Typical usage: To lay out only a portion of a document, you will need to construct a
GoLayoutTreeNetwork, initialize it with just the nodes and links that you want to use, and set the
Network property. Read the GoLayout User Guide for more details.
GoDocument doc = goView1.Document;
doc.StartTransaction();
GoLayoutTree layout = new GoLayoutTree();
layout.Document = doc;
layout.Angle = 90;
layout.NodeSpacing = 15;
layout.LayerSpacing = 40;
// ...maybe set other properties, such as those of layout.AlternateDefaults ...
layout.PerformLayout();
doc.FinishTransaction("layout");
GoDocument doc = goView1.Document;
doc.StartTransaction();
GoLayoutTree layout = new GoLayoutTree();
layout.Document = doc;
layout.Network = layout.CreateNetwork();
// if you want to start off with the network representing the complete document,
// and then remove the nodes (or links) that you don't want:
layout.Network.AddNodesAndLinksFromCollection(doc, true);
foreach (GoObject obj in doc) {
if (...obj is a node that you want to exclude from the layout...) {
layout.Network.DeleteNode(obj); // there is also a DeleteLink method
}
}
layout.Angle = 90;
layout.NodeSpacing = 15;
layout.LayerSpacing = 40;
// ...maybe set other properties...
layout.PerformLayout();
doc.FinishTransaction("layout");
