Kerry, I know you ROCK so much, so I'm sorry, but I'll have to
correct on this one!
The point is not from which "Scope" the miaw is closed. The point is
from which scope the event closing the MIAW originates.
This is so for a number of complex object types in Director:
An event from originating from the complex object itself leading to
it's own destruction, will lead to a crash, presumably because "the
event can not terminate in the call stack" or some techno babble.
So it is central that the event closing the MIAW is an event
originating from another object, in this case the stage. That is why
people bother to store flags or references in globals.
Still though if you feel a little adventurous and like D8's
timeOutObjects, I personally find my own solution below quite
elegant: ;-)
(And I've posted it here just recently, so what's the bleedin'
problem with you folks?)
In the Miaw have these 2 scripts:
(requires D8)
--------<movie script>--------
on closeWindow
script("miawCloserClass").new(the activeWindow)
end
--------</movie script>--------
--------<parent script "miawCloserClass">--------
--miawCloserClass
property pWindow
on new me, aWindow
pWindow = aWindow
tell the stage to timeOut(me.string).new(0, #dummy , me)
end
on exitFrame me, aTimer
aTimer.forget()
pWindow.forget()
end
--------</parent script "miawCloserClass">--------
That should rid you completely of the Miaw... unless you have stored
references to the Miaw.
You can structure the above code differently; pass or not pass
arguments, and even place the "miawCloserClass" script in the stage.
All that matters is that the "miawCloserClass" object is placed in
the timeOutList of the stage, and not of the window to be destroyed.
