removeTreeModelListener in interface TreeModel

fireTreeNodesChanged

protected void fireTreeNodesChanged(Object source,
                                    Object[] path,
                                    int[] childIndices,
                                    Object[] children)

fireTreeNodesInserted

protected void fireTreeNodesInserted(Object source,
                                     Object[] path,
                                     int[] childIndices,
                                     Object[] children)

fireTreeNodesRemoved

protected void fireTreeNodesRemoved(Object source,
                                    Object[] path,
                                    int[] childIndices,
                                    Object[] children)

fireTreeStructureChanged

protected void fireTreeStructureChanged(Object source,
                                        Object[] path,
                                        int[] childIndices,
                                        Object[] children)

getColumnClass

public Class getColumnClass(int column)

Description copied from interface: TreeTableModel

Returns the type for column number column.

Specified by:

getColumnClass in interface TreeTableModel

isCellEditable

public boolean isCellEditable(Object node,
                              int column)

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

setValueAt

public void setValueAt(Object aValue,
                       Object node,
                       int column)

Description copied from interface: TreeTableModel

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

Specified by:

setValueAt in interface TreeTableModel

getPathToRoot

public TreeNode[] getPathToRoot(TreeNode aNode)

Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.

Parameters:

aNode - the TreeNode to get the path for

getPathToRoot

protected TreeNode[] getPathToRoot(TreeNode aNode,
                                   int depth)

Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.

Parameters:

aNode - the TreeNode to get the path for

depth - an int giving the number of steps already taken towards the root (on recursive calls), used to size the returned array

Returns:

an array of TreeNodes giving the path from the root to the specified node
