Constructor Details

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 Details

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

Overrides:

paintComponent in class Behavior

See Also:

• Graphics.drawImage(java.awt.Image, int, int, java.awt.image.ImageObserver)

mouseClicked

public void mouseClicked(MouseEvent e)
                  throws BehaviorException

Specified by:

mouseClicked in interface IBehavior

Overrides:

mouseClicked in class Behavior

Throws:

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

See Also:

• MouseListener.mouseClicked(java.awt.event.MouseEvent)

public void mouseDragged(MouseEvent e)
                  throws BehaviorException

Specified by:

mouseDragged in interface IBehavior

Overrides:

mouseDragged in class Behavior

Throws:

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

Specified by:

mouseMoved in interface IBehavior

Overrides:

mouseMoved in class Behavior

Throws:

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

See Also:

• MouseMotionListener.mouseMoved(java.awt.event.MouseEvent)
