Method Detail

paint

public abstract void paint(java.awt.Graphics g)

Override this method in your subclasses to paint a single frame. Any exceptions thrown during paint will be sent to the org.jdesktop.jdic.screensaver J2SE logger.

Tip: Treat this as though it were part of a game loop. In general, it's a good idea not to allocate ('new') any objects after init unless they will not be deleted. This will yield smoother animation and no pauses from the garbage collector.

Parameters:

g - Graphics context used to draw to the screensaver window.

renderFrame

public final void renderFrame()

Called by the native layer to render the next frame.

Overrides:

renderFrame in class ScreensaverBase
