N - The node class for the trees and graphsE - The edge class for graph edgespublic class ForceDirectedDisplay<N,E> extends PrefuseGraphDisplay<N,E>
Display which arranges the graph nodes using a force-directed layout to arrange the nodes. The display attempts to arrange the nodes in a compact arrangement with more connected nodes arranged tightly together. This means that the arrangement may continually update to find the optimum arrangement.
The display also supports several interactive methods. When a node is double-clicked, it is selected. The node also becomes fixed, and will not move around as the rest of the graph rearranges itself When the cursor moves over a node, that node is shown in red. All immediate neighbors - those nodes which are adjacent to the node - are shown in orange. Clicking and holding the left mouse button when not over a node allows the user to pan the display. Holding the right mouse button and moving the mouse up and down, or using the middle mouse dial, will zoom the display in and out.
This class is an adaptation of the prefuse.demos.GraphView class as a Prajna display, and includes significant code segments from the original class. The Prajna Project respects all rights of the original class.
