> What is a nilEvent?
it is an event with no associated property. :>
normally.. events have an association with them.. such as
a form, menu, list etc. inside your eventloop code you will
wait for an event to occur in order to process it.
in some cases, you dont have a system event to process, so you
use a programmed event (timeout based) to ensure something is
executed periodically.. this is the nilEvent.. it has no
association..
you will use the nilEvent in animations.. that is, if you
want to move an object on the screen - but dont have a real
event to process.. :>
cheers.
