cantDelete

set [the] cantDelete of card ¬
to trueOrFalse
set [the] cantDelete of bkgnd ¬
to trueOrFalse
set [the] cantDelete of stack ¬
to trueOrFalse

The cantDelete property returns or sets whether a user can delete a specified card, background, or stack. It corresponds to the Can’t Delete check box in the Card Info, Background Info, and Protect Stack dialog boxes.

The default value is false (meaning that a card, background, or stack can be deleted).

Note: Setting the cantDelete of a stack to true doesn't prevent the user from deleting the stack by dragging it to the Trash.

Examples

set the cantDelete of this card to true
set the cantDelete of first card of bkgnd 2 to false
set the cantDelete of this background to true
set the cantDelete of this stack to true
set the cantDelete of stack "Home" to true

Demo Script

on cantDeleteDemo
set cantDelete of this card to true
domenu "Delete Card"
end cantDeleteDemo
