Detailed Description

Manager hook class.

Library: ilvmgr

This class is used to monitor events that occur within views associated with a manager. Instances of this class are called event hooks. They are used to notify the user of any event that occurs within a manager view, before the event is sent to view interactors, object interactors, or accelerators.

Event hooks are installed on managers using IlvManager::installEventHook and removed using IlvManager::removeEventHook.

Deleting a manager will delete the event hooks installed on it.
