C++ (Cpp) TDocument::NotifyViews Examples

Example #1

File: document.cpp Project: Darkman-M59/Meridian59_115

//
/// Notifies the views of the current document and the views of any child documents
/// of a change. In contrast to QueryViews, NotifyViews sends notification of an
/// event to all views and returns true if all views returned 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.
//
