cantModify

set [the] cantModify of stack ¬

    to trueOrFalse

The cantModify property returns or sets whether a stack can be changed in any way. It corresponds to the Can’t Modify check box in the Protect Stack dialog box.

Setting the cantModify of a stack to true selects both the Can’t Modify Stack check box and the Can’t Delete Stack check box in the Protect Stack dialog box. When cantModify is true, a padlock appears in the menu bar.

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

Examples

set the cantModify of this stack to true

set the cantModify of stack "My Kiosk" to true
