Class TreeMapNode

java.lang.Object
  net.sf.jtreemap.ktreemap.TreeMapNode

public class TreeMapNode
extends java.lang.Object

Node of a KTreeMap.
If the node is a branch, only the label is set.
If the node is a leaf, we need a label, a weight and a value.

You can also use a TreeMapNode in a JTree.

Constructor Summary

TreeMapNode(java.lang.Object value)
Constructor for a branch

TreeMapNode(java.lang.Object value, double weight)
Constructor for a leaf.

TreeMapNode	getActiveLeaf(int x, int y) get the active leaf.
TreeMapNode	getActiveLeaf(org.eclipse.swt.graphics.Point position) get the active leaf.
static int	getBorder() Get the max border between two nodes of the same level.
org.eclipse.swt.graphics.Rectangle	getBounds()
TreeMapNode	getChild(int x, int y) get the first child which fits the position.
TreeMapNode	getChild(org.eclipse.swt.graphics.Point position) get the first child which fits the position.
