示例1: eventInfo
//
/// Queries the views of the current document and the views of any child documents
/// about a specified event, but stops at the first view that returns true. In
/// contrast to NotifyViews(), QueryViews returns a pointer to the first view that
/// responded to an event with a true result. The event, EV_OWLNOTIFY, is sent with
/// an event code (which is private to the particular document and view class) and a
/// long argument (which can be cast appropriately to the actual type passed in the
/// argument of the response function).
//
