Hi,

When is an application object instantiated in the following case:

For example,
(defclass mycircle ....)
(define-presentation-type mycircle ....)
(define-presentation-method ...
	(draw-circle* ....))

In the above situation, is the application-object instantiated when we
draw the circle?

Thanks!

Regards,
t|ng

This depends on the method.  ACCEPT for instance is responsible for
parsing a representation of an application object  and then perhaps
instantiating it (if it hasn't been given an already-existing
object), while PRESENT will be given a preexisting, instantiated
object.
