Would you mind explaining this - I never saw the benefit of a sealed class. Using myself as an example. Say I develop some kick-ass OOP framework. There is no way in hell I can forsee every possible use of the classes I created. So why would I want to limit the usefulness of a class - it goes totally against the OOP principles. Imagine the TList class was a sealed classes. We would never have been able to create a TObjectList, TInterfaceList, TStringList, etc... and reusing the basic implementation from TList to save time and code reuse. Not to shoot down your efforts or anything, I just don't understand the point of a sealed class. It sounds more like something Microsoft would implement to stop developers from reusing their classes like "Outlook Bar" and extend it to something much better than the standard one included in MS Office. -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
