Examples of javax.swing.tree.MutableTreeNode

javax.swing.tree.MutableTreeNode
Defines the requirements for a tree node object that can change -- by adding or removing child nodes, or by changing the contents of a user object stored in the node. @see DefaultMutableTreeNode @see javax.swing.JTree @author Rob Davis @author Scott Violet
