Hi Devon,
I don't think that is a solution. The problem with your suggestion
is that "this stack" does not evaluate to "myApp".
Likewise, when I write: "the short name of this cd", it never
evaluates to the name of the card that the user is quitting from.
Right, that's what Devin's suggestion evaluates -- whether the card or
stack that gets the shutdownrequest message is yours or not. If the
stack is not a toplevel stack or the stack isn't visible (assuming your
standalone mainstack is always visible) then the stack that received the
message isn't one you want to handle. You could also check this way:
if the short name of this stack is the mainstack of this stack then...
which would be true if it's your stack and false if it's not. There are
other tests you could devise if you have several stacks you want to
respond to.
In any case, you'd only evaluate the data if the stack that is being
closed is yours, and you'd just pass the closestackrequest message if it
wasn't. For example:
on closeStackRequest
if the short name of this stack is the mainstack of this stack then
-- do your data evaluation, it's your stack
end if
pass closeStackRequest -- pass it in all cases
end closeStackRequest
I agree that you are probably seeing the effects of a multi-window
environment (something HyperCard didn't have.) The stack you are looking
at isn't necessarily the first recipient of a system message. (See
"defaultstack" in the dictionary; it's a new concept for
ex-HyperCarders.) Stacks can be at the front of the message hierarchy
even while not being visible, or not being "physically" in front. Using
the above technique, you bypass the problem by only responding to the
message if the stack that receives it is yours.
