deleteStack

Type

message

Summary

Sent to the current card of a stack that's about to be deleted.

Syntax

deleteStack

Description

Handle the deleteStack message if you want to perform cleanup before a stack is deleted from its stack file.

The actual deletion is not triggered by the deleteStack message, so trapping the message and not allowing it to pass does not prevent the stack from being removed.

If a stack's file is deleted with the delete file command (or by the user), and the stack itself is not open, no deleteStack message is sent.

Examples

on deleteStack -- warn the user
    if the mainStack of the owner of the target \
      is not the owner of the target then -- it's a substack
        answer "This stack will be permanently deleted the" && \
          "next time you save the file."
    end if
    pass deleteStack
end deleteStack
