Class ComponentPaintCache

java.lang.Object

games.stendhal.client.gui.ComponentPaintCache

public class ComponentPaintCache
extends Object

Cached painting for components that need it. Components using this need to implement the Cacheable interface, and override the paint method to something like:

 public void paint(Graphics g) {
        cache.paintComponent(g);
        paintChildren(g);
 } 

Also, the components need to call cache.invalidate() should the component need a proper redraw. Size changes are automatically handled.
