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. Examplesset 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
