allowsChildren, children, EMPTY_ENUMERATION, parent, userObject

Constructor Summary

protected	XTreeNode(Object userObject) Creates a tree node with no parent, no children, initialized with the specified user object.
	XTreeNode(TreeModel treeModel, Object userObject, boolean allowsChildren) construct the node with the tree model, the tree model must always be passed in the constructor, each node knows it's model from the start.

Method Summary

void	addNotify(MutableTreeNode newChild) add the child node, and notify the model if it is a default tree model
protected abstract void	doInitialize() do the initialization
int	getDepth() get the distance of this node from the root node the children of the root node have a depth of 1.
XTreeNode	getNodeChildAt(int index) type cast the child ot an onode
TreeModel	getTreeModel() return the tree model
void	initialize() lazy initialization
void	insertNotify(MutableTreeNode newChild, int index) insert the child node, and notify the model if it is a default tree model
boolean	isExpanded() return the expanded state.
boolean	isInitialized()
void	reinitialize() reinitialize
void	removeAllChildrenNotify() remove all children
void	setExpanded(boolean expanded)
void	setInitialized(boolean initialized)
void	setTreeModel(TreeModel treeModel) Set the tree model as tree model of current node.

Constructor Detail

XTreeNode

protected XTreeNode(Object userObject)

Creates a tree node with no parent, no children, initialized with the specified user object. For default the XTreeTableNode doesn't allow children.

Parameters:

userObject - an Object provided by the user that constitutes the node's data

XTreeNode

public XTreeNode(TreeModel treeModel,
                 Object userObject,
                 boolean allowsChildren)

construct the node with the tree model, the tree model must always be passed in the constructor, each node knows it's model from the start.

Parameters:

treeModel -

Method Detail

initialize

public void initialize()

lazy initialization

Specified by:

initialize in interface LazyNode

doInitialize

protected abstract void doInitialize()

do the initialization

reinitialize

public void reinitialize()

reinitialize

isInitialized

public boolean isInitialized()

Returns:

Returns the initialized.

setInitialized

public void setInitialized(boolean initialized)

getTreeModel

public TreeModel getTreeModel()

return the tree model

Returns:

setTreeModel

public void setTreeModel(TreeModel treeModel)

Set the tree model as tree model of current node.

Parameters:

treeModel - The tree model of the whole tree.

getNodeChildAt

public XTreeNode getNodeChildAt(int index)

type cast the child ot an onode

Parameters:

index -

Returns:

getDepth

public int getDepth()

get the distance of this node from the root node the children of the root node have a depth of 1.

Overrides:

getDepth in class DefaultMutableTreeNode

Returns:

Returns the depth.

isExpanded

public boolean isExpanded()

return the expanded state. the expanded state is held in the model because certain tree implementations perform expand / collapse at the model level.

Returns:

Returns the expanded.

setExpanded

public void setExpanded(boolean expanded)

Parameters:

expanded - The expanded to set.

insertNotify

public void insertNotify(MutableTreeNode newChild,
                         int index)

insert the child node, and notify the model if it is a default tree model

Parameters:

newChild -

index -

removeAllChildrenNotify

public void removeAllChildrenNotify()

remove all children

addNotify

public void addNotify(MutableTreeNode newChild)

add the child node, and notify the model if it is a default tree model

Parameters:

newChild -

parent -

index -
