All Implemented Interfaces:

public class MakeConnectionAction

extends org.eclipse.jface.action.Action

implements org.eclipse.gef.requests.CreationFactory

This action tells GEF to use its Creation tool to allow the user to create a new Link. To this end, it is also a creation factory for Link objects.

The actual creation of an Anchor happens when the user draws out an area on the screen, and is handled as a part of the GEF policy LOLinkEditPolicy.getConnectionCreateCommand(org.eclipse.gef.requests.CreateConnectionRequest).
