Dear Kyle et al,
I've solved my little problem and I'm posting the resulting code here.
I'm afraid that the code it's really kludgy, but as I've seen that this
is a common problem, I'm pasting it hoping that it will be useful to
someone.
// first we create an add the edge
ObjectHolderDirectedEdge edge = new ObjectHolderDirectedEdge(firstNode,
secondNode, anObject);
graph.addEdge(edge); // graph is a JGraphT ListenableGraph
// then we modify it's appearance
Map nested = new Hashtable();
Map attributeMap = new Hashtable();
DefaultGraphCell edgeCell = jgraphAdapter.getEdgeCell(edge); // jgraph
is, obviously a JGraph object.
//
jgraphAdapter is a JGraphModelAdapter
GraphConstants.setLineColor(attributeMap, Color.BLUE);
GraphConstants.setLineEnd(attributeMap, GraphConstants.ARROW_TECHNICAL);
GraphConstants.setEditable(attributeMap, false);
nested.put(edgeCell, attributeMap);
jgraph.getGraphLayoutCache().edit(nested, null, null, null);
hth.
best to all,
tom.
