Class Subgraph

org.eclipse.draw2d.graph.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.
