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.
