All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, RenderTarget

public final class RenderPanel
extends Canvas
implements RenderTarget

Ein Render-Panel, das als Zeichenfläche für die Engine dient.

Diese Klasse erweitert Canvas und implementiert RenderTarget, um eine effiziente Darstellung von Grafiken mithilfe von Buffer-Strategien zu ermöglichen. Das Panel verwendet Double-Buffering, um Flackern beim Rendern zu vermeiden.

Das Panel muss nach dem Sichtbarwerden des Fensters initialisiert werden, indem allocateBuffers() aufgerufen wird, um die Buffer-Strategie zu erstellen.
