I'm making Decision Tree, and I want to draw it using Tree. My idea is to make it like simulation. When user clicks Next, it will show him next node, and so on. So basically, I need to unhide nodes interactively (they will be hidden by default).
private Forest<TreeNode, TreeLink> g;
g = new SparseTree<TreeNode, TreeLink()>;
Than, I'm adding Vertex - root and Edges:
g.addVertex(root);
TreeLink v = new TreeLink(50, 75);
g.addEdge(v, node.parent, node, EdgeType.DIRECTED);
I made TreeNodePredicate and TreeLinkPredicate, and inserted logic for hiding/unhiding Nodes/Links. If I say
v.setVisible(false);
everything will work fine, and edge/edges will be hidden. But if I say
node.setVisible(false);
Noting happens. My tree will be displayed with all nodes unhidden - Edges will be hidden.
I'm guessing that this is not the right way to hide Nodes. I know that some JUNG classes have addChild() method (there is no addChild() here) - maybe, the key is to use that method, or something different from SparseTree?
