Class AbstractTreeTableModel

java.lang.Object

de.javagl.treetable.AbstractTreeTableModel

All Implemented Interfaces:

TreeTableModel, TreeModel

public abstract class AbstractTreeTableModel
extends Object
implements TreeTableModel

An abstract implementation of the TreeTableModel interface, handling the list of listeners.

Note: In order to actually display the JTree in one column of the JTreeTable, implementors of this class have to return the TreeTableModel.class as the respective column class in their implementation of the TreeTableModel.getColumnClass(int) method:

 public Class<?> getColumnClass(int column)
 {
     if (column == columnThatShouldContainTheTree)
     {
         return TreeTableModel.class;
     }
     // Return other types as desired:
     return Object.class;
 }
