Hi David,
The correct way is to create a resizeStack handler like this:
on resizeStack
modResizeStack
pass resizeStack
end resizeStack
on modResizeStack
-- do stuff here
end modResizeStack
and a button would contain a script like
on mouseUp
modResizeStack
end mouseUp
Now, you can call the modResizeStack handler without worrying about
an error. If the only reason for passing the resizeStack message is
you using the geometry manager, you don't really need to pass the
resizeStack message and the following would be sufficient:
on resizeStack
revUpdategeometry
-- do stuff here
end resizeStack
Now you could safely call the resizeStack handler using
on mouseUp
resizeStack
end mouseUp
If you don't want to change your scripts at the risk of breaking
them, you can prevent the error from popping up by means of a try
control structure:
on mouseUp
try
resizestack
end try
end mouseUp
As a rule, all message send by a script, need to be handled in
another script. Messages that are triggered by an event, such as an
actual mouseClick or mouseMove, can go unhandled. (This is different
from HyperCard, where all messages recognised as valid HyperTalk can
go unhandled).
Best,
Mark

Spent hours trying to track this down...
send "resizeStack" to card 1
Could not get it to work.
Then tried this. Create a blank stack - on the card script add:
on mouseUp
beep
pass mouseUp
end mouseUp
And put an empty button on a card. Clicking on the button gives you
a very
pleasing beep. But put this script in the button:
on mouseUp
send "mouseUp" to card 1
end mouseUp
And you get an error! Remove the "pass mouseUp" from the card
script and
everything works.
OK - so my problem is how do you send "resizeStack" messages. I
don"t want
to not pass this message?
