I'm in the midst of a project in which I'm adding sound to some artistic 
work I've been doing in Squeak for quite a few years now. I want a sound to 
be played when (1) the mouse cursor enters a morph which is one of my own 
subclasses of RectangleMorph; and then (2) the mouse cursor becomes 
"quiet". Maybe this is not the right way to do this, but here's how I'm 
thinking of doing it:

On mouseEnter, create a Delay and then fork a process which waits on the 
Delay and plays the sound. (Duration of the Delay is an artistic decision 
based on context.)

On mouseMove, if the Delay is notNil and is being waited on, "reset it".

On mouseLeave, kill the process waiting on the Delay if it hasn't already 
fired.

It looks to me from reading the code (Squeak 4.3) that I can reset the 
Delay using the Delay class method scheduleDelay: -- but [I haven't tried 
it yet ...] this makes me nervous. scheduleDelay: is labelled Private. I 
think that's telling me that calling this method from application code is a 
No-no. I'm also nervous about what I might need to do regarding the 
semaphore.

Comments please? Is there an easier way to do this? I need some way to 
reset a Delay that's already being waited on to the original duration.

-Thanks in advance, Jim
