deleteGroup

Type

message

Summary

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

Syntax

deleteGroup

Description

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

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

Deleting the last card on which a group appears does not remove the group from the stack, so it does not cause a deleteGroup message to be sent.

Ungrouping a group does not cause a deleteGroup message to be sent.

A deleteBackground message is sent after the deleteGroup message.

Examples

on deleteGroup -- remove the group being deleted from a list
  get lineOffset(the short name of the target,field "Groups List")
  delete line it of field "Groups List"
  pass deleteGroup
end deleteGroup
