# Examples

on deleteButton -- prevent the deletion by immediately undoing it beep send "undo" to this card in 5 milliseconds end deleteButton

# Description

Handle the deleteButton message if you want to perform cleanup before a button is removed from the stack.

The actual deletion is not triggered by the deleteButton message, so trap the message and not allowing it to pass does not prevent the button from being removed.

However, the undo command will restore a button after it is deleted by the user.
