Represents the method that will handle the SessionSwitch event.
public delegate void SessionSwitchEventHandler(object sender, SessionSwitchEventArgs e);
The source of the event.
A SessionSwitchEventArgs indicating the type of the session change event.
When you create a SessionSwitchEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see NIB: Events and Delegates.
