public class ExamplePanel
extends BasicGraphPanel

This is an example of how to extend the BasicGraphPanel to draw nodes and edges any way you want. Refer to the Node and Edge documentation to see which parameters you can use. In this example, paintNode is extended and uses Node.getColor() to create a button-like effect.

Constructor

Parameters:

ms - default settings

Method Detail

paintEdge

public void paintEdge(java.awt.Graphics2D g,
                      Edge e)

Overridden paintEdge method. This version just draws a line. You can try paths, icons or anything you like.

Overrides:

paintEdge in class BasicGraphRenderer

Parameters:

g - graphics2d context

e - the current edge

paintNode

public void paintNode(java.awt.Graphics2D g,
                      Node n)

Overridden paintNode method. Paints two ellipses with a gradient based on the node color. The button effect is created by using opposite gradients. If you want the dragged node to be painted differently, override paintPick. If you want the fixed nodes to be painted differently, check for Node.isFixed.

Overrides:

paintNode in class BasicGraphRenderer

Parameters:

g - Graphics2D

n - Node n
