## Detailed Description

**TreeReingoldAndTilfordExtended.h** - An implementation of a hierarchical tree layout.

This plugin is an implementation of the hierarchical tree layout algorithm first published as:

E.M. Reingold and J.S. Tilford, \
\
  'Tidier Drawings of Trees', \
\
  'IEEE Transactions on Software Engineering' \
\
  pages '223--228' \
\

**HISTORY**

- •

  21/02/2000 Verson 0.0.1: Initial release

- •

  06/11/2002 Verson 0.0.2: Documentation and code clean up

- •

  06/01/2005 Verson 0.0.3: Code refactoring, management of : orienetation, parameters

**Note:**

This algorithm only works on trees.\
\
  Let n be the number of nodes, the algorithm complexity is in O(n).\
\
  It extends the original Reingold and Tilford by providing managment of different node size and different edge length. \

 The algorithm use the (Size)'viewSize' property for element size and the (int)'treeEdgeLength' for the edge length.
