Say you have a group that you want to do some tidying up if a user
deletes
it - and so you put a handler like this in the group itself:
on deleteGroup
beep
doSomeTidying
pass deleteGroup
end deleteGroup
Which works fine if it is a toplevel group - but when this group is
inside
another group deleting the toplevel group triggers a deleteGroup
message
which travels up the hierarchy to the card - but no deleteGroup
messages are
sent from the inner groups - this means you can't attach appropriate
behaviors to the groups.
Wandering if anyone has looked at this - I can't think how to do it as
deleteGroup is sent after deletion so even a frontscript would not
be able
to tell what was inside a deleted group. Even the new closeControl
message
does not seem to be sent in these circumstances?
David,
Maybe you'll need to check the child objects of the group before you
delete the parent group. If they have child groups delete them first
from the "inside out", so that each group is deleted individually and
so triggers the deleteGroup message.
repeat with x= 1 to the number of groups in group "parent"
if there is a group x of group "parent" then
delete group x of group "parent"
else
exit repeat
end if
end repeat
