class WClass from WNT inherits TShared from MMgt
|
|
|
|
---Purpose: 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.
