deleteScrollbar

Type

message

Summary

Sent to a scrollbar just before it is removed from the stack.

Syntax

deleteScrollbar

Description

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

The actual deletion is not triggered by the deleteScrollbar message, so trapping the message and not allowing it to pass does not prevent the scrollbar from being removed.

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

Examples

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