Constructor Details

CircleBehavior

public CircleBehavior(AbstractCircleListener zili)

Creates a new behavior for selecting circle areas.

Parameters:

zili - 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.
