The selection interactor for drag-selecting nodes

_nodeCreator

private BasicGraphController.NodeCreator _nodeCreator

The interactor for creating new nodes

_edgeCreator

private EdgeCreator _edgeCreator

Constructor Detail

BasicGraphController

public BasicGraphController()

Create a new basic controller with default node and edge controllers.

Method Detail

initializeInteraction

protected void initializeInteraction()

Initialize all interaction on the graph pane. This method is called by the setGraphPane() method of the superclass. This initialization cannot be done in the constructor because the controller does not yet have a reference to its pane at that time.
