Constructor Detail

WebTreeModel

public WebTreeModel(E root)

Constructs tree model with a specified node as root.

Parameters:

root - TreeNode object that is the root of the tree

WebTreeModel

public WebTreeModel(E root,
                    boolean asksAllowsChildren)

Constructs tree model with a specified node as root.

Parameters:

root - TreeNode object that is the root of the tree

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

Method Detail

getRootNode

public E getRootNode()

Returns root node.

Returns:

root node

insertNodesInto

public void insertNodesInto(java.util.List<E> children,
                            E parent,
                            int index)

Inserts a list of child nodes into parent node.

Parameters:

children - list of new child nodes

parent - parent node

index - insert index

insertNodesInto

public void insertNodesInto(E[] children,
                            E parent,
                            int index)

Inserts a list of child nodes into parent node.

Parameters:

children - array of new child nodes

parent - parent node

index - insert index

removeNodesFromParent

public void removeNodesFromParent(java.util.List<E> nodes)

Removes specified nodes from tree structure.

Parameters:

nodes - nodes to remove

removeNodesFromParent

public void removeNodesFromParent(E node)

Removes all child nodes under the specified node from tree structure.

Parameters:

node - node to remove children from

removeNodesFromParent

public void removeNodesFromParent(E[] nodes)

Removes specified nodes from tree structure.

Parameters:

nodes - nodes to remove

valueForPathChanged

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

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Overrides:

valueForPathChanged in class javax.swing.tree.DefaultTreeModel

updateNode

public void updateNode(E node)

Forces tree node to be updated.

Parameters:

node - tree node to be updated

updateNodeStructure

public void updateNodeStructure(E node)

Forces tree node to be updated.

Parameters:

node - tree node to be updated

updateTree

public void updateTree()

Forces update of all visible node sizes and view. This call might be useful if renderer changes dramatically and you have to update the whole tree.
