This event is triggered when the designer transitions out of edit mode, which could be due to the user completing their modifications or cancelling the edit operation. It provides an opportunity to execute custom logic after editing has concluded, such as validation, cleanup, or updating other parts of the UI in response to the changes made.

Listeners can use this event to perform actions that need to occur once editing is no longer active, ensuring that any necessary adjustments or checks are made following the edit session.
