Description
Occurs when a change occurs in the action list.
Write an OnChange event handler to update your application in response to changes in the action list. Changes to the action list that trigger an OnChange event include changes to an action category or to the action list's image list.
Note: The action list automatically informs the actions in the list when an OnChange event occurs. You need only provide an OnChange event handler for application-specific responses.
OnChange is an event handler of type TNotifyEvent.
