All Implemented Interfaces:

JCTreeTableModel, Serializable, TreeModel

public class EmptyTreeTableModel

extends DefaultTreeModel

implements JCTreeTableModel

An empty tree table model used by JCTreeTable and JCTreeExplorer in their default constructors. This model provides a simple tree table when invoked at design time, and does nothing under normal conditions. This way the tree table or tree explorer can display some values in a visual designer environment.

Constructor Detail

EmptyTreeTableModel

public EmptyTreeTableModel(TreeNode root)

Constructs a tree table model.

Parameters:

root - a TreeNode object that is the root of the tree

EmptyTreeTableModel

public EmptyTreeTableModel(TreeNode root,
                           boolean asksAllowsChildren)

Constructs a tree table model.

Parameters:

root - a TreeNode object that is the root of the tree

asksAllowsChildren - a boolean, false if any node can have children, true if each node is asked to see if it can have children

Method Detail

makeDefaultTree

public static MutableTreeNode makeDefaultTree()

Creates a simple tree model.

Returns:

The root of the new default tree

getValueAt

public Object getValueAt(Object node,
                         int column)

Returns a simple string object if running at design time, otherwise returns null.

Specified by:

getValueAt in interface JCTreeTableModel

Parameters:

node - The node for which the value is wanted

column - The column of the node for which the value is wanted

Returns:

The value the given column of the given node

isCellEditable

public boolean isCellEditable(Object node,
                              int column)

Returns that the treeTable is not editable.

Specified by:

isCellEditable in interface JCTreeTableModel

Parameters:

node - The node for which the cell editable value is wanted

column - The column of the node for which the cell editable value is wanted
