Class DisplayScheduler

java.lang.Object
  jarp.DisplayScheduler

All Implemented Interfaces:

ThreadCompletionChecker

public class DisplayScheduler
extends java.lang.Object
implements ThreadCompletionChecker

A DisplayScheduler sets up a thread to drive the display() method of a GLDrawable. For efficiency, it sets up the rendering thread for the drawable to be its own internal thread, so it can not be combined with manual repaints of the surface.

Field Summary

static int

PERIOD_MS

Constructor Summary

DisplayScheduler(javax.media.opengl.GLAutoDrawable jadrawable)
Creates a new GLDisplayScheduler for the given drawable.

Method Summary

FrameAnimationSynch	getFrameAnimationSynch() Returns this display-scheduler's frame-animation-synchronisation object.
void	requestDisplayNow() Registers a request for display to be invoked on our GLDrawable.
void	start() Starts this display scheduler.
void	stop() Stops this display scheduler, blocking until the display scheduling thread has finished.
void	waitForCompletion() Thread completion checker method: assumes we've previously had a stop() call and now wish to wait until it is known that the display-scheduler thread has indeed stopped.
