java.lang.Object

org.gvsig.hyperlink.app.extension.LinkListener

All Implemented Interfaces:

PointListener, ToolListener

public class LinkListener
extends Object
implements PointListener

Listener that implements PointListener to show the information of the HyperLink of the layer, if the actual layer allows it. When the user selects the tool and make one clic with the mouse throws an event to create Panels with the information of the associated HyperLink to the layer. Creates one panel for URI provided, to load the information.
