Constructor Detail

PolylineBehavior

public PolylineBehavior(PolylineListener mli)

Creates a new behavior for drawing a polyline by its vertexes.

Parameters:

mli - listener used to permit this object to work with the associated MapControl

Method Detail

paintComponent

public void paintComponent(MapControlDrawer mapControlDrawer)

Description copied from interface: IBehavior

Method executed in real-time, when user is working with a tool on the associated MapControl object, repainting the MapControl's image.

Returns immediately in all cases, even if the complete image has not yet been loaded.

This method will be implemented according to the specific nature of each behavior, and its extra and particular features.

Specified by:

paintComponent in interface IBehavior

Specified by:

mousePressed in interface IBehavior

Overrides:

mousePressed in class Behavior

Throws:

BehaviorException - any exception processing the action associated to a mouse pressed event, by the IBehavior object

BehaviorException - any exception processing the action associated to a mouse dragged event, by the IBehavior object

See Also:

MouseMotionListener.mouseDragged(java.awt.event.MouseEvent)

changeLastPoint

protected void changeLastPoint(Point2D p)

Changes the last point added of the polyline.

Parameters:

p - a point which will replace the last added to the polyline
