Nested Class Summary

class

TreeTableModelNode.Node A Node is a derivative of the File class - though we delegate to the File object rather than subclassing it.

ZERO

public static final java.lang.Integer ZERO

Constructor Detail

TreeTableModelNode

public TreeTableModelNode()

Creates a TreeTableModelNode rooted at File.separator, which is usually the root of the file system. This does not load it, you should invoke reloadChildren with the root to start loading.

TreeTableModelNode

public TreeTableModelNode(DataModel rootModel)

Creates a TreeTableModelNode with the root being rootPath. This does not load it, you should invoke reloadChildren with the root to start loading.

TreeTableModelNode

public TreeTableModelNode(DataModel rootModel,
                          javax.swing.table.TableModel aTableModel)

Method Detail

getChildCount

public int getChildCount(java.lang.Object node)

Returns the number of children of node.

getChild

public java.lang.Object getChild(java.lang.Object node,
                                 int i)

Returns the child of node at index i.

isLeaf

public boolean isLeaf(java.lang.Object node)

Returns true if the passed in object represents a leaf, false otherwise.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Overrides:

isLeaf in class AbstractTreeTableModel

getColumnCount

public int getColumnCount()

Return the number of columns.

getColumnName

public java.lang.String getColumnName(int columnIndex)

Returns the name for a particular column.

getColumnClass

public java.lang.Class getColumnClass(int column)

Returns the class for the particular column.

Specified by:

getColumnClass in interface TreeTableModel

Overrides:

getColumnClass in class AbstractTreeTableModel

getValueAt

public java.lang.Object getValueAt(java.lang.Object node,
                                   int columnIndex)

Returns the value of the particular column.

setValueAt

public void setValueAt(java.lang.Object value,
                       java.lang.Object node,
                       int columnIndex)

Description copied from interface: TreeTableModel

Sets the value for node node, at column number column.

Specified by:

setValueAt in interface TreeTableModel

Overrides:

setValueAt in class AbstractTreeTableModel

isCellEditable

public boolean isCellEditable(java.lang.Object node,
                              int columnIndex)

Description copied from class: AbstractTreeTableModel

By default, make the column with the Tree in it the only editable one. Making this column editable causes the JTable to forward mouse and keyboard events in the Tree column to the underlying JTree.

Specified by:

isCellEditable in interface TreeTableModel

Overrides:

isCellEditable in class AbstractTreeTableModel

reloadChildren

public void reloadChildren(java.lang.Object node)

Reloads the children of the specified node.

Specified by:

reloadChildren in class AbstractTreeTableModel

Parameters:

level - the depth of the tree

getPath

public java.lang.String getPath(java.lang.Object node)

Returns the path node represents.

getModel

protected DataModel getModel(java.lang.Object node)

getChildren

protected java.lang.Object[] getChildren(java.lang.Object node)

nodeLoader

public void nodeLoader(TreeTableModelNode.Node node)

loadChildren

protected void loadChildren(TreeTableModelNode.Node node)
