Class DefaultTreeTableModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      org.openbp.swing.components.treetable.SimpleTreeTableModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel, javax.swing.tree.TreeModel, TreeTableModel

public class DefaultTreeTableModel
extends SimpleTreeTableModel

The DefaultTreeTable model implements the TreeTableModel interface and extends the AbstractTableModel. The TreeTableModel combines the TableModel and TreeModel interfaces, thus providing a combined model for the JTreeTable. The model structure for the tree table is based on the DefaultTreeTableNode, that implements functionality for holding all the column objects of the table in a tree node. This provides a mechanism where the DefaultTreeTableNode presents both a table row and a tree node. In order to build the structure for the tree table, a DefaultTreeTableNode containing all the column objects should be added to the DefaultTreeTableModel with the addNode() method. It is important to note that column value (0) is the value used to display the value in the tree. This object may either be a String, or a JLabel. In the case of a String, the String will be embedded into a JLabel with the appropriate system icon for open, closed or leaf nodes. In the case of a JLabel, this label will be used with the icon implemented in the label.

Constructor Detail

DefaultTreeTableModel

public DefaultTreeTableModel(DefaultTreeTableNode root)

Default Constructor

Parameters:

root - The root node for the TreeTable

Method Detail

getColumnCount

public int getColumnCount()

Returns the number of columns contained in the table.

Specified by:

getColumnCount in interface javax.swing.table.TableModel

Overrides:

getColumnCount in class SimpleTreeTableModel

Returns:

The number of columns contained in the table

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

This sets the user object of the TreeNode identified by path and posts a node changed. If you use custom user objects in the TreeModel you're going to need to subclass this and set the user object of the changed node to something meaningful.

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Overrides:

valueForPathChanged in class SimpleTreeTableModel

Parameters:

path - The treePath for identification

newValue - The new user object

addNode

public void addNode(DefaultTreeTableNode parent,
                    DefaultTreeTableNode child)

Adds a new node to the tree. The node is of type DefaultTreeTableNode, thus should containe all the column objects.

Parameters:

parent - The parent node to which the specified node is to be added. The parent the parent is null, then the node will use the parent set within the node, and if this is null, then the node will added to the root node.

child - Node to add

removeNode

public void removeNode(DefaultTreeTableNode node)

Removed the specified node from the model. Note!: If the node contains children, the these will also be removed.

Parameters:

node - The node to be removed from the model
