public class LCSiGMLURLPlayer
extends java.applet.Applet

An LCSiGMLURLPlayer is a simple signed animation player applet which communicates with enclosing HTML/javascript using the (Netscape/Mozilla-defined) LiveConnect protocol.

This class assumes that the following javascript event-handler method calls are supported:

     playerIsReadyForAvatar([String] defaultAvatar); // CURRENTLY DISABLED
     playerLoadAvatarIsDone([String] avatar);
     playerLoadFramesHasStarted();
     playerLoadFramesProgress([int] nSigns, [int] nFrames);
     playerLoadFramesIsDone([boolean] framesOK, [int] nSigns, [int] nFrames);
     playerIsAtFrameAndSign(
         [int] frameIndex, [int] signIndex, [String] gloss);
     playerIsAtFrame([int] frameIndex);
     playerIsDroppingFrame([int] frameIndex);
     playerAnimationIsDone([int] frameCount);
 

The playerIsReadyForAvatar() callout is currently disabled, since the avatar-load sequence it is intended to trigger is not supported by the Windows IE/LiveConnect implementation. (It works fine with Safari on Mac OS X, and with Firefox on both Mac OS X and Windows.)
