Hierarchical Nesting (Incremental)
This demo shows how to nicely lay out the newly loaded nodes when expanding folded groups
in graph.
Each time a folded group is expanded for the first time, all of its child nodes are
retrieved and then marked as incremental using
HierarchicalLayoutData.incrementalNodes. The from sketch mode of the layout
algorithm then ensures that the currently visible part of the graph is well-organized
while remaining similar to the previous arrangement.
Things to Try
-
Expand or collapse a group node with the
+
or
-
button.
Demos
See the Hierarchical Nesting Demo
for a hierarchical nested graph built on a pre-defined set of nodes without subsequent
node retrieval.
