Class Subgraph

public class Subgraph extends Node
A Node which may contain other nodes. A Subgraph is a compound or container node. It may have incoming and outgoing edges just like a node. Subgraphs are used in CompoundDirectedGraphs. A proper layout of a compound graph ensures that all of a subgraph's children are placed inside its rectangular region. Nodes which do not belong to the subgraph must be placed outside that region.

A Subgraph may contain another Subgraph.

A Subgraph has additional geometric properties which describe the containing box. They are:

  • insets - the size of the subgraph's border. A subgraph is typically rendered as a thin rectangular box. Sometimes this box is labeled or decorated. The insets can be used to reserve space for this purpose.
  • innerPadding - the amount of empty space that must be preserved just inside the subgraph's border. This is the minimum space between the border, and the children node's contained inside the subgraph.

    • members

      public NodeList members
      The children of this subgraph. Nodes may not belong to more than one subgraph.
    • insets

      public Insets insets
      The space required for this subgraph's border. The default value is undefined.
    • innerPadding

      public Insets innerPadding
      The minimum space between this subgraph's border and it's children.
