Using the NodeLinkDemo45 got us a long way – it’s been awesome to use!
Now I’m trying to add subgraphs and I’m not sure what subgraph fields to bind AND I can see that the contained nodes aren’t saved, and I suspect the links are not being saved either.
Is there a sample project that saves/loads SubGraphs? Sadly, SubGraphApp45 does not.
From NodeLinkDemo (XmlSubGraphTextNode)
GoSubGraph sg = new GoSubGraph();
sg.Port = new GoPort();
t = new GoXmlBindingTransformer("SubGraph", sg);
t.HandlesNamedPorts = true; // generate attributes for each of the named ports, specifying their IDs
t.HandlesChildren = true; // generates children and consumes them by adding to the subgraph
t.HandlesChildAttributes = true; // make sure reading/writing each child calls these Generate/ConsumeChildAttributes methods
t.HandlesSubGraphCollapsedChildren = true; // generate SavedBounds and SavedPath info for children if subgraph is collapsed
t.AddBinding("Text", "Text");
t.AddBinding("xy", "Position");
rw.AddTransformer(t);
Thanks, that helped a lot!
That saves the data out properly, but hit a little snag on reloading all nodes in or connected to a Subgraph are losing their labels (other custom properties are in tact).
So it appears I have to change:
t.AddBinding(“label”, “Text”);
to:
t.AddBinding(“Text”, “Text”);
And then it all works, but this means all my saved graphs are needing a conversion. :-(
I can write the conversion, but it’d be nice if SubGraphs Transformer handled it.
Links (and their custom properties) all appear to be working fine.
Can you post a sample of your “saved” XML?
Sorry – the applied fix cleared the issue and it’s all working… and then I had a long Christmas break.
Don’t have any of the non-functional xml around any more.
