  • Field Details

    • mapCtrl

      protected MapControl mapCtrl
      Reference to the MapControl object that uses.

  • Constructor Details

    • MeasureListenerImpl

      public MeasureListenerImpl(MapControl mc)

      Creates a new listener for calculating the length of a polyline.

      Parameters:
      mc - the MapControl where is calculated the length

  • Method Details

    • points

      public void points(MeasureEvent event)
      Description copied from interface: PolylineListener

      Called when user moves the mouse after selecting a vertex of the polyline.

      Each kind of polyline listener calculates different information with the data of the MeasureEvent, according its nature.

      Specified by:
      points in interface PolylineListener
      Parameters:
      event - information about the mouse event, and geometry data of the polyline

    • getImageCursor

      public Image getImageCursor()
      Description copied from interface: ToolListener

      Gets the Cursor associated to this tool.

      Specified by:
      getImageCursor in interface ToolListener
      Returns:
      component with the bitmap associated to this tool

    • pointFixed

      public void pointFixed(MeasureEvent event)
      Description copied from interface: PolylineListener

      Called when user executes a mouse click and selects a vertex of the polyline.

      Specified by:
      pointFixed in interface PolylineListener
      Parameters:
      event - information about the mouse event, and geometry data of the polyline

    • cancelDrawing

      public boolean cancelDrawing()
      Description copied from interface: ToolListener

      Determines if the drawing process that this tool executes on the MapControl instance could be canceled or not.

      Specified by:
      cancelDrawing in interface ToolListener
      Returns:
      true if is cancellable; otherwise returns false

    • polylineFinished

      public void polylineFinished(MeasureEvent event)
      Description copied from interface: PolylineListener

      Called when user executes a double click with the mouse, finishing the drawn of the polyline.

      All features of the active and vector layers of the associated MapControl object that their area intersect with the polygonal area defined in the event, will be selected.

      Specified by:
      polylineFinished in interface PolylineListener
      Parameters:
      event - information about the mouse event, and geometry data of the polyline
