public abstract class TclEvent

This is an abstract class that describes an event in the Jacl implementation of the notifier. It contains package protected fields and methods that are accessed by the Jacl notifier. Tcl Blend needs a different implementation of the TclEvent base class. The only public methods in this class are processEvent() and sync(). These methods must appear in both the Jacl and Tcl Blend versions of this class.
