How to arrange new node preserving previous layout (Read 3327 times)

Raju Guest	How to arrange new node preserving previous layout Jan 17^th, 2006 at 4:25am	Print Post
	I am arranging nodes in flowchart using Spring Layout. When I add new node programatically and call arrange method of layout, it arranges all other node. But i want previous node position sholud not be disturbed. So I set Igonre layout property of nodes to true. But this causes overlapping of new node. Suggest some solution.

	I do not think that's possible. The SpringLayout simulates physical repulsion or attraction between nodes, depending on whether they are linked. If some nodes are ignored, they will not have any effect on the not-ignored ones so they will probably overlap. You might try placing the new node somewhere outside the current graph boundaries and run the layout for only a few iterations, e.g. 5-10. That will move all other nodes too but should have a minimal effect on them.
