Hi All,
The following code which uses CompoundDirectedGraphLayout produces the
layout captured in the attached Compound.png. As you can see one of the
Edges inappropriately shoots out to the side.
This equivalent graph when laid out using DirectedGraphLayout does not have
this problem (e.g., see the attached "Not Compound.png" and the code that
produced it included below).
Am I doing anything wrong here? I'm using 3.2M5a.
Thanks for any help,
Rick
------------------------------------------------------
NodeList nodes = new NodeList();
EdgeList edges = new EdgeList();
Subgraph p = new Subgraph("parent");
nodes.add(p);
Node a = new Node("a", p);
nodes.add(a);
Node b = new Node("b", p);
nodes.add(b);
Node c = new Node("c", p);
nodes.add(c);
Node d = new Node("d", p);
nodes.add(d);
Node e = new Node("e", p);
nodes.add(e);
edges.add(new Edge(a, d));
edges.add(new Edge(a, c));
edges.add(new Edge(b, c));
edges.add(new Edge(b, d));
edges.add(new Edge(b, e));
edges.add(new Edge(c, d));
edges.add(new Edge(c, e));
CompoundDirectedGraph graph = new CompoundDirectedGraph();
graph.nodes = nodes;
graph.edges = edges;
new CompoundDirectedGraphLayout().visit(graph);
------------------------------------------------------------ ---
non-compound version:
NodeList nodes = new NodeList();
EdgeList edges = new EdgeList();
Node a = new Node("a");
nodes.add(a);
Node b = new Node("b");
nodes.add(b);
Node c = new Node("c");
nodes.add(c);
Node d = new Node("d");
nodes.add(d);
Node e = new Node("e");
nodes.add(e);
edges.add(new Edge(a, d));
edges.add(new Edge(a, c));
edges.add(new Edge(b, c));
edges.add(new Edge(b, d));
edges.add(new Edge(b, e));
edges.add(new Edge(c, d));
edges.add(new Edge(c, e));
DirectedGraph graph = new DirectedGraph();
graph.nodes = nodes;
graph.edges = edges;
new DirectedGraphLayout().visit(graph);

Please test using the latest release candidate, then open a bugzilla if it
is still reproducible.
