The project is going slowly. There have not been many SVN updates for a long time. Recently I added the node coloring to the project.

there are many refactors incoming, so please be advised that methods and fields are subject to be obsoleted or removed.

Latest SVN Update: Feb. 13 - 2013

Project Description

Currently, these features are available:

  • Create a NodeGraphPanel into your form and setup look and feel (colors, link hardness, etc.)
  • Navigate NodeGraphPanel: panning, zooming.
  • Add nodes to the NodeGraphPanel, move them, multiple select them.
  • Create and destroy links between nodes.
