Recursive Group Layout
This demo shows how to use the
Recursive Group Layout.
The Recursive Group Layout algorithm recursively
traverses a hierarchically organized graph in a bottom-up fashion and applies a specified
layout algorithm to the contents (direct children) of each group node.
In this demo for every group node a different layout algorithm is used:
As the child nodes of group node 4 already have fixed layout values in the graph source,
RecursiveGroupLayout#NULL_LAYOUT is used, as it does not alter the layout
of the child nodes and is only used to calculate the size of the group node itself.
The content of groups without an assigned layout algorithm and the toplevel hierarchy is
arranged with the
core layout algorithm, if one has been
The configuration of which algorithm to use for which group node is done by setting an
Item Mapping to the
groupNodeLayouts property of
