Class PanamaGLCanvasSupport

java.lang.Object

org.jzy3d.plot3d.rendering.canvas.PanamaGLCanvasSupport

public class PanamaGLCanvasSupport
extends Object

Toolkit-agnostic composition helper shared by all IPanamaGLCanvas implementations (Swing, JavaFX, SWT). It holds the non-UI state of a PanamaGL canvas (view, renderer, animator, GLCanvas) and exposes the lifecycle operations that do not depend on the hosting component. Toolkit-specific canvases compose with this class to avoid duplicating the view/renderer/animator wiring.
