# Syntax

set the cantModify of stack to { true | false }

# Examples

set the cantModify of stack "Help" to true

# Description

Use the cantModify property to protect the objects in a stack from changes.

If a stack's cantModify property is set to true, the user cannot choose any tool except the Browse tool. This prevents the user from moving, resizing, creating, or deleting objects.

If a stack's cantModify is false and its label property is empty, an asterisk (*) appears in the stack title bar, indicating that the stack can be modified.

The cantModify property restricts user actions, but does not affect actions performed by a handler. To prevent either user action or a handler from deleting a card, group, or stack, use the cantDelete property.

>*Important:* If a modifiable stack is open in an editable window, > the modifiable stack takes precedence over any non-modifiable > stacks, because its mode property is lower. This means that menu > items (such as Object ? Stack Properties) that act on the current > stack may not be able to operate correctly with a stack whose > cantModify is set to true as long as another, modifiable stack is > open.
