IWindow

Describes system window. Could be used without form as well. In case of using window with a form, do not change events and try to avoid using any methods(they are for internal usage by form or if window is not associated with form) except probably for getters(but use form's methods instead). Release() should not delete self, it should destroy system window if exists. Delete window class instance should be handled by application object.

You can find more information in comments below.
