Article: Gantt Charts With JXTreeTable
today I published an article "Gantt Charts With JXTreeTable" at http://articles.lightdev.com/gantt/gantt_article.pdf
It describes how to utilize a custom tree cell renderer to implement display and manipulation of gantt charts with JXTreeTable. It also shows a way to customize date editing, explains how to build a custom data model for JXTreeTable and applies drag and drop to JXTreeTable.
The article is accompanied with source codes and a working binary.
