WNT_WClass Class Reference

This class defines a Windows NT window class. A window in Windows NT is always created based on a window class. The window class identifies the window procedure that processes messages to the window. Each window class has unique name ( character string ). More than one window can be created based on a single window class. For example, all button windows in Windows NT are created based on the same window class. The window class defines the window procedure and some other characteristics ( background, mouse cursor shape etc. ) of the windows that are created based on that class. When we create a window, we define additional characteristics of the window that are unique to that window. So, we have to create and register window class before creation of any window. Of course, it's possible to create a new window class for each window inside the Window class and do not use the WClass at all. We implemented this class for sake of flexibility of event processing.
