JTreeTable

A JTreeTable is a combination of a JTree and a JTable - a component capable of both expanding and contracting rows, as well as showing multiple columns of data.

This component always displays a tree in the first column and the additional data in the next columns. You can see its usage in a very simple example of the directory tree.

The code in this class is derived from the source from the JTreeTable article that can be found at: http://java.sun.com/products/jfc/tsc/articles/treetable2/index.html.

This component has the next features:

• it inherits from its parent class ability to hide / show columns
• also inherits possible "zebra" look
• the tree is always painted in the first column
• as its model you must use TreeTableModel or subclasse it
• supports data lazy loading
• descendants of the TreeTableNode are only nodes acceptable in the JTreeTable

The TreeTableModel which is used as model for JTreeTable, extends javax.swing.tree.DefaultTreeModel to meet the requirements for model for JTreeTable.

The TreeTableNode is hierarchical node for the JTreeTable. It inherits lazy loading possibility from the ExplorableTreeNode and adds the methods for get / set value for required column.
