feature = (Feature) i.next();
geoOne = feature.getGeometry();
feature = (Feature) i.next();
geoTwo= feature.getGeometry();
htmlFrame = wc.workbench.frame.outputFrame;
htmlFrame.createNewDocument();
htmlFrame.addText("Distance = "+geoOne.distance(geoTwo));
wc.workbench.frame.flash(htmlFrame);
htmlFrame.surface();
}
}
The former script got the distance between the first two features on the
selected layer. This one uses the two selected items.
