Class JPassiveRenderer

java.lang.Object
  org.jdesktop.swing.animation.rendering.JPassiveRenderer

All Implemented Interfaces:

org.jdesktop.core.animation.rendering.JRenderer<JRendererPanel>

public class JPassiveRenderer
extends Object
implements org.jdesktop.core.animation.rendering.JRenderer<JRendererPanel>

Manages passive rendering on a Swing JRendererPanel.

To use this renderer a client constructs a JRendererPanel and passes it to the constructor with a JRendererTarget implementation and a timing source. A typical sequence would be

 JFrame frame = new JFrame("Renderer Demonstration");
 final JRendererPanel on = new JRendererPanel();
 frame.setContentPane(on);
 final JRendererTarget<GraphicsConfiguration, Graphics2D> target = this;
 final TimingSource timingSource = new SwingTimerTimingSource();
 JRenderer renderer = new JPassiveRenderer(on, target, timingSource);
 timingSource.init();
 

In the above snippet on will be rendered to. The enclosing instance, this, implements JRendererTarget and will be called to customize what is displayed on-screen.
