Method Summary

Enumeration	children() Returns the children of the reciever as an Enumeration.
String	getActionCommand() Returns the Action command string associated with this node
boolean	getAllowsChildren() Returns true if the receiver allows children.
TreeNode	getChildAt(int childIndex) Returns the child TreeNode at index childIndex.
int	getChildCount() Returns the number of children TreeNodes the receiver contains.
int	getIndex(TreeNode node) Returns the index of node in the receivers children.
TreeNode	getParent() Returns the parent TreeNode of the receiver.
boolean	isLeaf() Returns true if the receiver is a leaf.
