Constructor Detail

CircleBehavior

public CircleBehavior(CircleListener zili)

Creates a new behavior for selecting circle areas.

Parameters:

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

Method Detail

getListener

public ToolListener getListener()

Description copied from interface: IBehavior

Gets the ToolListener used by this behavior to perform actions on the associated MapControl object.

Specified by:

getListener in interface IBehavior

Specified by:

getListener in class Behavior

Returns:

the ToolListener used by this behavior

mouseDragged

public void mouseDragged(java.awt.event.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:
