All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, EventListener, Accessible, MapBoundsListener, MapLayerListListener, MapPane, RenderingExecutorListener

Direct Known Subclasses:

JLayeredMapPane, JMapPane
```
public abstract class AbstractMapPane
extends JPanel
implements MapPane, RenderingExecutorListener, MapLayerListListener, MapBoundsListener
```
Base class for Swing map panes. It extends Swing's JPanel class and handles window sizing and repainting as well as redirecting mouse events. It also provides basic implementations of all interface methods. Sub-classes must implement drawLayers(boolean) and override JComponent.paintComponent(java.awt.Graphics).
