 package org.abego.treelayout.demo.swing;
 
 
 
Demonstrates how to use the org.abego.treelayout.TreeLayout to render a tree in a Swing application.

Intentionally the sample code is kept simple. I.e. it does not include stuff like anti-aliasing and other stuff one would add to make the output look nice.

Shows a dialog with a tree in a layout created by org.abego.treelayout.TreeLayout, using the Swing component TextInBoxTreePane.
 
 	public static void main(String[] args) {
 		// get the sample tree
 		String treeName = (args.length > 0) ? args[0] : "";
 				
 		// setup the tree layout configuration

 		double gapBetweenNodes = 10;
 				gapBetweenLevelsgapBetweenNodes);
 
		// create the NodeExtentProvider for TextInBox nodes
		// create the layout

		// Create a panel that draws the nodes and edges and show the panel
