Interface TreeTableModel<R,T>

All Known Implementing Classes:

AbstractTreeTableModel, KeyStrokeTreeTableModel

public interface TreeTableModel<R,T>

The TreeTableModel interface specifies the methods the JTreeTable will use to interrogate a tabular tree data model.

The JTreeTable can be set up to display any data model which implements the TreeTableModel interface with a couple of lines of code:

      TreeTableModel myData = new MyTreeTableModel();
      JTreeTable treeTable = new JTreeTable(myData);
