org.gvsig.app.project.documents.view.toolListeners.MeasureListener

All Implemented Interfaces:

PolylineListener, ToolListener

public class MeasureListener
extends MeasureListenerImpl

Listener for calculating distances using vertexes of a polyline, defined in the associated MapControl object, and displaying that information at the status bar of the application's main frame.

Calculates and displays:

• Distance of the last segment of the polyline.
• Accumulated distance of all segments of the polyline.
