Class PolygonSelectionListener

java.lang.Object
  org.gvsig.fmap.mapcontrol.tools.PolygonSelectionListener

All Implemented Interfaces:

PolylineListener, ToolListener

public class PolygonSelectionListener
extends Object
implements PolylineListener

Listener that selects all features of the active and vector layers which intersect with the defined polygon area in the associated MapControl object.

The selection will be produced after user finishes the creation of the polyline.

Constructor Summary

PolygonSelectionListener(MapControl mc)
Creates a new PolygonSelectionListener object.

Method Summary

boolean	cancelDrawing() Determines if the drawing process that this tool executes on the MapControl instance could be canceled or not.
Image	getImageCursor() Gets the Cursor associated to this tool.
void	pointFixed(MeasureEvent event) Called when user executes a mouse click and selects a vertex of the polyline.
void	points(MeasureEvent event) Called when user moves the mouse after selecting a vertex of the polyline.
void	polylineFinished(MeasureEvent event) Called when user executes a double click with the mouse, finishing the drawn of the polyline.

Constructor Detail

PolygonSelectionListener

public PolygonSelectionListener(MapControl mc)

Creates a new PolygonSelectionListener object.

Parameters:

mc - the MapControl where is drawn the polyline

Method Detail

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

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

points

public void points(MeasureEvent event)
            throws BehaviorException

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

Throws:

BehaviorException - will be thrown when fails the process of this tool

pointFixed

public void pointFixed(MeasureEvent event)
                throws BehaviorException

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

Throws:

BehaviorException - will be thrown when fails the process of this tool

polylineFinished

public void polylineFinished(MeasureEvent event)
                      throws BehaviorException

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

Throws:

BehaviorException - will be thrown when fails the process of this tool
